href=\"https:\/\/www.rlfasteners.com\/pt\/automotive-solution\/\" target=\"_blank\" rel=\"noreferrer noopener\">Tipos de fixadores automotivos<\/a> s\u00e3o mais f\u00e1ceis de comparar quando os compradores sabem ler a string de especifica\u00e7\u00e3o completa. Um n\u00famero de pe\u00e7a pode incluir o padr\u00e3o, di\u00e2metro, passo da rosca, comprimento, grau de resist\u00eancia, material, revestimento e, \u00e0s vezes, um c\u00f3digo do cliente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para engenheiros e equipes de compras, esta n\u00e3o \u00e9 apenas uma quest\u00e3o de papelada. Uma letra ou n\u00famero errado pode alterar o ajuste da rosca, o comportamento do torque, a resist\u00eancia \u00e0 corros\u00e3o ou o resultado da montagem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Should_Buyers_Decode_The_Full_Fastener_Code\"><\/span><strong>Por que os compradores devem decodificar o c\u00f3digo completo do fixador?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Os compradores devem decodificar o c\u00f3digo completo do fixador porque o nome do produto sozinho n\u00e3o \u00e9 suficiente. Um \"parafuso sextavado\" ou \"porca de flange\" pode ter muitos tamanhos, graus, revestimentos e padr\u00f5es poss\u00edveis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Na <a href=\"https:\/\/www.rlfasteners.com\/pt\/industrial-fastening\/\" target=\"_blank\" rel=\"noreferrer noopener\">ind\u00fastria de fixadores automotivos<\/a>, uma pequena diferen\u00e7a pode criar um problema real de montagem. Um parafuso com o passo errado pode danificar a rosca correspondente. Uma porca com a classe de resist\u00eancia errada pode n\u00e3o corresponder ao parafuso. Uma mudan\u00e7a de revestimento tamb\u00e9m pode afetar a resist\u00eancia \u00e0 corros\u00e3o ou o comportamento de aperto.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O objetivo \u00e9 simples: garantir que a ordem de compra, o desenho, a amostra e o relat\u00f3rio de inspe\u00e7\u00e3o descrevam a mesma pe\u00e7a.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Does_A_Fastener_Specification_String_Usually_Include\"><\/span><strong>O que uma string de especifica\u00e7\u00e3o de fixador geralmente inclui?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Uma string de especifica\u00e7\u00e3o de fixador geralmente inclui o tipo de pe\u00e7a, padr\u00e3o, di\u00e2metro, passo, comprimento, grau, material e acabamento. O pedido pode mudar dependendo do sistema do fornecedor ou cliente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Uma string de exemplo pode parecer assim:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Parafuso de flange DIN 6921 M8 x 1,25 x 30 10.9 zinco preto<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aqui est\u00e1 como l\u00ea-lo:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Elemento do C\u00f3digo<\/strong><\/td><td><strong>Significado<\/strong><\/td><td><strong>O que Verificar<\/strong><\/td><\/tr><tr><td>DIN 6921<\/td><td>Padr\u00e3o dimensional<\/td><td>O desenho requer este padr\u00e3o?<\/td><\/tr><tr><td>M8<\/td><td>Di\u00e2metro nominal<\/td><td>Corresponde ao furo ou porca?<\/td><\/tr><tr><td>1.25<\/td><td>Passo da rosca<\/td><td>\u00c9 rosca grossa ou fina?<\/td><\/tr><tr><td>30<\/td><td>Comprimento<\/td><td>O comprimento medido est\u00e1 correto?<\/td><\/tr><tr><td>10.9<\/td><td>Grau de resist\u00eancia<\/td><td>Corresponde ao requisito de carga?<\/td><\/tr><tr><td>Zinco preto<\/td><td>Tratamento de superf\u00edcie<\/td><td>Atende \u00e0s necessidades de corros\u00e3o ou apar\u00eancia?<\/td><\/tr><tr><td>Parafuso de flange<\/td><td>Tipo de fixador<\/td><td>O estilo da cabe\u00e7a se encaixa na junta?<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Este m\u00e9todo ajuda os compradores a comparar os tipos de fixadores automotivos sem adivinhar a partir de fotos ou nomes de produtos curtos.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Do_SAE_Automotive_Fastener_Standards_Affect_Orders\"><\/span><strong>Como os padr\u00f5es de fixadores automotivos SAE afetam os pedidos?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Os padr\u00f5es de fixadores automotivos SAE afetam os pedidos quando o desenho usa fixadores da s\u00e9rie polegada ou refer\u00eancias de especifica\u00e7\u00e3o norte-americanas. Por exemplo, SAE J429 cobre os requisitos mec\u00e2nicos e de material para parafusos, parafusos prisioneiros e U-bolts de a\u00e7o da s\u00e9rie polegada de at\u00e9 1-1\/2 polegadas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Isso \u00e9 importante porque os padr\u00f5es SAE, ISO, DIN, ANSI, JIS e GB nem sempre descrevem a mesma pe\u00e7a. Dois fixadores podem parecer semelhantes, mas suas dimens\u00f5es, marca\u00e7\u00f5es, materiais ou regras de inspe\u00e7\u00e3o podem diferir.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Antes de substituir um padr\u00e3o por outro, os compradores devem confirmar o requisito real do desenho. Isso \u00e9 especialmente importante para programas de reparo, pedidos de exporta\u00e7\u00e3o e cadeias de suprimentos globais mistas.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image2-1-1024x512.webp\" alt=\"\" class=\"wp-image-2934\" srcset=\"https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image2-1-1024x512.webp 1024w, https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image2-1-300x150.webp 300w, https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image2-1-768x384.webp 768w, https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image2-1-18x9.webp 18w, https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image2-1.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Should_Buyers_Grade_Automotive_Fasteners\"><\/span><strong>Como os compradores devem classificar os fixadores automotivos?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Os compradores devem classificar os fixadores automotivos verificando a classe de resist\u00eancia ou marca\u00e7\u00e3o de grau em rela\u00e7\u00e3o \u00e0 aplica\u00e7\u00e3o. Fixadores m\u00e9tricos frequentemente usam classes como 8.8, 10.9 e 12.9. Pe\u00e7as da s\u00e9rie polegada podem usar marca\u00e7\u00f5es de grau SAE.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O grau informa aos compradores sobre o n\u00edvel de resist\u00eancia mec\u00e2nica. Mas um grau mais alto nem sempre \u00e9 a escolha certa. A pe\u00e7a correspondente, o valor de torque, a profundidade da rosca e o material tamb\u00e9m devem corresponder ao grau.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Por exemplo, quando um desenho especifica um parafuso com flange, os compradores podem comparar os campos de tamanho, material e acabamento com<a href=\"https:\/\/www.rlfasteners.com\/pt\/products\/din6921-factory-direct-price-m8-m24-flanged-hexagon-head-bolts\/?utm_source=chatgpt.com\"> parafusos de cabe\u00e7a hexagonal com flange DIN6921<\/a> antes de confirmar o que o projeto precisa. Este tipo de p\u00e1gina de produto \u00e9 \u00fatil porque separa detalhes de tamanho, material, acabamento, equipamento de teste e embalagem.<\/p>\n\n\n\n<style>\n  .product-card {\n    display: flex;\n    align-items: center;\n    justify-content: center;\n    height: 400px;\n    border: 1px solid #ddd;\n    border-radius: 10px;\n    overflow: hidden;\n    box-shadow: 0 4px 10px rgba(0, 0, 0, 0.1);\n    max-width: 900px;\n    margin: 0 auto;\n    gap: 40px;\n    padding: 20px;\n    box-sizing: border-box;\n  }\n\n  .product-left,\n  .product-right {\n    flex: 1 1 50%;\n    display: flex;\n    flex-direction: column;\n    justify-content: center;\n    align-items: center;\n    text-align: center;\n  }\n\n  .product-left {\n    gap: 20px;\n  }\n\n  .product-title {\n    font-size: 24px;\n    font-weight: 700;\n    color: #b59d53;\n    margin: 0;\n  }\n\n  .product-button {\n    background-color: transparent;\n    color: #b59d53;\n    border: 2px solid #b59d53;\n    padding: 12px 24px;\n    font-size: 15px;\n    border-radius: 6px;\n    cursor: pointer;\n    transition: all 0.3s ease;\n    text-decoration: none;\n    display: inline-block;\n  }\n\n  .product-button:hover {\n    border-color: #333333;\n    color: #333333;\n    transform: scale(1.1);\n  }\n\n  .product-right img {\n    max-width: 100%;\n    max-height: 360px;\n    object-fit: contain;\n    border-radius: 10px;\n  }\n\n  @media (max-width: 768px) {\n    .product-card {\n      flex-direction: column;\n      height: auto;\n      padding: 15px;\n      gap: 15px;\n    }\n\n    .product-left,\n    .product-right {\n      flex: none;\n      width: 100%;\n      text-align: center;\n    }\n\n    .product-right img {\n      max-height: 300px;\n      margin-bottom: 15px;\n    }\n\n    .product-left {\n      order: 2;\n      gap: 10px;\n      align-items: center;\n    }\n\n    .product-right {\n      order: 1;\n    }\n  }\n<\/style>\n\n<div class=\"product-card\">\n  <div class=\"product-right\">\n    <img decoding=\"async\" src=\"https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2022\/07\/%E4%B8%BB%E5%9B%BE-01-16.jpg\" alt=\"DIN127 Arruelas de press\u00e3o de mola pretas\" \/>\n  <\/div>\n  <div class=\"product-left\">\n    <p class=\"product-title\">DIN127 Arruelas de press\u00e3o de mola pretas<\/p>\n    <a href=\"https:\/\/www.rlfasteners.com\/pt\/products\/din127-black-split-spring-lock-washers\/\" target=\"_blank\" class=\"product-button\">Mais detalhes<\/a>\n  <\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Do_Thread_Size_And_Tolerance_Codes_Tell_You\"><\/span><strong>O que os c\u00f3digos de tamanho e toler\u00e2ncia de rosca dizem a voc\u00ea?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Os c\u00f3digos de tamanho e toler\u00e2ncia de rosca informam se o fixador pode se encaixar corretamente na pe\u00e7a correspondente. O di\u00e2metro sozinho n\u00e3o \u00e9 suficiente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para roscas m\u00e9tricas, os compradores podem ver c\u00f3digos como M6, M8 ou M10, seguidos por um passo como 1,0, 1,25 ou 1,5. O passo explica a dist\u00e2ncia entre as roscas. Se o passo estiver errado, a pe\u00e7a pode come\u00e7ar a rosquear, mas danificar a junta.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Os c\u00f3digos de toler\u00e2ncia tamb\u00e9m s\u00e3o importantes. Um desenho pode incluir requisitos de ajuste como 6g ou 6H. Esses c\u00f3digos ajudam a definir qu\u00e3o apertada ou solta deve ser a rela\u00e7\u00e3o da rosca.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Se o n\u00famero da pe\u00e7a n\u00e3o mostrar o passo ou a toler\u00e2ncia, pergunte ao fornecedor antes de amostrar. Este \u00e9 um dos erros mais comuns ao comparar tipos de fixadores automotivos de diferentes mercados.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image3-2-1024x512.webp\" alt=\"\" class=\"wp-image-2935\" srcset=\"https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image3-2-1024x512.webp 1024w, https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image3-2-300x150.webp 300w, https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image3-2-768x384.webp 768w, https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image3-2-18x9.webp 18w, https:\/\/www.rlfasteners.com\/wp-content\/uploads\/2026\/07\/image3-2.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Do_Surface_Treatment_Abbreviations_Mean\"><\/span><strong>O que os nomes de tratamento de superf\u00edcie significam?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As abrevia\u00e7\u00f5es de tratamento de superf\u00edcie descrevem o acabamento aplicado ao fixador.

Pode influenciar a resist\u00eancia \u00e0 corros\u00e3o, a espessura do revestimento, o atrito e o controle de torque. Um revestimento que funciona para um painel de carroceria pode n\u00e3o ser correto para uma junta de motor ou chassi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para juntas de travamento ou relacionadas a torque, os compradores devem ler cuidadosamente a descri\u00e7\u00e3o da porca. Quando a pe\u00e7a necessita de uma fun\u00e7\u00e3o de travamento controlada,<a href=\"https:\/\/www.rlfasteners.com\/pt\/products\/custom-12-point-nuts-prevailing-torque-type-all-metal-twelve-point-flange-nuts\/?utm_source=chatgpt.com\"> porcas de flange com torque prevalente totalmente met\u00e1licas<\/a> podem ser usadas como refer\u00eancia para verificar os campos de tamanho, material, acabamento, forma e padr\u00e3o antes de confirmar o desenho final.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Are_Three_Types_Of_Automotive_Fasteners_Buyers_Should_Decode_First\"><\/span><strong>Quais s\u00e3o os tr\u00eas tipos de fixadores automotivos que os compradores devem decodificar primeiro?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Tr\u00eas tipos de fixadores automotivos que os compradores devem decodificar primeiro s\u00e3o parafusos, porcas e arruelas. Estes aparecem em muitos sistemas de ve\u00edculos e frequentemente carregam detalhes importantes de especifica\u00e7\u00e3o.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Parafusos geralmente precisam ser verificados quanto a di\u00e2metro, passo, comprimento, estilo da cabe\u00e7a, grau e revestimento. Porcas precisam ser verificadas quanto a correspond\u00eancia de rosca, forma, classe de resist\u00eancia e recurso de travamento. Arruelas precisam ser verificadas quanto a di\u00e2metro interno, di\u00e2metro externo, espessura, material e acabamento de superf\u00edcie.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Outros tipos de fixadores automotivos incluem parafusos, pinos, <a href=\"https:\/\/www.rlfasteners.com\/pt\/products\/oem-blind-rivets-types-of-automotive-rivet\/\" target=\"_blank\" rel=\"noreferrer noopener\">rebites<\/a>, <a href=\"https:\/\/www.rlfasteners.com\/pt\/products\/custom-black-bushing-bearing-steel-flanged-bushing\/\" target=\"_blank\" rel=\"noreferrer noopener\">buchas<\/a>, insertos helicoil e pe\u00e7as estampadas. Essas pe\u00e7as geralmente precisam de mais controle de desenho porque sua forma pode afetar o ajuste e a montagem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para pedidos B2B, os compradores n\u00e3o devem aprovar tipos de fixadores automotivos apenas pelo nome. O desenho, a amostra e a string de especifica\u00e7\u00e3o devem corresponder antes da produ\u00e7\u00e3o em massa.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Can_Testing_Confirm_The_Specification\"><\/span><strong>Como o teste pode confirmar a especifica\u00e7\u00e3o?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Testes podem confirmar se o fixador entregue corresponde \u00e0 string de especifica\u00e7\u00e3o. Verifica\u00e7\u00f5es visuais s\u00e3o \u00fateis, mas n\u00e3o podem confirmar tudo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O material pode precisar de verifica\u00e7\u00e3o atrav\u00e9s de um espectr\u00f4metro de leitura direta. A resist\u00eancia pode precisar de teste de tra\u00e7\u00e3o. A dureza pode ser verificada atrav\u00e9s dos m\u00e9todos Brinell, Rockwell ou Vickers. Testes de espessura de revestimento e de n\u00e9voa salina tamb\u00e9m podem ser necess\u00e1rios quando a resist\u00eancia \u00e0 corros\u00e3o \u00e9 importante.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00c9 aqui que a CNRL Fasteners pode apoiar a revis\u00e3o t\u00e9cnica. A empresa lista <a href=\"https:\/\/www.rlfasteners.com\/pt\/equipment\/\" target=\"_blank\" rel=\"noreferrer noopener\">equipamentos de teste<\/a> como paqu\u00edmetros, calibradores passa\/n\u00e3o passa, m\u00e1quinas de teste de tra\u00e7\u00e3o, testadores de dureza, testadores de n\u00e9voa salina, ferramentas de espessura de galvanoplastia e equipamentos de detec\u00e7\u00e3o 3D em suas p\u00e1ginas de produtos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para equipes de compras, este suporte de teste ajuda a reduzir disputas. O comprador pode comparar o resultado da inspe\u00e7\u00e3o com o desenho em vez de depender apenas das descri\u00e7\u00f5es do fornecedor.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Should_Be_Included_In_A_Clear_B2B_Fastener_Order\"><\/span><strong>O que deve ser inclu\u00eddo em um pedido claro de fixadores B2B?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Um pedido claro de fixadores B2B deve incluir a especifica\u00e7\u00e3o completa, n\u00e3o apenas o nome da pe\u00e7a. Isso ajuda o fornecedor a cotar, amostrar, fabricar e inspecionar a pe\u00e7a correta.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Um pedido pr\u00e1tico deve incluir:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Tipo de pe\u00e7a:<\/strong> Parafuso, porca, arruela, pino, rebite, bucha ou parafuso<\/li>\n\n\n\n<li><strong>Padr\u00e3o:<\/strong> ISO, DIN, SAE, ANSI, JIS, GB ou desenho personalizado<\/li>\n\n\n\n<li><strong>Tamanho:<\/strong> Di\u00e2metro, passo da rosca, comprimento e toler\u00e2ncia<\/li>\n\n\n\n<li><strong>Nota:<\/strong> Classe de resist\u00eancia ou requisito de grau SAE<\/li>\n\n\n\n<li><strong>Material:<\/strong> A\u00e7o carbono, a\u00e7o liga, a\u00e7o inoxid\u00e1vel ou material personalizado<\/li>\n\n\n\n<li><strong>Tratamento de superf\u00edcie:<\/strong> Zinco, zinco preto, n\u00edquel, cromo, \u00f3xido preto, Dacromet ou H.D.G<\/li>\n\n\n\n<li><strong>Testes:<\/strong> Dureza, resist\u00eancia \u00e0 tra\u00e7\u00e3o, espessura do revestimento ou solicita\u00e7\u00e3o de n\u00e9voa salina<\/li>\n\n\n\n<li><strong>Embalagem:<\/strong> Caixa a granel, saco etiquetado, kit ou embalagem espec\u00edfica do cliente<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Isso torna o pedido mais f\u00e1cil de verificar antes da amostragem e mais f\u00e1cil de inspecionar antes do envio.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Read_The_Code_Before_Approving_Production\"><\/span><strong>Leia o c\u00f3digo antes de aprovar a produ\u00e7\u00e3o<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Tipos de fixadores automotivos devem ser decodificados antes que os compradores aprovem amostras ou produ\u00e7\u00e3o em massa. O nome do produto \u00e9 apenas a primeira pista. O c\u00f3digo completo informa aos compradores o tamanho, rosca, padr\u00e3o, material, grau, revestimento e requisito de inspe\u00e7\u00e3o.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para engenheiros, isso protege a montagem. Para equipes de compras, reduz pedidos errados, RFQs pouco claras e disputas com fornecedores.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Antes de confirmar um pedido, envie \u00e0 CNRL Fasteners o desenho, amostra, n\u00famero da pe\u00e7a, \u00e1rea de aplica\u00e7\u00e3o e requisitos de teste. Isso d\u00e1 ao fornecedor informa\u00e7\u00f5es suficientes para verificar se a string de especifica\u00e7\u00e3o corresponde \u00e0 condi\u00e7\u00e3o real de trabalho.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-width wp-block-button__width-50\"><a class=\"wp-block-button__link has-white-color has-text-color has-background has-link-color has-medium-font-size has-custom-font-size wp-element-button\" href=\"https:\/\/www.rlfasteners.com\/pt\/contact\/\" style=\"background-color:#b59d53\" target=\"_blank\" rel=\"noreferrer noopener\">Obtenha um or\u00e7amento gratuito<\/a><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Os tipos de fixadores automotivos s\u00e3o mais f\u00e1ceis de comparar quando os compradores sabem ler a string completa de especifica\u00e7\u00f5es.
