Manufactured from Grade 8 steel and finished with a zinc yellow dichromate coating, this fastener is built for high-strength bolted assemblies where corrosion resistance and tensile performance are both required. Grade 8 steel carries a higher proof load and tensile strength than Grades 2 or 5, making it appropriate for structural, mechanical, and equipment-mounting applications. The zinc yellow dichromate finish adds a layer of corrosion protection while providing a visible indicator of the Grade 8 classification. Compliance with ASME B18.2.1 and SAE J429 ensures dimensional and mechanical conformance to recognized industry standards.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for general industrial, maintenance, and mechanical assembly work where high-strength inch-series hardware is specified. Common applications include securing machine components, equipment frames, brackets, and structural connections that require a fully threaded grip. The 1\/4-20 UNC thread pattern is one of the most widely used coarse-thread sizes in trade and industrial settings, compatible with standard nuts, inserts, and tapped holes of the same specification. The minimum order quantity is 50 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high proof load and tensile strength\u003c\/li\u003e\n  \u003cli\u003eFully threaded body along the full 1-inch length under head\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion resistance and grade identification\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC coarse thread standard for broad tooling and hardware compatibility\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards and SAE J429 mechanical property requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with 1\/4-20 UNC nuts, threaded inserts, and tapped holes conforming to UNC coarse-thread specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanics, maintenance technicians, or electricians using a standard hex wrench or socket driver sized for the 1\/4-inch hex head. Ensure the mating thread is clean and free of debris before engagement. Do not exceed the rated torque for the Grade 8 fastener class and the material being fastened. Inspect the zinc coating for damage before installation in corrosive environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D39004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709849043250,"sku":"D39004","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c18b4e6b9570c32cf7b7d05ecbfd3ff0.jpg?v=1788461329","url":"https:\/\/voomisupply.com\/products\/value-collection-d39004-1-4-20-x-1-in-grade-8-hex-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
