It is fully threaded and finished with an Armor Coat surface coating for corrosion resistance. Manufactured to ASME B18.2.1 and SAE J429 standards, this fastener is suited for high-strength bolted connections in mechanical, HVAC, and general trade assemblies where a fine-thread, inch-series cap screw is required. Grade 8 classification indicates a minimum tensile strength appropriate for demanding structural and equipment fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a broad range of commercial and industrial service applications where fine-thread engagement and high tensile strength are needed. Typical install scenarios include securing brackets, equipment housings, motor mounts, and structural assemblies on HVAC units, pumps, and mechanical equipment. The 5\/16-24 UNF thread is common in precision and high-vibration environments where fine-thread fasteners resist loosening better than coarse-thread alternatives. Installation is performed by licensed tradespeople or qualified technicians as part of larger assembly or equipment service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength in demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF fine thread for precision fit and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 1-1\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eArmor Coat finish provides corrosion protection for extended service life\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 standards for dimensional and mechanical compliance\u003c\/li\u003e\n  \u003cli\u003eInch measurement system, length measured under head per standard convention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance fastener for applications requiring a 5\/16-24 UNF fully threaded hex head cap screw in Grade 8 steel with Armor Coat finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians, plumbers, electricians, or mechanical contractors as part of equipment assembly or field service. Always de-energize and lock out equipment before replacing or installing fasteners on live machinery. Use the correct hex socket or wrench size for 5\/16 inch hex head fasteners to avoid rounding the head. Follow equipment manufacturer torque specifications and applicable mechanical codes when tightening Grade 8 fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\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: Armor Coat\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: 0.003 pounds\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: ARMOR COAT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UST235762\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMOR COAT","offers":[{"title":"Default Title","offer_id":67911264469298,"sku":"UST235762","price":3878.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3bd88ec5e941f59bf9deebd32af4877.jpg?v=1791208188","url":"https:\/\/voomisupply.com\/products\/armor-coat-ust235762-hex-head-cap-screw-5-16-24-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
