Fully threaded along its entire shank, this fastener is designed for high-strength bolted connections in demanding mechanical and structural applications. The Armor Coat finish provides corrosion resistance for use in environments where bare steel would be exposed to moisture or contaminants. Manufactured to ASME B18.2.1 and SAE J429 standards, it meets the dimensional and mechanical property requirements expected by trade professionals working in HVAC, plumbing, equipment mounting, and general mechanical assembly.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for residential and commercial applications where a high-strength, inch-series hex cap screw is required. Typical installation scenarios include equipment base mounting, bracket assembly, and structural connections that require a Grade 8 torque rating. The fully threaded design allows maximum thread engagement across a range of material thicknesses, making it a versatile choice for through-bolt and tapped-hole configurations. Installers working on HVAC curbs, condenser mounts, pump bases, and similar structural connections commonly specify Grade 8 hardware for these joints.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high-strength bolted connections\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for broad compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003eArmor Coat finish for enhanced corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head for a range of material stack thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement hex head cap screw for any application requiring a 3\/8-16 UNC, 1-1\/4 inch, Grade 8 fully threaded fastener conforming to ASME B18.2.1 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or trade professional familiar with high-strength fastener torque requirements for Grade 8 hardware. Always de-energize or shut down the equipment being serviced before disassembling or reassembling bolted joints. Use calibrated torque tools appropriate for 3\/8-16 fasteners and follow the torque specifications listed in the equipment manufacturer's service documentation. Inspect mating threads for damage or contamination before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 1-1\/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: 0.005 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: UST235768\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMOR COAT","offers":[{"title":"Default Title","offer_id":67911147258162,"sku":"UST235768","price":4877.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/441cdfc9bb6c638dec78d67eb2468182.jpg?v=1791204859","url":"https:\/\/voomisupply.com\/products\/armor-coat-ust235768-hex-head-cap-screw-3-8-16-x-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
