Manufactured from alloy steel with an Armor Coat finish for corrosion resistance, this screw features a socket cap head driven by a 1\/4-inch hex key. The 1-inch length under head and fully threaded shank make it suitable for through-hole and tapped-hole connections where maximum thread engagement is required. Conforms to ASME B18.3 standards. This fastener is installed by machinists, millwrights, pipefitters, and general maintenance trades across a wide range of service environments.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is used in equipment assembly, machine guarding, fixture fabrication, and general mechanical maintenance where a low-profile, high-torque fastener is needed. The hex socket drive allows for installation in tight or recessed spaces where a standard hex head wrench cannot reach. Fully threaded construction provides consistent clamping force along the entire shank length, making it well suited for shallow tapped holes and thin material applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 thread size for use with standard UNC tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-inch length under head, fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eArmor Coat finish provides corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for installation with a standard hex key or hex bit driver\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC socket cap screw for use in any application requiring a 5\/16-18 tapped hole with a 1-inch length under head fastener per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 1\/4-inch hex key or hex bit driver rated for the required torque. Ensure the tapped hole is clean and free of debris before threading. Do not exceed the rated torque for the thread size and material grade to avoid stripping threads or fastener failure. Always verify thread engagement depth meets the requirements of the joint design before final tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Armor Coat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: UST235940\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMOR COAT","offers":[{"title":"Default Title","offer_id":67911529234738,"sku":"UST235940","price":7740.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b713819eaa4c48166b78fa747a38153_ad5d45a8-87e6-4cef-825c-33c49af9d732.jpg?v=1791211607","url":"https:\/\/voomisupply.com\/products\/armor-coat-ust235940-socket-cap-screw-5-16-18-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
