Sized at 5\/16-18 UNC with a 2-1\/4 inch length under the head, this fastener is partially threaded and driven by a 1\/4 inch hex key. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and meets the dimensional and mechanical standards set by ASME\/ANSI B18.3 and ASTM A574. Machinists, millwrights, and maintenance technicians install these screws into tapped holes on machinery, fixtures, brackets, and structural assemblies across industrial and commercial settings.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for mechanical assemblies, fabrication work, and equipment maintenance where controlled clamping force and a low-profile socket drive are required. The partial threading allows the unthreaded shank to bear shear loads while the threaded end engages the tapped hole. It is commonly used in metal-to-metal fastening on production machinery, conveyor systems, pump housings, and structural steel components. Installers working under OSHA or facility maintenance standards will find this fastener meets widely referenced dimensional and strength specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread size for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e2-1\/4 inch length under head with partial threading for shear-load-bearing shank\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex socket drive for use with standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex socket cap screw for use in any application requiring a 5\/16-18 UNC tapped hole and a 1\/4 inch hex drive, following ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/4 inch hex key or socket driver. Ensure the mating tapped hole is clean, free of debris, and dimensionally correct for 5\/16-18 UNC thread engagement before driving the fastener. Power down and de-energize any equipment before performing fastener installation or replacement on live machinery. Thread lubricant or thread-locking compound may be applied per the assembly specification, but no specific values are assumed beyond manufacturer or job-spec requirements.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/4 inches\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\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.052 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 011213P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722193404210,"sku":"011213P","price":9013.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c98c7c847864b5b0595e44ded8d913e3.jpg?v=1788587129","url":"https:\/\/voomisupply.com\/products\/value-collection-011213p-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
