It features an 82-degree flat head profile that sits flush with or below the mating surface when properly seated, eliminating protrusion in high-clearance or aesthetic-critical assemblies. The hex socket drive accepts a 5\/16-inch hex key for high-torque installation in confined spaces. Manufactured from alloy steel with a black oxide finish, this screw delivers solid mechanical strength with moderate corrosion resistance. The fastener is fully threaded along its 7\/8-inch length on a 1\/2-13 UNC coarse thread form.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for general industrial, mechanical, and structural applications where a flush fastener profile is required. The UNC 1\/2-13 thread is one of the most common coarse-thread sizes in inch-standard assemblies, making this screw a frequent choice for machine frames, jigs, fixtures, and equipment panels. It is installed by machinists, millwrights, and maintenance technicians working on inch-standard equipment. The black oxide finish provides a low-reflectance appearance and light surface protection appropriate for indoor and controlled-environment use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush in standard countersunk holes per ASME\/ANSI B18.3\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive allows high-torque installation with a standard Allen key or hex bit\u003c\/li\u003e\n  \u003cli\u003eFully threaded 7\/8-inch body maximizes thread engagement across the full length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and shear strength for demanding assemblies\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces surface reflectance and adds light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an inch-standard UNC replacement or new-installation fastener for any assembly requiring a 1\/2-13 countersunk socket cap screw per ASME\/ANSI B18.3 and ASTM F835 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/16-inch hex key or hex socket bit driver. Power down or de-energize any equipment before fastener replacement in mechanical assemblies. A properly sized 82-degree countersink must be present in the mating material for the flat head to seat flush. Apply thread-locking compound or torque to specification per the equipment manufacturer's guidelines and applicable ASME standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7\/8 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82-degree Flat\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: 5\/16 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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F835\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\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: 721238PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720998617394,"sku":"721238PR","price":1030.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_cf99da8f-ca25-466d-9cb2-91665d6fdc05.jpg?v=1788572080","url":"https:\/\/voomisupply.com\/products\/value-collection-721238pr-flat-socket-cap-screw-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
