It features an 82-degree flat head with a 1\/4-inch hex socket drive, allowing torque to be applied with a standard hex key. The screw measures 7\/16-20 thread size by 1-1\/4 inches in overall length and is fully threaded. Manufactured from alloy steel with a black oxide finish, it delivers solid shear strength and corrosion resistance suitable for industrial, mechanical, and structural use. Machinists, maintenance technicians, and fabricators typically install this fastener.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for applications where the fastener head must sit flush with or below the mating surface. Common use cases include machine frames, jigs, fixtures, tooling plates, and mechanical assemblies where a low-profile head is required. The black oxide finish reduces light reflection and provides moderate corrosion protection in dry to mildly humid environments. The UNF thread standard and ASME\/ANSI B18.3 and ASTM F835 compliance make it a recognized specification fastener for industrial and OEM applications.\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\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for precise torque application with a hex key\u003c\/li\u003e\n  \u003cli\u003eFully threaded 7\/16-20 UNF shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for reduced reflectivity and moderate corrosion protection\u003c\/li\u003e\n  \u003cli\u003eMeets 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 a standard UNF replacement or OEM-spec fastener for countersunk socket cap applications requiring a 7\/16-20 thread and 82-degree flat head seating angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/4-inch hex key or socket driver. Ensure the mating material is drilled and countersunk to the correct 82-degree angle before installation. Follow ASME torque guidelines for alloy steel fasteners of this thread size and do not exceed the rated torque to avoid galling or thread damage. Inspect the countersink bore and thread engagement before final torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/4 inches (overall length)\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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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 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: 721228PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692098650418,"sku":"721228PR","price":1470.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_9ffea2b9-585f-445a-a539-8748320e2819.jpg?v=1788293069","url":"https:\/\/voomisupply.com\/products\/value-collection-721228pr-flat-socket-cap-screw-7-16-20","provider":"Voomi Supply","version":"1.0","type":"link"}
