It features a 1\/2-20 UNF thread with an overall length of 2.25 inches and is fully threaded along its entire length. The 82-degree flat head seats flush with the mating surface, while the 5\/16-inch hex socket drive accepts a standard hex key for installation and removal. Constructed from alloy steel with a black oxide finish, this screw is suited for moderate corrosion resistance and reduced light reflection in industrial and mechanical assemblies. Machinists, millwrights, and maintenance mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is used in machine assemblies, fixture plates, jigs, tooling, and structural components where a flush fastener surface is required. The fully threaded 1\/2-20 UNF shank allows full thread engagement across a range of material thicknesses. Black oxide finish is appropriate for interior or lightly protected environments. The screw conforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards, making it a recognized fit for precision mechanical applications in both light manufacturing and maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush countersunk installations\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for secure torque application with a standard hex key\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF fully threaded shank, 2.25 inches overall length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength in demanding assemblies\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare appearance\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 flat socket cap screw for use in any tapped or through-hole application requiring a 1\/2-20 thread pitch and an 82-degree countersunk seating surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance mechanics using a 5\/16-inch hex key or hex bit driver. Ensure the mating countersink is machined to an 82-degree included angle to achieve proper head seating. De-energize and lock out any machinery before fastener service in accordance with applicable OSHA lockout\/tagout procedures. Do not substitute an incorrect hex key size, as rounding the socket drive can make removal difficult.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\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\u003eFull or Partial Threading\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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and 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: 721254PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701606220082,"sku":"721254PR","price":1595.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_e0d48061-733b-4d42-98ae-0a08d7b273dc.jpg?v=1788402358","url":"https:\/\/voomisupply.com\/products\/value-collection-721254pr-flat-socket-cap-screw-1-2-20","provider":"Voomi Supply","version":"1.0","type":"link"}
