The 82-degree flat head seats into a matching countersunk hole, keeping the fastener face level with or below the workpiece surface. Driven by a 7\/32-inch hex socket, it is manufactured from alloy steel with a black oxide finish for moderate corrosion resistance. The 3\/8-24 UNF thread is partially threaded over the 2-3\/4-inch overall length, providing a grip length suited for clamping two or more components together. Machinists, maintenance technicians, and fabricators typically install this screw in precision assemblies where a protruding head is not acceptable.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in mechanical assemblies, tooling fixtures, machine frames, and structural joints where a countersunk fastener is required. The 3\/8-24 UNF (Unified National Fine) thread pitch is common in high-strength or vibration-prone applications where fine threads provide better clamp load retention. The black oxide finish is appropriate for indoor or lightly oiled environments. It conforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head profile for flush or countersunk installations\u003c\/li\u003e\n\u003cli\u003e7\/32-inch hex socket drive for standard Allen key or hex bit tools\u003c\/li\u003e\n\u003cli\u003e3\/8-24 UNF partially threaded shank over 2-3\/4-inch overall length\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM F835 and ASME\/ANSI B18.3 standards\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eInch measurement system; overall length measurement convention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series flat socket cap screw conforming to ASME\/ANSI B18.3 and ASTM F835, suitable for use in any application accepting a 3\/8-24 UNF countersunk hex socket fastener of 2-3\/4-inch overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 7\/32-inch hex key or hex socket bit torqued to the specification appropriate for the grade and joint material. Power down or de-energize any equipment before fastener service. Ensure the mating countersink is machined to an 82-degree included angle to achieve full head seating. Do not overtighten in soft or tapped through-holes; verify thread engagement length meets design requirements before final torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2-3\/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: 7\/32 inches\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 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 721231PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710794301746,"sku":"721231PR","price":776.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_0fdbd6c1-b55a-4d44-92a9-27931939c4c0.jpg?v=1788470655","url":"https:\/\/voomisupply.com\/products\/value-collection-721231pr-flat-socket-cap-screw-3-8-24","provider":"Voomi Supply","version":"1.0","type":"link"}
