It features an 82-degree flat head driven by a 5\/16-inch hex socket, making it compatible with standard Allen wrenches and hex key sets. The screw is fully threaded with a 1\/2-20 UNF thread and measures 1-1\/2 inches in overall length. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in precision assemblies, jigs, fixtures, and machine components where a low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for industrial and mechanical applications where UNF fine-thread engagement is needed for tighter tolerances or vibration resistance. The 82-degree flat head seats flush with the mating surface when installed in a properly countersunk hole. It is appropriate for use in metalworking, manufacturing equipment, and general mechanical assemblies. The black oxide finish reduces light reflection and provides a degree of surface protection in dry or mildly humid indoor environments. This fastener meets ASME\/ANSI B18.3 and ASTM F835 standards.\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\u003e5\/16-inch hex socket drive accepts standard Allen wrenches\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF fully threaded shank for fine-thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for surface protection and reduced glare\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 an OEM-style replacement or standard fastener for mechanical assemblies requiring a 1\/2-20 UNF flat socket cap screw with an 82-degree countersink angle and a 1-1\/2-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified maintenance technicians. The mating component must be drilled and countersunk to an 82-degree angle to achieve a flush seating surface. Use a calibrated torque wrench with a 5\/16-inch hex bit to drive the fastener to the torque specification required by the assembly drawing. De-energize and lock out any equipment before replacing fasteners in live mechanical systems.\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\u003eLength\u003c\/strong\u003e: 1-1\/2 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\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: 0.09 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: 211313PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695785771314,"sku":"211313PR","price":1460.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a8f9c12776b50e3d966f26b841c4079.jpg?v=1788338226","url":"https:\/\/voomisupply.com\/products\/value-collection-211313pr-flat-socket-cap-screw-1-2-20","provider":"Voomi Supply","version":"1.0","type":"link"}
