Built from alloy steel with a black oxide finish, this screw features an 82-degree flat head and a 3\/16-inch hex socket drive. The 5\/16-18 UNC thread is fully threaded along the 2-inch overall length, making it suitable for through-bolting in metal, structural, and mechanical assemblies. It meets ASME\/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and maintenance technicians working in industrial and commercial settings regularly install this fastener type.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is well-suited for applications where a raised head would interfere with mating surfaces or moving components. Common uses include machine frames, fixtures, tooling plates, and equipment panels where a flush seating surface is required. The hex socket drive allows access in recessed or tight clearance locations where a standard wrench cannot reach. The black oxide finish provides mild corrosion resistance and reduces surface glare in precision assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head profile for countersunk, flush-mount installations\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive for use with standard Allen or hex key tools\u003c\/li\u003e\n\u003cli\u003eFully threaded 5\/16-18 UNC along the full 2-inch overall length\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength in demanding applications\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and a low-glare surface\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-service flat socket cap screw for machinery, fixtures, and structural assemblies requiring a 5\/16-18 UNC fully threaded fastener with an 82-degree countersunk head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a 3\/16-inch hex key or Allen driver; ensure the driver is fully seated before applying torque to avoid cam-out and socket damage. Countersink the receiving hole to 82 degrees to achieve a proper flush seat. Power down and de-energize any equipment before fastener replacement on live machinery. Follow applicable ASME and facility maintenance codes for fastener installation in structural or load-bearing applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 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: 3\/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\u003eWeight\u003c\/strong\u003e: 0.044 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 211171P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715995631922,"sku":"211171P","price":8683.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d1316c25837a2a9743a8c2afb1a4352.jpg?v=1788520755","url":"https:\/\/voomisupply.com\/products\/value-collection-211171p-flat-socket-cap-screw-5-16-18-x-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
