Manufactured from alloy steel with a black oxide finish, this screw measures 5\/16-24 (UNF) in thread size and 3\/4 inches in overall length. The 82-degree flat head seats flush with or below the work surface, and the 3\/16-inch hex socket drive allows installation with a standard hex key. It is fully threaded along its length, providing consistent clamping force across the full engagement zone. Machinists, maintenance technicians, and mechanical assembly professionals typically install this fastener in precision equipment, tooling fixtures, and structural components.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for both light industrial and mechanical assembly environments where a low-profile, countersunk fastener is needed. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it a common choice for tooling plates, machine guarding, and interior mechanical assemblies. The UNF (Unified Fine) thread standard offers tighter thread engagement compared to coarse-pitch alternatives, which is advantageous in thin-material applications or where vibration resistance is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush or countersunk installation\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive compatible with standard hex keys and allen wrenches\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/4-inch length for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-reflectance appearance\u003c\/li\u003e\n  \u003cli\u003eUNF thread standard (5\/16-24) for fine-pitch applications requiring tight tolerance fits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit fastener for applications requiring a 5\/16-24 UNF fully threaded flat socket cap screw per ASME\/ANSI B18.3 and ASTM F835 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16-inch hex key or T-handle allen wrench; ensure the mating countersink is machined to an 82-degree included angle for proper head seating. Verify the tapped hole meets UNF thread class requirements before installation. Do not exceed the rated tightening torque for the fastener grade and material combination being used. Always degrease mating surfaces and inspect threads for damage before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/4 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\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Black Oxide\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: 0.02 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: 211181PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699958055218,"sku":"211181PR","price":2688.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5683533759afd511d72696692609751.jpg?v=1788384079","url":"https:\/\/voomisupply.com\/products\/value-collection-211181pr-flat-socket-cap-screw-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
