Featuring an 82-degree flat head and a 3\/16-inch hex socket drive, this fastener accepts a standard hex key for reliable torque transfer. It is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection. The 5\/16-24 UNF thread specification indicates a fine-thread pitch suited to applications demanding greater thread engagement and vibration resistance. This screw measures 2.5 inches in overall length and is partially threaded. It is used by machinists, millwrights, and mechanical assemblers across industrial and manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in machine assemblies, jigs and fixtures, tooling plates, and structural components where a countersunk, low-profile head is required. The fine thread series makes it appropriate for metal-to-metal connections where thread stripping resistance and precise clamping force are priorities. It is commonly installed in ferrous and high-strength base materials where a clean surface finish after installation is necessary. Partially threaded construction allows for clamping of stacked components with a shank section that passes through a clearance hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive compatible with standard hex keys and bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF fine-thread for tight thread engagement in metal assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows controlled clamping across clearance holes\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-use flat socket cap screw for applications requiring a 5\/16-24 UNF fine-thread, 82-degree countersunk fastener in alloy steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or mechanical assemblers using a 3\/16-inch hex key or socket driver. Ensure the mating countersink is machined to an 82-degree included angle to achieve full head seating. De-energize and lock out any equipment before installing or removing fasteners in live machinery per applicable OSHA and equipment-specific procedures. Do not substitute a coarse-thread fastener in a fine-thread tapped hole.\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: 2.5 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: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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\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: 721189PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696600056114,"sku":"721189PR","price":896.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_229f5dcc-6531-4794-9eee-b27cb1ed850b.jpg?v=1788344321","url":"https:\/\/voomisupply.com\/products\/value-collection-721189pr-flat-socket-cap-screw-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
