It features an 82-degree flat head and a 3\/16-inch hex socket drive, accepting a standard hex key for installation. The screw is fully threaded along its 1-3\/4-inch overall length with a 5\/16-24 UNF thread form, providing fine-thread engagement suited to close-tolerance assemblies. Manufactured from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance in dry or lightly oiled environments. Machinists, millwrights, and mechanical assembly technicians are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis fastener is appropriate for use in precision mechanical assemblies, machine components, and structural fixtures where the fastener head must sit flush with or below the mating surface. The fine 5\/16-24 UNF thread pitch makes it a common choice in applications involving thin materials, vibration-prone assemblies, or components that require frequent disassembly and re-engagement without thread wear. It is sold individually but requires a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile allows flush or countersunk installation in mating surfaces\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for standard Allen key or hex bit installation\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF fine-thread form for precise engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1-3\/4-inch overall length maximizes thread engagement across the full shank\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 provides a low-reflectance appearance with light corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for mechanical assemblies requiring a countersunk socket cap screw with a 5\/16-24 UNF thread and 1-3\/4-inch overall length, conforming to ASME\/ANSI B18.3 and ASTM F835 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/16-inch hex key or hex-bit driver; ensure the key is fully seated before applying torque to avoid rounding the socket. Verify the mating material has an 82-degree countersink to match the flat head angle before installing. De-energize or lock out any equipment before fastener replacement on machinery. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific 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\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-3\/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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 0.01 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: 721186PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708247441714,"sku":"721186PR","price":7804.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_f13f5f0b-8bbb-4ccd-bc4b-e831f4332ea7.jpg?v=1788445083","url":"https:\/\/voomisupply.com\/products\/value-collection-721186pr-flat-socket-cap-screw-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
