Manufactured from alloy steel with a black oxide coating, this screw features a 5\/16-24 UNF thread and measures 3\/8 inches under the head. The button head profile reduces the overall installed height compared to a standard socket cap head. Drive engagement is provided by a 3\/16 hex socket. This fastener meets ANSI\/ASME B18.3 and ASTM F835 standards and carries a hardness rating of 36 to 43 HRC. It is a fully threaded, right-hand thread fastener suited for precision mechanical assemblies in industrial and manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in machine tool fixtures, equipment enclosures, jigs, and mechanical assemblies where a flush or near-flush fastener head is required. The fine 24-thread-per-inch UNF pitch provides strong thread engagement and resistance to vibration loosening, making it well suited for metal-to-metal connections in tight tolerances. The black oxide finish offers mild corrosion resistance and a low-reflectance surface. This fastener is typically installed by machinists, millwrights, and maintenance mechanics working in manufacturing and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile provides a low-profile, rounded appearance with reduced installed height\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF fully threaded for maximum thread engagement in short-grip applications\u003c\/li\u003e\n  \u003cli\u003e3\/16 hex socket drive for use with standard hex keys and ball-end drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 36 to 43 HRC hardness for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for mild corrosion resistance and reduced surface reflectance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or replacement fastener for mechanical assemblies requiring a 5\/16-24 UNF button socket cap screw per ANSI\/ASME 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 ball-end driver; ensure the socket is fully seated before applying torque to avoid rounding the drive. Thread fit class 3A indicates a standard close-tolerance fit — verify the mating tapped hole is compatible before installation. Black oxide screws are not rated for outdoor or high-humidity environments without additional lubrication or sealant. This fastener carries a minimum order quantity of 100 pieces; confirm quantity requirements before ordering.\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 Under Head\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\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\u003eHead Height\u003c\/strong\u003e: 0.1660 inches\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\u003eHardness\u003c\/strong\u003e: 36 to 43 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME 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: 201143PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694944059698,"sku":"201143PR","price":1941.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b46f0e5dde6875278d208903b69877d.jpg?v=1788329862","url":"https:\/\/voomisupply.com\/products\/value-collection-201143pr-button-socket-cap-screw-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
