Manufactured from alloy steel with a black oxide finish, it carries a thread size of 5\/16-24 UNF and a length under the head of 0.75 inches. The button head style reduces the overall fastener profile compared to a standard socket cap, making it suitable for confined assemblies. Drive engagement is through a 3\/16-inch hex socket. Hardness is rated at 36-43 HRC, consistent with ANSI\/ASME B18.3 and ASTM F835 standards. Licensed tradespeople and precision assembly technicians regularly specify this screw where flush or recessed fastening is required.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in mechanical assemblies, machine guarding, tooling fixtures, and structural sub-assemblies where a fine-thread UNF engagement is preferred for vibration resistance or precise clamping load control. The black oxide coating provides moderate corrosion resistance in indoor or protected environments. It is fully threaded along the 0.75-inch shank length and uses a right-hand thread direction. Minimum order quantity is 100 pieces, sold individually per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile reduces protrusion in tight or surface-sensitive assemblies\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated at 36-43 HRC for reliable shear and clamping strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion resistance in indoor environments\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF fine thread with Class 3A thread fit for precise engagement\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along 0.75-inch length under head\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF button socket cap screw per ANSI\/ASME B18.3 and ASTM F835, suitable for use in any 5\/16-24 threaded hole requiring a low-profile hex socket drive fastener in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a 3\/16-inch hex key or socket driver; do not use an undersized driver, as this risks cam-out and head damage. Ensure the mating threaded hole is clean and free of debris before engagement. Apply thread lubricant or thread-locking compound according to the assembly specification. Follow applicable torque guidelines for 5\/16-24 alloy steel fasteners as specified by the equipment OEM or relevant ASME standards.\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\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\u003eLength Under Head\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.166 inches\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\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: 36-43 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3, ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\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: 201149PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699879870770,"sku":"201149PR","price":2427.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afb9ad14761d0ac055b125d11f7c94e7.jpg?v=1788382470","url":"https:\/\/voomisupply.com\/products\/value-collection-201149pr-button-socket-cap-screw-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
