Manufactured from alloy steel with a black oxide finish, this screw provides corrosion resistance and a clean appearance suited to exposed or semi-exposed hardware applications. The 5\/8-11 UNC thread and 1-3\/4 inch length under head make it appropriate for medium-to-heavy load connections in fabricated steel structures, machinery, and equipment enclosures. Hardness is rated at 36-43 HRC, confirming suitability for demanding structural and mechanical service. It is driven with a 3\/8 inch hex socket.\u003c\/p\u003e\n\u003cp\u003eThis fastener is commonly used in industrial machinery, metal fabrication, and structural steel applications where a conventional hex head would interfere with adjacent components or clearance is limited. The button head profile keeps fastener projection minimal while still delivering the clamping force of an alloy steel cap screw. Machinists, millwrights, fabricators, and maintenance technicians working on equipment frames, guards, brackets, and panels are the typical installers. It meets ANSI\/ASME B18.3 and ASTM F835 standards, making it appropriate for applications that require documented fastener compliance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile reduces fastener projection in clearance-limited assemblies\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated 36-43 HRC for high-strength service\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and a low-glare appearance\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC Thread Fit Class 3A for consistent, close-tolerance engagement\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, fully threaded\u003c\/li\u003e\n  \u003cli\u003eComplies with 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 5\/8-11 UNC button socket cap screw for use in any tapped hole or threaded insert conforming to UNC Class 3B specifications in industrial, mechanical, or structural applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/8 inch hex socket or ball-end hex key driver. Confirm the mating threaded hole is clean and free of debris before driving. Apply thread lubricant or anti-seize compound when working with tapped steel in high-temperature or corrosive environments, following the equipment manufacturer or applicable industry torque specifications for the fastener size and grade. De-energize and lock out any equipment before accessing fasteners on live machinery per applicable OSHA and equipment service procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 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\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.331 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 0.01 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: 701221BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700113506610,"sku":"701221BR","price":35.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8ac0a140d736b326fa7994dd3d945bb.jpg?v=1788386188","url":"https:\/\/voomisupply.com\/products\/value-collection-701221br-button-socket-cap-screw-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
