Machined from alloy steel with a black oxide finish, this fastener meets ANSI\/ASME B18.3 and ASTM F835 standards. The low-profile button head reduces interference in tight clearance situations while the hex socket drive allows precise torque application with standard tooling. A hardness rating of 36-43 HRC provides the clamping strength required in demanding industrial and trade environments. Fully threaded along its 1-1\/4 inch length under head, this screw is sold in a package quantity of 25.\u003c\/p\u003e\n\u003cp\u003eThis button socket cap screw is suited for applications where a flush or near-flush head profile is needed alongside high tensile strength. Common installation scenarios include machine frames, jigs, guard assemblies, and industrial equipment panels. The UNC thread form and Class 3A thread fit ensure consistent engagement in standard tapped holes. Machinists, millwrights, and maintenance technicians working in manufacturing, HVAC equipment assembly, and mechanical contracting environments will find this fastener appropriate for a range of general-purpose bolted joint requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction with 36-43 HRC hardness for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eLow-profile button head minimizes protrusion in clearance-critical assemblies\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive compatible with standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/8-11 UNC Class 3A right-hand thread for consistent fit in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets 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 for use in standard 5\/8-11 UNC tapped holes.

Verify that the mating tapped hole meets 5\/8-11 UNC Class 3A tolerances before installation. Ensure mating surfaces are clean and free of debris to achieve proper seating of the button head. Follow applicable ASME or project-specific torque specifications for 5\/8-11 alloy steel fasteners when determining final torque values.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.3310 inches\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\u003eThread Standard\u003c\/strong\u003e: UNC\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\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\u003ePackage Quantity\u003c\/strong\u003e: 25\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: -40889-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691300356402,"sku":"-40889-1","price":50.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_8f2d78c0-405c-452e-9e33-ba2e8e301dc6.jpg?v=1788282919","url":"https:\/\/voomisupply.com\/products\/value-collection-40889-1-button-socket-cap-screw-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
