This screw features a 5\/8-11 UNC thread size and a 2.5-inch length under the head, with partial threading along the shank. It is manufactured from alloy steel with a zinc-plated finish that provides corrosion resistance in standard service environments. The 1\/2-inch hex drive socket is engaged using a standard hex key or Allen wrench. This fastener meets ASTM B695 standards and is suited for installation by millwrights, machinists, maintenance technicians, and general tradespeople working with threaded fastener assemblies.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in residential and commercial mechanical assemblies where a recessed drive fastener is required for flush or countersunk installation. Typical applications include machine frames, equipment enclosures, jigs, fixtures, and structural brackets. The partial thread design provides a strong clamping grip and is preferred when fastening materials of varying thickness or when a shoulder bearing surface is needed. The zinc-plated alloy steel construction makes it suitable for dry to mildly humid indoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread size for compatibility with standard unified coarse thread nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e2.5 inches length under head with partial threading along the shank\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for use with standard hex keys or Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish meets ASTM B695 for corrosion protection in standard indoor environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 UNC hex socket cap screw suitable for use in any application requiring a partially threaded alloy steel socket head fastener with a 1\/2-inch hex drive and 2.5-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 1\/2-inch hex key or Allen wrench; ensure the mating tapped hole or nut is clean and free of debris before driving. Power down and de-energize any equipment before servicing fasteners on electrical or mechanical assemblies. Do not over-torque alloy steel fasteners in tapped aluminum or cast iron holes, as thread stripping can occur. Follow applicable industry torque standards for the fastener grade and material combination in use.\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: 2.5 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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B695\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 837421BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714727412018,"sku":"837421BR","price":33.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef7433c0f39753bd4c25746d054998c7.jpg?v=1788505521","url":"https:\/\/voomisupply.com\/products\/value-collection-837421br-hex-socket-cap-screw-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
