It features a 5\/8-11 UNC thread, a 2.5-inch length under head, and a partially threaded shank. The 1\/2-inch hex socket drive accepts standard hex keys and torque tools for precise installation. Manufactured from alloy steel with a black oxide finish, this screw delivers corrosion resistance alongside the tensile strength required for demanding service environments. It meets ASME B18.3 and ASTM A574 standards, making it a recognized choice for engineering and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in industrial machinery, fabricated steel structures, tooling fixtures, and equipment frames where a recessed drive fastener is required. The 5\/8-11 UNC coarse thread pattern provides strong thread engagement in standard tapped holes and is compatible with nuts and inserts machined to UNC specifications. The black oxide coating reduces surface friction during installation and provides mild corrosion protection in dry or lightly oiled environments. Licensed tradespeople, millwrights, industrial mechanics, and maintenance technicians commonly install this fastener type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head with partial threading for shear-load applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for use with Allen keys and torque wrenches\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced galling\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-spec fastener for any application requiring a 5\/8-11 UNC hex socket cap screw conforming to ASME B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by industrial mechanics, millwrights, or maintenance technicians using a calibrated torque wrench with a 1\/2-inch hex bit. De-energize and lock out all equipment before fastener installation or removal per applicable OSHA and facility lockout\/tagout procedures. Thread the screw into a clean, properly tapped hole and tighten to the torque value specified in the equipment manufacturer's documentation. Do not substitute thread-locking compounds or coatings not approved for the application, as this may affect clamp load.\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\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\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\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM A574\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72276\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51739897397554,"sku":"72276","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41a86773fa2100025de261f1072f8bb4.jpg?v=1788820174","url":"https:\/\/voomisupply.com\/products\/holo-krome-72276-hex-socket-cap-screw-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
