Sized at 5\/8-11 UNC with a 3.5-inch length under head, this fastener is driven with a 1\/2-inch hex key. Constructed from alloy steel with a black oxide coating, it delivers corrosion resistance and a non-reflective finish suited for demanding environments. It meets ASME B18.3 and ASTM A574 standards, confirming its suitability for critical load-bearing connections where material strength and dimensional accuracy are required.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in heavy-duty mechanical assemblies, machinery frames, tooling fixtures, and structural components where a recessed drive and high clamping force are needed. The partial threading allows the shank to act as a locating feature in precision fits. Machinists, millwrights, maintenance technicians, and mechanical contractors regularly specify this type of fastener for equipment assembly, fabrication, and repair work across industrial and commercial settings.\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 inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head provides substantial grip length for thick-stack assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for precise hole location and shear resistance\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive socket for positive torque transfer with standard hex keys or T-handles\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 reduces surface glare\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw for use in any 5\/8-11 UNC tapped hole application requiring a partially threaded alloy steel fastener with a 1\/2-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified machinists or mechanical technicians using a calibrated torque wrench and a properly sized 1\/2-inch hex key or socket bit. Ensure the mating tapped hole is clean, free of debris, and cut to correct depth before installation. Apply a thread lubricant or anti-seize compound appropriate for the service environment to achieve accurate clamp load. Power down and de-energize any equipment before accessing fastener locations on live machinery.\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: 3.5 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\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 72284\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51743929139506,"sku":"72284","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db4f3347f5b1ff2424c1b79ecf78720e.jpg?v=1788851454","url":"https:\/\/voomisupply.com\/products\/holo-krome-72284-hex-socket-cap-screw-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
