Manufactured from alloy steel with a black oxide coating, this fastener measures 9 inches in length under the head and features a 3\/4-10 UNC thread with partial threading along the shank. The 5\/8-inch hex drive accepts standard hex keys and Allen-style drivers. The black oxide finish provides a baseline level of corrosion resistance while reducing light reflection in precision assemblies. This screw meets ASME B18.3 and ASTM A574 standards, confirming its suitability for structural and mechanical fastening tasks requiring verified tensile strength.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for heavy equipment assembly, machine frames, structural fixturing, and other industrial installations where a large-diameter, partially threaded socket cap screw is required. The 3\/4-10 UNC coarse thread is well suited for applications involving thick or tapped steel members. Electricians, millwrights, mechanical contractors, and equipment maintenance technicians commonly use this size when assembling or repairing industrial machinery and support structures. Its alloy steel construction makes it appropriate for high-load environments where standard carbon steel fasteners may not meet tensile requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for corrosion resistance and reduced surface reflection\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC coarse thread for reliable engagement in tapped steel\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides clamp load control in thick assemblies\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards for socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimensioned ASME B18.3 hex socket cap screw for use in any tapped or threaded hole accepting a 3\/4-10 UNC fastener with a 9-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician using a properly sized 5\/8-inch hex key or socket driver. Confirm that the mating tapped hole is clean, properly threaded to 3\/4-10 UNC, and free of debris before driving the fastener. Do not exceed the recommended torque for alloy steel cap screws of this diameter as specified by ASME or the equipment manufacturer. Apply thread lubricant or anti-seize compound where environmental conditions may cause galling or corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 9 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: 5\/8 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\u003eWeight\u003c\/strong\u003e: 1.22 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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 720003354\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51744028131634,"sku":"720003354","price":80.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bfab823152d7ac26975478f8323e7e3b.jpg?v=1788853184","url":"https:\/\/voomisupply.com\/products\/holo-krome-720003354-hex-socket-cap-screw-3-4-10-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
