It features a 3\/4-16 UNF thread size with 6-1\/2 inches of length under the head and partial threading along the shank. The drive is a 5\/8-inch hex socket, requiring a standard hex key or Allen drive tool. Constructed from alloy steel with a black oxide finish, this screw offers solid corrosion resistance and surface hardness for demanding environments. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming dimensional accuracy and mechanical performance.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machinery assembly, fixture mounting, and structural fastening applications where a recessed drive and high clamping force are required. The partially threaded shank allows for precise clamping without thread engagement through the full grip length, making it a common choice in precision mechanical assemblies, jigs, and equipment frames. It is typically installed by machinists, millwrights, maintenance technicians, and mechanical contractors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF thread for fine-pitch, high-strength engagement\u003c\/li\u003e\n  \u003cli\u003e6-1\/2 inches length under head with partial threading for controlled clamp load\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex socket drive for high-torque installation with standard tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced glare\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI 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 fastener for applications requiring a 3\/4-16 UNF hex socket cap screw with a 6-1\/2-inch length under head and 5\/8-inch drive, conforming to ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician using a calibrated torque wrench and the correct 5\/8-inch hex key or drive bit. Always ensure the mating threaded hole is clean, properly tapped to 3\/4-16 UNF, and free of debris before installation. De-energize and lock out any equipment before fastener service per applicable safety procedures. Do not use impact tools without verifying torque compliance with the assembly specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partial\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 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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\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: 581747BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721719349554,"sku":"581747BR","price":23.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b7e603e9009e8eb02171180fae9ce24.jpg?v=1788579855","url":"https:\/\/voomisupply.com\/products\/value-collection-581747br-hex-socket-cap-screw-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
