It features a 5\/8-18 UNF thread size with a 2-3\/4 inch length under head and is partially threaded for precise clamping in controlled-depth bores. The 1\/2 inch hex drive is compatible with standard hex keys and socket drive tools. Constructed from alloy steel with a black oxide finish, this screw delivers corrosion resistance and meets ASME\/ANSI B18.3 and ASTM A574 standards. Machinists, millwrights, and maintenance technicians regularly specify this fastener type for structural and load-bearing connections.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in industrial machinery, fixtures, die sets, and precision equipment where fine-thread UNF engagement is required for vibration resistance and torque retention. The partially threaded shank provides a smooth bearing surface in clearance holes, making it appropriate for assemblies requiring tight positional tolerances. Minimum order quantity is 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-18 UNF fine thread for high vibration resistance and precise torque control\u003c\/li\u003e\n\u003cli\u003e2-3\/4 inch length under head with partial threading for clearance-hole assemblies\u003c\/li\u003e\n\u003cli\u003e1\/2 inch hex socket drive compatible with standard hex keys and drive tools\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion protection and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 5\/8-18 UNF partially threaded fastener with a 1\/2 inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a 1\/2 inch hex key or socket driver. Ensure mating threaded holes are clean and free of debris before installation. Follow applicable torque specifications from your engineering drawings or fastener reference tables for ASTM A574 alloy steel cap screws. De-energize and lock out any equipment before performing fastener service on live machinery per OSHA lockout\/tagout procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/4 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\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: -48548-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703615324466,"sku":"-48548-6","price":42.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_54c2fc33-f7bc-4000-8261-443c0543baec.jpg?v=1788417623","url":"https:\/\/voomisupply.com\/products\/value-collection-48548-6-hex-socket-cap-screw-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
