Manufactured from alloy steel with a zinc-plated finish for corrosion resistance, this screw features a 5\/16-18 UNC thread size and a 5\/8 inch length under the head. The 1\/4 inch hex drive accepts a standard hex key or Allen wrench for installation in confined or recessed spaces where a conventional wrench cannot reach. This fastener meets ASME B18.8 and ASTM A574 standards, making it appropriate for load-bearing and precision mechanical work across industrial, HVAC, plumbing, and electrical panel applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in light to medium-duty mechanical assemblies, equipment enclosures, and service work where a low-profile socket head is required. The 5\/16-18 UNC coarse thread provides reliable engagement in tapped steel, cast iron, or aluminum components. Contractors, millwrights, and field service technicians routinely use this fastener when reassembling equipment panels, mounting brackets, or securing components within mechanical systems. It is sold in a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 5\/8 inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex socket drive for use with standard hex keys in tight spaces\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion protection in indoor and moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex socket cap screw compatible with any tapped hole or threaded insert meeting ASME B18.8 dimensional specifications for this thread size and drive type.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/4 inch hex key or T-handle Allen wrench rated for socket cap screws. Ensure the receiving threads are clean and free of debris before installation. When used in electrical enclosures or equipment panels, de-energize all circuits and follow applicable NEC or OSHA lockout\/tagout procedures before beginning work. Do not exceed the torque rating appropriate for 5\/16-18 alloy steel fasteners as specified by the equipment manufacturer or applicable engineering standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.625 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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.8 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 872197PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713774256434,"sku":"872197PR","price":2051.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef6720c757834135ee8af4c7b0630447_56a06339-8ab3-44ec-8d37-d79983cda728.jpg?v=1788495125","url":"https:\/\/voomisupply.com\/products\/value-collection-872197pr-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
