Built from alloy steel with a black oxide finish, this screw meets ASTM A574 standards, making it suitable for demanding clamping and structural fastening tasks. The 5\/16-18 UNC thread size and 3-inch length under head accommodate a range of material thicknesses. Drive engagement is achieved with a 7\/32-inch hex key. The black oxide coating provides moderate corrosion resistance and reduces light reflection in precision assemblies. Installation is straightforward for machinists, maintenance technicians, and mechanical contractors working in both shop and field environments.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in general mechanical assembly, equipment maintenance, and fabrication applications where a recessed drive and high clamp load are required. The partially threaded shank provides a smooth bearing surface through clearance holes, making it well suited for bolted joints where shear load distribution matters. It is commonly installed in metal-to-metal fastening scenarios across industrial, HVAC equipment, and structural sub-assembly work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for standard inch-series fastening\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading for shear-load applications\u003c\/li\u003e\n  \u003cli\u003e7\/32-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength cap screw standard\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides moderate corrosion resistance and a low-glare finish\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 10 units per order\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 application requiring ASTM A574 alloy steel fasteners with a 3-inch length under head and partial threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or mechanical technicians using a 7\/32-inch hex key or socket bit. De-energize and lock out any equipment before fastener replacement or assembly work. Apply fastener torque per the joint design specification for 5\/16-18 ASTM A574 grade fasteners. Inspect threads for damage before installation and do not use an impact driver without a torque-limiting attachment.\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: 3 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: 7\/32 inches\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: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: 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: 307120PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720960901426,"sku":"307120PR","price":551.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3d4393290d1151337a0e6cc1706718c_5bbf23ea-612f-46f5-9a33-9df054fb0aae.jpg?v=1788571509","url":"https:\/\/voomisupply.com\/products\/value-collection-307120pr-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
