It features a 5\/16-18 UNC thread size with a 2-inch length under the head and is partially threaded along its shank. The 1\/4-inch hex drive allows for use with standard hex keys and socket wrenches. Constructed from alloy steel with a zinc-plated finish, this fastener resists corrosion while delivering the tensile strength required in demanding industrial and commercial applications. It is sold individually but requires a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for general mechanical assembly, equipment fabrication, and maintenance applications where a recessed hex drive is preferred for torque control and a clean fastener head profile. The partially threaded shank is ideal for applications requiring precise clamping force between mating components. It is commonly used in manufacturing, machinery, HVAC equipment assembly, and structural metalwork by maintenance technicians, machinists, and fabricators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head with partial threading for controlled clamping\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for use with hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME B18.8 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in typical indoor environments\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for any application requiring a 5\/16-18 UNC partially threaded hex socket cap screw with a 2-inch length under head, conforming to ASME B18.8 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/4-inch hex key or socket driver. Verify that the mating tapped hole is clean and properly threaded to 5\/16-18 UNC before installation. Always torque fasteners to the assembly manufacturer's specification — do not substitute a torque value not provided for this specific joint. Follow all applicable mechanical codes and safety procedures when working on equipment that must be de-energized or depressurized before fastener service.\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: 2 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\/4 inch\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 \/ ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 872211PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720136425778,"sku":"872211PR","price":7788.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef6720c757834135ee8af4c7b0630447_896081ed-30f2-4ad2-b4c7-766663b84898.jpg?v=1788560979","url":"https:\/\/voomisupply.com\/products\/value-collection-872211pr-hex-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
