This fastener features a 5\/16-18 UNC thread size and a 7\/8 inch length under head, providing reliable clamping force in tight assemblies where a hex key is the preferred drive tool. The 1\/4 inch hex drive socket head allows for high torque application in confined spaces. Constructed from alloy steel with a black oxide finish coating, this screw offers solid mechanical strength and a degree of corrosion resistance in controlled environments. Installation is handled by mechanical trades, maintenance technicians, and assembly professionals.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for general industrial fastening, machine assembly, jig and fixture construction, and equipment maintenance. The fully threaded shank engages the entire fastened length, making it appropriate for through-hole and threaded insert applications. The black oxide coating provides mild surface protection and reduces light reflection, which is useful in precision and optical assembly contexts. Sold individually with a minimum order quantity of 50 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread size for standard unified coarse thread engagement\u003c\/li\u003e\n\u003cli\u003e7\/8 inch length under head, fully threaded shank\u003c\/li\u003e\n\u003cli\u003e1\/4 inch hex socket drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish coating for surface protection and low reflectivity\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fastener for any assembly requiring a 5\/16-18 UNC fully threaded hex socket cap screw with a 7\/8 inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a 1\/4 inch hex key or hex socket driver. Ensure the mating threaded hole or nut is clean and free of debris before installation. Follow applicable mechanical assembly standards and equipment manufacturer torque guidelines for 5\/16-18 UNC fasteners. Do not use damaged threads or force-thread into misaligned holes, as this may compromise clamp load and joint integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 7\/8 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: 1\/4 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: 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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\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: -33618-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717847122226,"sku":"-33618-1","price":17.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53a01b4a7909a29308541bcb30f1c4fa.jpg?v=1788546632","url":"https:\/\/voomisupply.com\/products\/value-collection-33618-1-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
