It features a 3\/8-16 UNC thread size and measures 4 inches under the head, making it suited for medium-to-heavy-duty assemblies. Constructed from 18-8 stainless steel, it provides solid corrosion resistance in wet, chemical-exposure, or outdoor environments. The 5\/16-inch hex drive accepts a standard Allen key or hex bit driver for secure installation. This fastener is commonly specified by maintenance technicians, pipefitters, millwrights, and equipment fabricators working in commercial and industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in structural, mechanical, and equipment-mounting applications where a clean hex socket drive is preferred over external hex or Phillips styles. The 3\/8-16 UNC coarse thread makes it straightforward to thread into tapped steel, aluminum, or stainless components. Typical install scenarios include machine frames, brackets, pump housings, flanges, and enclosures. The 18-8 stainless steel construction makes it a reliable choice in food-service, marine-adjacent, and outdoor equipment environments where carbon steel fasteners would corrode.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for compatibility with standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head for deep engagement in thick stock or through-bolt configurations\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive accepts standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and chemical-exposure environments\u003c\/li\u003e\n  \u003cli\u003eCap screw head style provides a clean bearing surface and flush appearance on the fastened assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use fastener for any application requiring a 3\/8-16 UNC hex socket cap screw with a 4-inch length under head in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/16-inch hex key or hex bit driver rated for the torque requirements of the assembly. Ensure the mating tapped hole or nut is clean and free of debris before threading to avoid cross-threading the coarse UNC thread. Apply appropriate thread lubricant or anti-seize compound when installing stainless fasteners into stainless tapped holes to prevent galling. Power down and de-energize any associated equipment before performing fastener service on live mechanical or electrical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: R40682446\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695300542770,"sku":"R40682446","price":954.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_82e9c80f-b266-4872-9a53-b07c0433c4f0.jpg?v=1788333675","url":"https:\/\/voomisupply.com\/products\/value-collection-r40682446-hex-socket-cap-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
