This screw features a 3\/8-16 UNC thread size with a 2-1\/2-inch length under head and is partially threaded for positive thread engagement in tapped holes. The 5\/16-inch hex drive accepts a standard Allen key or hex bit. Constructed from alloy steel with a black oxide finish, it provides solid corrosion resistance for indoor and moderate-environment applications. Electricians, HVAC techs, plumbers, and millwrights commonly use socket cap screws when clearance or torque requirements favor a recessed drive over a hex head.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in equipment panels, mechanical assemblies, pump housings, motor mounts, and structural brackets where a flush or low-profile head is required. The partial threading allows the unthreaded shank to act as a shoulder against the mating part, which is particularly useful in assemblies requiring precise alignment or shear load transfer. The 3\/8-16 UNC coarse thread pattern offers reliable engagement in steel, cast iron, and aluminum tapped holes commonly found in HVAC equipment and plumbing infrastructure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard tapped holes in steel and aluminum\u003c\/li\u003e\n  \u003cli\u003e2-1\/2-inch length under head provides fastening depth for thicker assemblies and structural connections\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank aids alignment and handles shear loads in precision assemblies\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive accepts standard Allen keys and hex bits for high-torque installation in tight spaces\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction offers high tensile strength compared to standard carbon steel fasteners\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces surface glare in finished assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex socket cap screw for use in any application requiring this thread size, drive type, and length under head.

Ensure the tapped hole is clean and free of debris before installation. De-energize or shut down any equipment before fastening or removing hardware on live mechanical or electrical assemblies. Follow applicable mechanical and equipment manufacturer guidelines for fastener torque and thread engagement depth.\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: 2-1\/2 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\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.087 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 13\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: 88546866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714865398066,"sku":"88546866","price":32.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ae15fc897b6750dfcc7910cf66f2778.jpg?v=1788507159","url":"https:\/\/voomisupply.com\/products\/value-collection-88546866-hex-socket-cap-screw-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
