Sized at 3\/8-16 UNC with a 2-inch length under head, this fastener is fully threaded and driven with a 5\/16-inch hex key. Constructed from alloy steel with a black oxide coating, it delivers solid tensile strength and basic corrosion resistance for indoor and light-duty industrial applications. Sold in a pack of 10, this fastener meets ASME B18.3 and ASTM A574 standards. It is commonly installed by machinists, millwrights, maintenance technicians, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for general mechanical assemblies, equipment mounting, jigs and fixtures, and maintenance and repair operations where a recessed hex drive is required. The 3\/8-16 UNC thread form is a standard coarse-thread pitch widely used across industrial equipment, pump housings, brackets, and machine frames. The black oxide finish provides a low-reflectance appearance and mild surface protection in dry or lightly oiled environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size 3\/8-16 UNC coarse thread for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head, fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for high-torque installation with standard Allen keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and low-glare finish\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 socket cap screw dimensional standards\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 ASME B18.3 and ASTM A574 compliant fasteners in that thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/16-inch hex key or Allen driver. Ensure mating threads are clean and free of debris before driving. Apply thread lubricant or anti-seize compound as required by the application to achieve accurate clamp load.
