This fastener measures 3-1\/2 inches under the head and features partial threading along the shank. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance, it conforms to ASME B18.2.1 standards. The UNC thread form ensures broad compatibility with standard tapped holes and nuts. This screw is a dependable choice for structural and mechanical assemblies where strength and dimensional accuracy are required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for a wide range of trade applications including HVAC equipment mounting, electrical enclosure assembly, plumbing fixture installation, and general mechanical fabrication. The 3\/8-16 UNC thread is one of the most common coarse-thread sizes in North American trade work, making this fastener a practical stock item for service vans, job sites, and shop use. The partial threading allows for clamping without thread engagement through the full grip length, which is appropriate for bolted joints with a defined clamp zone.\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 hardware\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inches length under head — partially threaded shank\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for reliable tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion protection in dry and mildly humid environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eHex drive head accepts standard open-end, box, or socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex head cap screw for use with compatible 3\/8-16 nuts, threaded inserts, and tapped holes in steel, aluminum, and similar substrates common in mechanical and trade assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench, socket, or open-end wrench sized for a 3\/8-inch hex head cap screw.
