It measures 1-3\/4 inches under the head and uses a Unified National Coarse (UNC) thread standard. The zinc coating provides basic corrosion resistance for general-purpose fastening applications. This screw is driven with a 9\/16-inch hex key or wrench. It is a standard inch-measurement fastener suited for assembly, maintenance, and repair work across mechanical, structural, and equipment installations performed by electricians, HVAC technicians, plumbers, and general tradespeople.\u003c\/p\u003e\n\u003cp\u003eThis fastener fits general-purpose bolted connections where a 3\/8-16 UNC coarse-thread screw with partial threading is required. Partial threading allows the unthreaded shank to bear shear loads, making it appropriate for applications where the fastener passes through clearance holes before engaging a threaded hole or nut. Typical use cases include equipment mounting, panel assembly, bracket attachment, and light structural connections in both residential and commercial trade settings.\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 nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows the unthreaded section to carry shear loads\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets standard requirements for general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance in dry to mildly humid environments\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head suits medium-depth clamping applications\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch hex drive compatible with standard wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose inch-series hex head cap screw compatible with any standard 3\/8-16 UNC threaded hole or hex nut in equipment, fixtures, or structural assemblies requiring a partially threaded fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson using a properly sized 9\/16-inch wrench or socket. Ensure mating threads are clean and free of debris before installation.
