Sized at 3\/8-16 UNC with a 4.25-inch length under the head, this screw is partially threaded, which allows it to clamp materials securely without fully threading through the clamped section. Made from alloy steel with a black oxide finish, it meets ASME\/ANSI B18.3 and ASTM A574 standards. A 5\/16-inch hex drive is required for installation. Machinists, maintenance mechanics, and industrial assembly technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis cap screw fits general industrial and mechanical assembly applications where a recessed hex drive is preferred over an external hex head. The partially threaded design suits bolted joint assemblies where thread engagement length and clamping distance are carefully specified. Typical use cases include machine frames, jigs, fixtures, and equipment housings in both light and heavy manufacturing environments. The 3\/8-16 UNC thread is one of the most common coarse-thread fastener sizes in North American industrial equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements for socket cap screws\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection on finished assemblies\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for precise clamping in bolted joint applications\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex drive accepts standard hex keys and socket bits\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and aftermarket replacement fastener for any tapped 3\/8-16 UNC threaded hole requiring an ASME\/ANSI B18.3 socket cap screw with a 4.25-inch length under the head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 5\/16-inch hex key or socket drive.
