It features a 3\/8-16 UNC thread size, a 6-inch length under head, and a 5\/16-inch hex drive. Constructed from alloy steel with a black oxide finish coating, this fastener delivers strong clamping force and moderate corrosion resistance. It is installed using a hex key or Allen wrench and is appropriate for machine assembly, structural clamping, and equipment repair tasks performed by maintenance technicians and tradespeople.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general industrial fastening applications where a socket-drive cap screw with partial threading is required. The partial thread profile allows for greater thread engagement in thicker materials and provides a clamping zone along the unthreaded shank. It is commonly used in machine frames, brackets, fixtures, and fabricated assemblies across manufacturing and maintenance environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread size for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e6-inch length under head accommodates deep clamping and thick-stack assemblies\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a smooth clamping surface between fastened components\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex drive for precise torque application with a standard Allen key\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction offers high tensile strength for demanding fastening applications\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock fastener for applications requiring a 3\/8-16 UNC partially threaded hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a 5\/16-inch hex key or Allen wrench. De-energize and lock out any equipment before fastener service to comply with applicable safety protocols. Ensure the receiving tapped hole is clean and free of debris before installation.
