Manufactured from alloy steel with a black oxide finish, this fastener meets ASME\/ANSI B18.3 and ASTM A574 standards. It features a 5-40 UNC thread size, a 3\/16-inch length under head, and is driven by a 3\/32-inch hex key. The black oxide coating provides mild corrosion resistance and reduces light reflection. This screw is fully threaded along its length, ensuring consistent clamping force across the entire engaged thread depth.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for light-duty mechanical assemblies where space-constrained or recessed socket drive access is required. Common applications include instrument panels, small machine components, jigs, fixtures, and electronics enclosures. The 5-40 UNC thread designation makes it a standard choice in precision equipment where fine thread engagement and controlled torque are priorities. Technicians and machinists working in industrial maintenance, tool-and-die, and equipment fabrication environments commonly specify this size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread size for precision fastening in light-duty assemblies\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch length under head, fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e3\/32-inch hex socket drive for use with standard Allen or hex key tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimensioned hex socket cap screw per ASME\/ANSI B18.3, suitable for use in any application requiring a 5-40 UNC fully threaded socket head cap screw with a 3\/16-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 3\/32-inch hex key or Allen driver. Ensure the mating threaded hole is clean and free of debris before installation. Do not exceed the torque capacity appropriate for a 5-40 alloy steel fastener in the base material being used.
