Value Collection MP72168 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The Value Collection MP72168 is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies and structural applications. It features a 3/8-16 UNC thread size with a 2-1/4 inch length under head and is partially threaded for controlled engagement. The 5/16 inch hex drive accepts a standard hex key or Allen driver. Made from alloy steel with a black oxide finish, this screw delivers solid tensile strength while the coating provides moderate corrosion resistance. Each package contains 10 screws. Typical installers include HVAC technicians, plumbers, electricians, and general mechanical contractors working with equipment mounting and structural hardware.

This screw is suited for use in equipment panels, motor mounts, compressor brackets, pump housings, and similar mechanical assemblies found in residential and light commercial trade work. The partial threading supports clamping force in through-hole applications where the unthreaded shank spans a clearance hole. It conforms to ASME B18.3 and ASTM A574 standards, making it appropriate for load-bearing fastener applications where a recognized fastener standard is required by spec or code.

Installation Notes

Installation is performed using a 5/16 inch hex key or Allen driver. Always power down or de-energize equipment before disassembling or reassembling fastened assemblies. Ensure the mating tapped hole is clean and free of debris before driving the screw. Do not exceed the torque range appropriate for 3/8-16 alloy steel socket cap screws as specified by the equipment manufacturer or applicable mechanical codes.
