    Phillips Hex Washer Machine Screw #3-81 x 1/2

    Part #: MSCHWF-381

    The MSCHWF-381 is a Type F hex washer head machine screw with a Phillips drive, typically made of zinc-plated steel for corrosion protection.

Its hex washer head provides a broader bearing surface for improved load distribution and vibration resistance, making it suitable for high-strength applications.
