More About Part Number 405163

These 4-40 x 3/8" Machine Screws feature a Round Head with a Phillips Drive and are made from Steel. Machine screws are uniform-diameter threaded fasteners commonly used with tapped holes or nuts in machinery, electronics, and general assembly applications. They feature a Black Oxide Finish, which provides mild corrosion resistance and a dark matte appearance and is commonly used in indoor or lightly protected applications. The Round Head features a fully domed profile that provides a clean finished appearance and distributes load across the surface of the material. A Phillips drive features a cross-shaped recess designed for efficient installation with standard Phillips drivers and power tools.
