Product Details
The B3/8-16 x 4-1/2" machine screw features a flat head design and is made of steel with a zinc CR+3 finish, packaged in a count of 100 pieces (BBI 586795). These machine screws are specifically engineered to fit through a pre-tapped hole or nut, creating a secure mating thread for the screw. The flat head configuration is ideal for applications where it is critical that the fastener does not protrude above the mating surface.
