The integrated washer bites into the mating surface, making it ideal for industrial assemblies in machinery, electrical panels, and automotive applications where a secure, permanent joint is required.

This SEMS screw has M4x0.70 thread size, 20 mm length, stainless steel construction with passivated finish, pan head, and #2 drive size. It comes as a 5-pack (MPN 1-MPI-4-20). The integrated internal tooth lock washer provides vibration resistance without a separate washer.
