How to install a SEMS screw with internal tooth lock washer?
Install a SEMS screw by driving it into a pre-tapped hole or nut using a #2 drive tool. The integrated lock washer faces the mating surface; as you tighten, the internal teeth bite into the material to prevent loosening. Avoid over-torquing, which can strip the threads or damage the washer.
