Frequently Asked Questions

What is a SEMS screw with external tooth lock washer used for?

A SEMS screw with an external tooth lock washer is used to fasten components while resisting loosening from vibration.

What are the specifications of the SEMS Screw M2.5x0.45?

This SEMS screw has an M2.5x0.45 thread size, 5 mm length, stainless steel construction with passivated finish, pan head, and #1 drive size. It comes in a 25-piece pack (MPN 1-MPE-2.5-5). The external tooth lock washer is pre-assembled to prevent loosening under vibration.
