Frequently Asked Questions
What is a SEMS external tooth screw used for?
A SEMS screw with an external tooth lock washer is used to fasten components while resisting loosening from vibration. The integrated washer bites into the mating surface, making it ideal for electrical grounding, panel assembly, and machinery applications where a secure, permanent hold is required.
What are the specifications of the SEMS screw M2.5x0.45 8 mm?
This SEMS screw has an M2.5x0.45 thread size, 8 mm length, stainless steel construction with passivated finish, pan head, and #1 drive size. It comes in a 25-piece pack (MPN 1-MPE-2.5-8). The integrated external tooth lock washer prevents loosening under vibration.

How to install a SEMS screw with external tooth lock washer?

Avoid over-torquing to prevent stripping the stainless steel threads or damaging the washer teeth.
