Frequently Asked Questions

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

A SEMS screw with an internal 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 general industrial fastening applications where a secure, permanent hold is required.

What are the specifications of the SEMS screw M3x0.50 4 mm?

This SEMS screw has an M3x0.50 thread size, 4 mm length, stainless steel construction with a passivated finish, pan head, and #1 drive size. It comes in a 25-piece pack. The integrated internal tooth lock washer provides vibration resistance. The manufacturer part number is 1-MPI-3-4.

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

To install a SEMS screw with an internal tooth lock washer, drive it into a tapped hole or nut using a #1 drive tool. The integrated washer will compress and its teeth will bite into the surface, preventing loosening. Avoid over-torquing, as this can damage the teeth or strip the threads. Use standard torque values for M3 stainless steel fasteners.
