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 pre-assembled washer bites into the mating surface, making it ideal for electrical panels, machinery, and automotive assemblies where a secure, permanent fastening is required.

What are the specifications of the SEMS screw M2.5x0.45 12 mm?

This SEMS screw has an M2.5x0.45 thread size, 12 mm length, stainless steel construction with a passivated finish, pan head, and #1 drive size. It comes in a 10-pack. The manufacturer part number is 1-MPI-2.5-12.

How to select the correct SEMS screw for an application?

To select the correct SEMS screw, match thread size (M2.5x0.45), length (12 mm), and head type (pan) to your assembly requirements. Consider material compatibility—stainless steel with passivated finish offers corrosion resistance. The internal tooth lock washer provides vibration resistance without a separate washer.
