Frequently Asked Questions

What is a SEMS external tooth screw used for?

A SEMS external tooth screw combines a machine screw with a pre-assembled lock washer to resist loosening from vibration. It is used in industrial assembly, electrical panels, and equipment where a secure, shake-proof fastening is required across metal or plastic components.

What are the specifications of the SEMS screw #10-24 x 1/2 in?

This SEMS screw has a #10-24 thread size, 1/2 in length, steel construction with zinc-plated finish, and a hex drive size of 5/16 in. It includes an external tooth lock washer and comes in a 100-piece pack (MPN HTCEIF-1000500US-100P).

Where to buy SEMS external tooth screws worldwide?

How to select the correct SEMS screw size for an application?

Select a SEMS screw by matching thread size (#10-24), length (1/2 in), and drive size (5/16 in) to your assembly's hole and torque requirements. The external tooth washer provides locking action; ensure the screw material (steel, zinc-plated) is compatible with the mating surface to prevent galvanic corrosion.
