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 pre-assembled washer bites into the mating surface, making it ideal for industrial assemblies in machinery, electrical panels, and automotive applications where a secure, permanent joint is required.
What are the specifications of the SEMS #10-32 screw?
This SEMS screw has a #10-32 thread size, 3/8 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 HTCEFIF-1000370US-100P). The zinc plating provides corrosion resistance for general industrial use.

How to install a SEMS screw with external tooth lock washer?
Install a SEMS screw by driving it with a 5/16 in hex socket or driver until the external tooth washer contacts the mating surface. Tighten to the recommended torque for #10-32 steel fasteners—typically 20-30 in-lb—to allow the washer teeth to embed and prevent loosening. Avoid over-torquing to prevent thread stripping.
