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 industrial assemblies in machinery, electrical panels, and control systems where reliable fastening is critical.
What are the specifications of the SEMS screw #8-32 x 1/4 in?
This SEMS screw has a #8-32 thread size, 1/4 in length, stainless steel passivated construction, pan head, and #2 drive size. It comes in a 50-piece pack (MPN 1-PPI-8C-25). The integrated internal tooth lock washer provides vibration resistance without a separate washer.
