The tension generated by the deflection of the Regular helical spring split lock washer meets the needs of most commercial applications. It is, therefore, the most popular type spring lock washer in terms of usage and production. Our lockwashers are made in the USA. They meet all ASME standards in addition to RoHS and DFARS compliance when required.

We also have Mil-Spec Helical Spring Split Lockwashers.
