Buyer Questions
Frequently asked questions
What's the electrical bonding application of a tooth lock washer?
When tightened, the teeth scrape through paint or oxide layers on the mating surfaces, creating clean metal-to-metal contact. This is the standard way to make a reliable electrical ground connection through painted enclosures or grounding lugs.
