Serrated Flange Lock Nuts
Serrated flange lock nuts have a wide flange with serrated teeth underneath. The flange works as a built-in washer to spread the load, and the teeth bite into the surface to keep the nut from loosening under vibration. One part replaces a nut, flat washer and lock washer, so assembly is faster.

FAQ
Can I use a washer with a serrated flange nut?
No. The serrations need to bite into the work surface. A washer underneath stops them from locking.
Will serrated nuts damage the surface?
They leave marks, which is how they lock. On painted or soft surfaces you want to protect, use a nylon insert lock nut instead.
