ALL METAL LOCKNUT M/F 20MM X 1.5

Quantity:

A lock nut is a specialized nut designed to resist loosening under vibration or torque. It typically incorporates a friction-based or mechanical locking feature, such as a nylon insert (in a nyloc nut), a deformed thread, or serrated flanges. Lock nuts maintain tightness and integrity even in dynamic or high-vibration environments without requiring additional locking components.
