💡 How do internal and external tooth lock washers keep nuts from backing off?
These spring steel discs bite hard into both the nut and the mount to lock things down tight against shakeout and road chatter.
- Double-sided teeth grab the contact spots so you dodge annoying rattles and keep clamps holding firm when loads get bumpy.
- Oxide layers stop rust from creeping in while the exposed metal roots brush away grime to connect static electricity straight to the frame.
Machined tolerance ranges ensure smooth sliding fit on designated fasteners without requiring additional hardware modifications during installation.
