💡 What makes external tooth lock washers handy for high vibration applications compared to standard flat hardware?

- Folks keep these on the shelf because 18 8 steel never flakes out or turns orange in damp garages.
- Techs cut downtime since the toothed ring snaps tight right away without messing with messy gel adhesives.
- Grabbing a full case saves trips to the hardware run since every unit matches the 1 4 spec for instant swaps.
