💡 Why do tradesmen use slotted lock washers on steel assemblies?
These handy stainless spring washers save your threads by resisting vibration better than plain flat washers alone.
- The interlocking teeth grab the nut and bolt head to kill rotation and prevent fasteners from falling out over time.
- Spring tension keeps constant preload on the joint which helps stop leaks and wobbles on moving equipment.
- Corrosion resistant coatings protect your expensive gear from rotting when exposed to weather or shop chemicals.
