How Wedge Lock Washers Resist Vibration Better Than Regular Washers

 

In environments where vibration is a constant threat, like industrial machinery or off-road vehicles, wedge lock washers outperform standard washers by locking bolts mechanically, not just by friction. These washers come in pre-assembled pairs with internal cams that engage when the bolt begins to turn, producing tension that resists loosening. The more the bolt tries to rotate, the tighter the lock—making them ideal for mission-critical assemblies.

If you’ve experienced bolt loosening due to movement, temperature shifts, or load changes, upgrading to vibration-resistant wedge lock washers is an easy win. They're particularly useful in turbine assemblies, rail systems, mining rigs, and automotive components like suspension systems. When downtime costs money—or even lives—this simple switch can protect your investment and keep your equipment secure.
