Loose fasteners cause many industrial equipment failures. Locking machined washers—such as tab washers, spring lock washers, and wedge-lock washers—are custom-machined for reliability. Tab washers bend against bolt heads, locking them in place, while wedge-lock washers use cam-action to resist rotation even under vibration.
Designed to work with precision fasteners, they maintain preload and reduce bolt loosening in engines, rail systems, and machinery. Their precision-machined washers finish ensures surface engagement and long-term fastening security, making them superior to generic stacking methods.
