Ball-Lock Washers
This unique solution dramatically improves assembly time by allowing the operator to quickly maneuver a single tool around the flange while eliminating the safety hazards associated with backup wrenches. The Ball Lock washer employs the use of hardened steel ball bearings that embed and grip into the flange face and nut bearing surfaces. This mechanical lock begins to occur during the hand tightening stage and is maintained throughout the tightening process. The result is a technology that eliminates the need for a back-up wrench and the need for an operator to place his hands and fingers at risk in a pinch point zone.

Nord-Lock Washers
Nord-Lock washers secure bolted joints with tension instead of friction. The system consists of a pair of washers with cams on one side and radial teeth on the opposite side. Since the cam angle ‘α’ is greater than the thread pitch ‘β’ a wedge effect is created by the cams, preventing the bolt from rotating loose.

Belleville Spring Flange Washers
Belleville washers were designed for flange connections to help control bolt stress and ensure proper gasket pressure is maintained. Belleville washers are available in several materials, sizes and designs determined by the environment of the application.
