The STEMCO Zip-Torq single-piece axle fastener simplifies and streamlines the wheel end bearing adjustment with its single-piece, unitized design. The fastener features a unitized design using no screws, clips or lock rings, for faster installation, the Zip-Torq eliminates special tooling and easy-to-lose components like clips, keepers, snap rings or screws. The patented Zip-Torq heavy duty self-locking mechanism also delivers increased simplicity and safety by preventing inadvertent back-off. Consistent locking force is maintained by the high-strength wave spring, further eliminating unwanted back-off. When the locking feature is disengaged by a breaker bar, Zip-Torq can be easily removed.
