Heavy-duty vehicle component manufacturer Stemco has released the Zip-Torq single-piece axle fastener designed to streamline wheel end bearing adjustment.

With its single-piece, unitized design, the Zip-Torq eliminates special tooling and loose components like clips, keepers, snap rings or screws.

The Zip-Torq’s heavy-duty self-locking mechanism prevents inadvertent back-off to improve safety. Consistent locking force is maintained by the high-strength wave spring, preventing unwanted back-off.

“Zip-Torq is the natural result of our safety culture and decades of progress developing wheel end systems,” said Chip Stuhr, director of Stemco wheel end products. “The Stemco Pro-Torq nut revolutionized the way a wheel end was adjusted and set, and Zip-Torq is the next step in our mission of making the roadways safer.”
