Stemco released its Zip-Torq axle fastener intended to streamline the wheel end bearing adjustment with its single-piece design, the commercial vehicle component supplier said. The product eliminates special tooling and loose components such as clips, keepers, snap rings or screws, the Longview, Texas-based company said. Plus, consistent locking force is maintained by the high-strength wave spring, further eliminating unwanted back-off. “Zip-Torq is the natural result of our safety culture and decades of progress developing wheel end systems,” Chip Stuhr, director of Stemco wheel end products, said in a statement. “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.” Stemco is a unit of EnPro Industries Inc.
