Axle Fasteners

Auto-Torq^®

STEMCO is changing the game for wheel ends again! The Auto-Torq axle fastener is designed to streamline wheel end installation by eliminating the need for complex processes and specialty tools—no washers, clips, snap rings, screws, or keepers needed. An all-in-one solution that’s compatible with any industry hub manufacturer, Auto-Torq securely applies the optimum clamp load on the bearings every time to minimize wear and maximize service life. Simply put, installation has never been easier.

Since most axle fastener replacements involve a seal replacement as well, we offer Auto-Torq as a matched pair with any of our premium wheel seals – simplifying purchasing decisions and maximizing the performance and longevity of your wheel ends. Find which seal is best suited to your needs through the links below or contact your STEMCO sales representative for more insight on these powerful pairs.

Auto-Torq is also available as an individual component, allowing our customers to bring the pinnacle of axle fastener technology to any wheel end in their fleet.
