Alcoa to Supply Huck® U-Spin™ Fasteners for Volvo Air Ride Suspensions

Waco, Texas -- Alcoa Fastenings Systems has announced that Huck® brand U-Spin™ fasteners -- installed via a computer-controlled swaging process that produces a vibration-proof, maintenance-free clamp group – are the standard fasteners for the proprietary Volvo air suspensions installed on Volvo Trucks North America, Inc.’s tandem-axle Class 8 trucks. The U-Spin fasteners became standard for Volvo in the first quarter of 2005.

Volvo is the first and only manufacturer to offer these “locking U-bolts” to truck customers. Derived from Huck-Spin® fasteners, which have become synonymous with premium frame construction for Class 8 vehicles, U-Spin fasteners feature swaged-on collars that can’t work loose. The swaging process forces the collar material into the bolt threads to form a permanent clamp that never needs re-tightening, even in severe service. For a large fleet, the U-Spin’s elimination of periodic U-bolt maintenance can provide significant savings in vehicle downtime and labor costs.
 
From a truck (or trailer) manufacturer’s perspective, U-Spin fasteners offer improved performance  and customer satisfaction. Precise, computer-controlled installation -- of two U-Spins at a time, if desired -- can speed up assembly while simultaneously ensuring accuracy and consistency impossible to obtain with a torque wrench. The computerized installation tool even provides pre-set spread locations to accommodate a variety of bolting patterns.
