Park Tool Heavy-Duty Axle and Pedal Vise

Designed to securely hold 5/16- to 9/16-inch axles for easy hub and pedal adjustments Park Tool's AV-4 Heavy Duty Axle and Pedal Vise is a must for every mechanic's work bench. Just insert an axle into one of the three precision-machined openings and tighten in a bench vise. The AV-4's bridge spring keeps the jaws aligned and allows the tool to automatically open when the bench vise is opened. Plus, its aluminum jaws won't damage axle threads.
