Description:
Designed to securely hold 5/16” to 9/16” axles for easy wheel hub and pedal adjustments, the Park Tool AV-4 is a must for every mechanic's workbench. Just insert axle into one of the three precision-machined openings and tighten in a bench vise. The Park Tool AV-4's bridge spring keeps the jaws aligned and allows the tool to automatically open when the bench vise is opened. Aluminum jaws won't damage axle threads.
