Pro-Wheel Mandrel Screw







The Pro-Wheel Mandrel screw is a precision machined thumb screw for use with the Pro-Wheel Mandrel, or with a standard mandrel. The screw is equipped with a:

• knurled thumbscrew to simply mounting and dismounting wheels



• beveled face to ensure that wheel centers properly on the screw shaft.

The Pro-Wheel Mandrel screw fits most brands of pine derby wheels, however, some wheels are equipped with a wheel bore that is slightly smaller then the mandrel screw. The Pro-Hub tool can be used to ream out the wheel bore so that it fits on the screw.
