Pinewood Derby axle file to remove burrs and reduce friction.

BSA axles are actually nails that have burrs and crimp marks from manufacturing. These defects act like brakes and must be removed or your car will have trouble reaching the finish line!

This handy little file solves the problem for you. Just put the axle in a vice and file off the defects.

We recommend getting the axle polishing kit to complete the job of turning your rough-cut nails into high performance axles!
