Description
Say "Goodbye" to burrs and crimp marks! Pinewood Derby Speed Axles are equipped with a straight, round, and smooth shaft, and a slightly tapered head. But most importantly, there are NO BURRS OR CRIMP MARKS, so you can prepare these precision axles with minimal effort!
Benefits
- Burrs and crimp marks are not present, eliminating tedious work
- Axle head is slightly beveled to minimize contact with the outside wheel hub
- Axle shaft is formed to a high tolerance, ensuring top performance
- The superior zinc plating provides a nice surface for polishing
I purchased and tested Speed Axles from several different vendors. Your Speed Axles were faster by at least 100th (0.01) of a second than the others!

Usage
The axles substitute for official BSA, PineCar, and other nail type axles. Just a light polishing with our Axle Polish is all that is required to prepare the axles for racing. If you use our Axle Polishing Kit, skip the three coarsest papers - use the two finest papers.
Note that these axles closely resemble BSA and PineCar axles, but are not exact replicas (see photo below). So, if your race has a strict axle requirement, consider using our Official BSA Speed Axles, or use our specialty tools and supplies to prepare a set of the official nail axles.
