Speed Axles (4) – For BSA, MV, PineCar, and Outlaw Wheels

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! Francis B. - September 23, 2003 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.
