Product Review
Tungsten Weight is the best weight for your pine derby cars because it allows you to pack more weight in a smaller area giving you more flexibility in your car design and more accurate weight placement for speed.
- Package contains five 3/8" diameter cylinders with chamfored edges for easy insertion. Three .5oz cylinders are .44" long, one .3oz cylinder is .27" long and one .2oz cylinder is .18" long.
- Just drill a standard 3/8" hole or holes in your car, insert the weights you need and cover the hole with wood putty so your weights are hidden in the car.
- Total weight of the 5 cylinders is 2 ounces.
 Note to metallurgists: These cylinders are Class 3 tungsten, 95% pure. It is an alloy of 95% pure tungsten, 5% nickel and iron.
- High Density, Less Space: Tungsten is 1.7x denser and smaller than lead. You can pack the most amount of weight in a small area, which means more inertia-producing speed at the finish line.
- Easily Tune for Max Speed: Multiple sizes makes it easy to precisely tune your car for racing BSA Pinewood Derby cars. Tungsten derby weights are essential for perfecting the center of gravity.
- Hide Weights or Show Them Off: Cover the tungsten weight holes with wood filler, sand down, and paint, keeping your speed secret safe. Alternatively, they can show in the back like real exhaust pipes.
- Easy to Install: These cylinder tungsten weights are 3/8” in diameter (standard drill bit size). With chamfered edges, these tiny weights will slide easily into your drill holes.
- Safe: The tungsten used in this set of eight tungsten weights is child-safe and non-toxic for easy handling. The cylinders also don’t contain any sharp edges, so you can use them confidently.
