Pinewood Car Derby Weights Tungsten 3.25oz. Pine Race Car Power with Varied Sizes of Incremental Cylinders. Heavy with No Lead. by Dr. Rocket

These worked perfectly in my sons pinewood derby car, they are very small and easy to install in the car. simply drill your hole, attach a little glue to the underside of the weight and push into the spots drilled in the underside of the car.

We used two sets of these weights building two cars this season. These are excellent! They worked perfectly to mass the right amount of weight to get to the 5 oz. allowed. They are easy to use by drilling hole in the bottom, sides, back, or top. We used wood glue to hold them in, and it worked great. We used a kitchen scale to verify. The sizes were perfect, we didn't have any trouble getting to 5 oz. exactly. The tungsten pieces were cool. They come pre-portioned like the description shows, we found the claimed weight to be accurate on a kitchen food scale. They are evenly shaped, and smooth; no irregularities in shape and size between two packages. We liked using the tungsten over lead for the obvious safety factors that come with small objects around young children and animals. We liked the cylinder shape for stylizing our cars, better than squares stacked on top. We also like the shape for the ease of drilling holes that will fit the weights, instead of trying to carve square shapes out of wood.Ultimately, we were very happy with these and would confidently recommend these for anyone looking for quality, accurate and easy weights for their pinewood derby creations.

These were easy to install since I just had to drill a hole the correct size, and depth. Much easier then adding a metal plate on the bottom. I'll be getting them again next year.

The weights were used to weight a model train engine. They worked fine. The cost was a bit (just a bit) high per ounce, relative to other tungsten weights but I needed the 3/8" diameter.

I think I used a 3/8” drill bit and these babies slid right in, snug fit. Great fit, would buy again.

We have been using these for years. Heavy, concentrated weight makes a fast car.

These fit perfectly into a hole made by a 3/8 Forstner drill bit. No glue was needed as they fit snugly.

I use these every Pinewood Derby for my son’s cars. Use a drill bit roughly the same size and you can squeeze them in without much effort under the car. My boys know they need to get as close to 5 oz as possible so it’s great that they have a selection to choose from. Throw them all in a scale and bam! Also, it doesn’t change the profile of the car. My two boys won first and second place for the pack this year using these
