From Randy:
"TheLow-Profile Tungsten Round is thinner (only 9/32 inch) than the other rounds , so you can make your car thinner and still get the weighting benefit of a round."
How to Use this Product
A Tungsten Round can be easily used for pinewood derby car weighting if the weight of the car body, wheels, and axles is less than 1.75 ounces. Drill a 1-1/4 inch diameter hole into the bottom of the car body, and then epoxy the Round into the hole.
Since the Tungsten Round is very hard, do not plan to drill out any extra weight. Instead, use an alternate method to make fine adjustments such as adding/removing tungsten putty, beads, etc. In the photo, 3/16 inch tungsten cubes would be used.
(1) 3.2 ounce nominal weight - actual weight ranges from 3.19 to 3.23 ounces
