Have you been looking for a test weight to verify that your Pinewood Derby or Awana car is the correct weight? These were custom produced for SCALES USA. By ordering a huge quantity directly from the manufacturer, We were able to get a big price reduction from the original dealer cost . We also include a manufacturers certificate with each weight (Not a NIST Certificate). These are good looking weights, nice smooth finish and shiny nickle chrome plating. They are stamped 5 OZ on the top. The weight has a adjustment cavity in the bottom, and has been adjusted to the tolerance described. The cavity is sealed with a tamper proof seal. These are great to check your scale so that the weight of your Pinewood car is "right on".
