Screw Checker for Metric Sizes

Here is the Metric version of that unique tool every modeler should have these days. When you can't figure out what size or thread the screw is or if it is Metric, just size it with the hole on the left (for the correct diameter) then thread it into the proper thread hole to the right and you have your screw identified. This checker is for Metric sizes from 2mm to 7mm and tells you drill sizes also. THESE PLATES ARE MADE OF CHROME PLATE STEEL. "NOT THOSE PLASTIC type that strip after using them" - MADE IN USA!
