U.S.S. & S.A.E. Plastic Gauge

Push bolts through the holes to find the bolt diameter.  The length gauge measures “regular” heads from the left end and countersunk heads from the right end notched.  Nuts drop on the plugs along the top of the gauge.  S.A.E. fine thread nuts fit to the base of the plugs, U.S.S. coarse thread nuts fit half-way.
