This English Diameter/Thread Gage Reticle is useful for checking the diameters of Drilled and Tapped holes. The diameter gages accurate to ±.00004”.
Pattern: Sixteen (16) sets of circles:
Drill and tap size measurements to include: 0-80 to 10-32 &-28, and 1/4-20 & -28 outer diameter of tap gauge indicates nominal thread O.D. The pattern is on the contact surface, right reading looking through so that the pattern can be in direct contact with the object being measured.
The Reticle Pattern is very durable, double layer, deposited evaporative Chrome/Chrome Oxide, for a reflectivity of less than 5% looking at the pattern. The Patterns on all Reticles manufactured by Max Levy are replicated from Precision Chrome on Glass Tooling under clean room conditions.
