All the the Reference Charts and Conversion Tables that you use most in this handy, compact collection. Charts include Gagemaker’s Tolerance, Geometric Tolerancing, Form Parameters, Surface, Hardness, Thread Series and many more.

The handy 5.5” x 8.5” booklet is bound only by a metal ring so that individual charts can be removed, and the whole Reference Guide can be hung on a machine or bulletin board for quick and easy access. Every page is heavy, UV coated paper to stand up to dirt and frequent usage. Quantity discounts are available.
