The Vermont Gage steel no-go (-) plug gage is a class ZZ inch gage for calibrating measuring equipment and gage parts. A certificate of accuracy traceable to NIST is available for each gage, and each pin is marked with its size and direction of tolerance in sizes over .060”. Each gage is sealed in a volatile corrosion inhibitor (VCI) bag and packaged with a rust preventative.
All gages measure 2” long, are within .00001” round (per ASME B89.1.5), and have at least a 10-microinch finish for a smooth finish. This gage is made of tool steel 60/62 Rc (cold stabilized) for durability and is available with either a steel or black guard finish (to inhibit corrosion and for indicating wear). Sizes are available from .0040” to 1.0005” (increments of .001”), with a tolerance of -.0002” for longer wear.
Plug gages are precision ground cylindrical steel plugs used to measure the diameter and depth of drilled or machined holes. They are available in different classes, based on acceptable tolerance (allowed deviation from the stated size). Standard tolerances and classes for cylindrical gages up to .825” are as follows: Class XX (.00002" or .0005 mm), Class X (.00004" or .0010 mm), Class Y (.00007" or .0018 mm), Class Z (.0001" or .0025mm), and Class ZZ (.0002" or .0050 mm). For gages with a wider diameter, tolerance gradually increases for each class.
Since 1968, Vermont Precision Tools, Inc. (VPT) has been manufacturing a variety of precision round and ground pins, perforators, and special punches. Vermont Gage was formed in 1980, and manufactures a wide range of fixed limit gages. Located in Swanton, Vermont and Franklin, Kentucky, Vermont Gage manufactures 98% of the products they sell and is ISO 9001:2000 and ISO 17025 quality certified.

It's a simple product, but it is of great quality. It will make my job of checking hole tolerances a breeze. I have three of different sizes from them. I'd buy them again if needed.

Needed a replacement gage pin for the machine shop I work in. VT Gage is our go-to for pins because of their consistent excellent quality. The item received was exactly as described, so I couldn't be happier.

This is good and inexpensive gage for check calibration of your caliper. I ordered it with my digital calipers and just after uncover the gage from the bag I checked the caliper. It showed the same as indicated on the gage. I did measurement on few different places. Each time my caliper showed .309 in. So, this gage can be used before making measurement just to make sure, that your caliper is correct.
