The Vermont Gage steel no-go (-) plug gage is a class ZZ metric 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 are made of tool steel 60/62 Rc (cold stabilized), measure 2” long, are within .00001” round (per ASME B89.1.5), and have at least a 10-microinch finish for a smooth finish. Sizes are available from .20 mm to 25.49 mm (increments of .02 mm), with a tolerance of -.005 mm 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.

I wish I could say that I purchased this Vermont Gage for its intended purpose and it that it performed flawlessly. But, I didn’t and I can’t! However, I was working on a prototype project and I found myself in a position needing to know if a certain size steel shaft would be correct without having to buy, measure, and cut a length of that shaft just to see if if would work. Scanning Amazon for any metal object that I could use instead of using the method previously mentioned, I stumbled upon these Vermont Gages. I know a little about machining, but I wasn’t aware of these. Long story short, I was able to order a handful of these gages for a fraction of the cost of just one length of the steel shafts and was easily able to test each size and determine which size would best work for my project. As a bonus, I was also able to test the calibration of my dial indicators as well. Another unexpected purchase that worked out perfectly. The machined quality of these gages was just amazing and each one had a mirror finish with the size laser etched right into the gage.

Needed this to make sure my digital calipers were all reading right, turns out one was off by .04mm, which is alot in my line of work. Now I know, and that is great. Can't beat the price either.

Needed a small steel pin to replace a broken one for a hobby project and this worked great and was the exact specifications described which was very important to me as this had to fit within .001 of an inch to work for me.
