Steel class zz gage pins sets. There are several basic types of products. I took a quick look at availability and there are plus sets and minus sets. Uses for precision go nogo measuring of hole sizes and depths checking hole location and distance and setting micrometers.

At msc you will find the plug pin gage sets you need for measuring hole sizes and depths and checking locations and distances between holes. Which would you buy minus or. All gages are uniformly 2 long with ground ends allowing you to use both ends for increased gage life. I need to do some interference fits 1 4 for example.

Go gages and no go gages are fixed limit gages with gauging limits based on the plus or minus tolerances of inspected parts. Use for go nogo inspection. Go gage dimensions are based on. Enco has free shipping promotions regularly.
