CLASS ZZ REPLACEMENT PIN GAGES & ASSEMBLIES

CLASS ZZ ASSEMBLIES A great Go/No Go inspection Tool!

CLASS ZZ REPLACEMENT PINS Keep old sets in compliance!

Green end Go

Purchase your Class ZZ gages factory assembled in a handle for production gaging. Class ZZ assemblies are economical and very versatile for Go/No Go gaging. If the Go (Green End) fits and the No Go (Red End) doesn’t, your part passes inspection. It doesn’t get any easier! Each assembly includes 1 line (up to 15 characters) of custom marking.

Replace missing, damaged, or worn-out Class ZZ gages from your existing sets & Libraries. These replacement pins are perfect in updating your old sets, and bringing them back into compliance. Each pin is individually marked with size and direction of tolerance. Packaged with a rust preventative, these pins maintain an indefinite shelf life; so keep several of your most used sizes on hand! Each pin is NIST traceable and includes a Certificate of Accuracy printed on back of package.
