Vermont Gage 112312190 Class Zz Plus Plug Gage 12.19mm

Product Description

The VERMONT GAGE 112312190 is a Class ZZ Plus plug gage with a 12.19 mm diameter, manufactured from tool steel with a 10 microfinish surface coating. It is used to verify bore and hole dimensions to ASME B89.1 standards with a tolerance of 0.00508 mm. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for controlled inspection environments. Machinists, quality technicians, and metrology professionals use this gage to perform go-type inspection checks on machined parts and assemblies. The overall length is 2.0000 inches.

This plug gage is designed for go inspection applications, including use with micrometers, verniers, and other precision measuring devices. It fits into standard metrology workflows on the shop floor or in a quality lab where dimensional verification of 12.19 mm features is required. The Class ZZ Plus tolerance class makes it appropriate for production-level inspection where repeatable, traceable measurement is required.

Compatibility

Designed for use in go inspection applications and compatible with standard plug gage handles and holders. Also suited for use alongside micrometers, verniers, and other calibrated measuring devices in production or quality control settings.

Installation Notes

Plug gages should be handled by quality technicians or metrology personnel following established calibration and inspection procedures. Store the gage in its protective case when not in use to prevent surface damage that could affect measurement accuracy. Do not force the gage into a bore; apply only light hand pressure to avoid wear on the precision ground surface. Clean the gage and bore surfaces before each use to ensure accurate readings.
