Vermont Gage 112319230 Class Zz Plus Plug Gage 19.23mm

Product Description

The VERMONT GAGE 112319230 is a Class ZZ Plus plug gage designed for precision bore inspection in metrology and quality control environments. With a 19.23 mm diameter and a tolerance of 0.00508 mm, this gage delivers the accuracy required for Go inspection applications. Constructed from tool steel with a 10 micro finish coating, it is built to withstand repeated use in production and inspection settings. Each unit ships with a Certificate of Accuracy that includes NIST traceability, making it suitable for documented quality systems. Machinists, quality technicians, and metrologists are the primary users of this instrument.

This plug gage is used in machine shops, manufacturing facilities, and calibration labs where tight bore tolerances must be verified. It is well suited for use alongside micrometers, verniers, and other precision measuring devices as a reference standard or a go/no-go inspection tool. The 2.0000-inch overall length provides adequate reach and handling clearance for most bore inspection tasks. It is applicable wherever ASME B89.1 dimensional standards govern the inspection process.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists; no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage or corrosion that could affect dimensional accuracy. Clean the gage and the bore being checked before use to remove debris that could produce false readings. Allow the gage to reach ambient room temperature before measurement if it has been stored in a significantly different environment.
