Vermont Gage 112112320 Class Zz Plus Plug Gage 12.32mm

Product Description

The VERMONT GAGE 112112320 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes and machined features at a nominal diameter of 12.32 mm. Manufactured from tool steel with a 10 microfinish surface coating, this gage delivers a tolerance of 0.00508 mm, making it suitable for Go inspection applications where tight dimensional control is required. Each unit ships with a Certificate of Accuracy traceable to NIST, providing documentation for quality-management and calibration programs. Licensed machinists, quality technicians, and metrology professionals use this gage in production and inspection environments.

This plug gage is used in manufacturing, machine shops, and quality-control labs for Go inspection of holes and bores at 12.32 mm nominal diameter. It is also compatible with setting and verifying micrometers, verniers, and other precision measuring devices. The compact overall length of 2.0000 inches makes it practical for bench inspection and in-process gauging on production floors. Its ASME B89.1 compliance makes it appropriate for use in regulated inspection environments requiring documented dimensional traceability.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection or production settings. Clean and inspect the gage and the part bore before use to remove chips, oil, or debris that could affect the measurement. Do not force the gage into a bore; excessive insertion force can damage the gage land or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional accuracy between uses.
