Vermont Gage 112206740 Class Zz Minus Plug Pin Gage 6.74 Mm

Product Description

The VERMONT GAGE 112206740 is a Class ZZ Minus plug pin gage designed for precise hole diameter inspection in metrology and quality-control applications. The gage measures 6.74 mm in diameter with a tolerance of 0.00508 mm, making it suited for NoGo inspection work where tight dimensional verification is required. The steel construction provides durability under repeated use in shop or lab environments. Overall length is 2 inches, keeping the tool compact for use in close-tolerance measurement setups. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming calibration to a recognized national standard. Machinists, quality technicians, and metrology professionals are the primary users of this gage.

This plug pin gage is used wherever precise bore or hole verification is needed, particularly in NoGo inspection applications. It is also compatible with setup and calibration tasks involving set micrometers, verniers, and other measuring devices. Typical environments include machine shops, manufacturing floors, and inspection labs handling parts that require dimensional confirmation to tight tolerances. The Class ZZ designation indicates a defined tolerance grade appropriate for general inspection-grade gauging at this diameter range. The 10 microfinish surface coating supports accurate, repeatable contact measurements.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists familiar with precision measurement procedures. Store the gage in a protective case away from contaminants and temperature extremes to preserve calibration integrity. Clean the gage surface before each use and avoid dropping or striking the gage, as impact can alter dimensional accuracy. Recalibrate or replace the gage if wear or damage is suspected, and reference applicable quality-system standards for inspection interval requirements.
