Vermont Gage 112302450 Class Zz Plus Plug Gage 2.45mm

Product Description

The VERMONT GAGE 112302450 is a Class ZZ Plus plug gage machined from tool steel, designed for precision bore and hole inspection in quality control and metrology applications. It measures 2.45 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for go inspection tasks where accurate internal dimension verification is required. The 10 microfinish surface treatment ensures consistent, repeatable gauge readings. Each unit ships with a Certificate of Accuracy carrying NIST traceability, meeting the documentation requirements of calibrated inspection tooling. Dimensional compliance conforms to ASME B89.1 standards. Machinists, quality technicians, and metrologists use this gage as part of go/no-go inspection routines or to set and verify micrometers, verniers, and other precision measuring devices.

This plug gage is suited for precision measurement environments including machine shops, tool rooms, quality assurance labs, and production floor inspection stations. It is appropriate for both incoming inspection and in-process verification of small-diameter bores and holes. The 2.45 mm diameter targets small-feature inspection common in precision machined parts, medical components, and fine mechanical assemblies. The included NIST-traceable certificate supports ISO 9001 and AS9100 quality management documentation requirements.

Compatibility

Designed for use as a go inspection gage and for setting micrometers, verniers, and other precision measuring devices requiring a 2.45 mm reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists — no permanent installation is required. Store the gage in its protective case when not in use to prevent surface damage and contamination. Clean the gage surface with a lint-free cloth before each use to avoid measurement error caused by debris or oil buildup. Handle with care to prevent drops, which can alter the gage geometry and invalidate calibration.
