Vermont Gage 112302750 Class Zz Plus Plug Gage 2.75 Mm

Product Description

The VERMONT GAGE 112302750 is a Class ZZ Plus plug gage designed for precise bore and hole measurement in quality-control and inspection environments. Manufactured from tool steel with a 10 microfinish surface coating, this gage checks hole diameters at 2.75 mm with a tolerance of 0.00508 mm (0.005 mm). It is used in Go inspection applications to confirm that a hole or bore falls within the acceptable lower limit of a specified tolerance. Dimensional inspection professionals, machinists, and quality technicians use plug gages like this one as a fast, reliable go-no-go verification tool. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented inspection records and audit requirements.

This plug gage is suited for use in precision manufacturing, machine shops, and quality-assurance labs working with small-diameter bores. It is compatible with Go inspection workflows and can be used alongside set micrometers, verniers, and other calibrated measuring devices as noted by the manufacturer. The 2.75 mm diameter targets small-bore applications common in medical device, aerospace, and general precision machining. The compact overall length of 2.0 inches makes it practical for benchtop and in-process inspection use.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection settings. Store in a clean, dry environment and handle with lint-free gloves to prevent corrosion and dimensional change from skin oils. Clean the gage and the bore being checked before use to ensure accurate readings. Calibration intervals should follow your facility quality plan and applicable ASME B89.1 guidance.
