Vermont Gage 112104960 Class Zz Plus Plug Gage 4.96 Mm

Product Description

The VERMONT GAGE 112104960 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore and hole diameters to tight dimensional tolerances. With a nominal diameter of 4.96 mm and a tolerance of 0.00508 mm, this gage delivers reliable pass/fail inspection results in production and quality-control environments. The 10 microfinish surface reduces wear on the gage and the workpiece during repeated insertions. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements for calibrated tooling programs. Licensed metrology technicians and quality inspectors are the primary users.

This plug gage is suited for go inspection of precision bores in manufacturing, machining, and assembly operations. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a known reference diameter. The 2.0 inch overall length fits standard plug gage handles for easy bench or floor use. Typical applications include incoming inspection, in-process quality checks, and calibration verification across light manufacturing and precision machining environments.

Compatibility

Designed for use with standard plug gage handles and suitable for setting micrometers, verniers, and other measuring devices requiring a calibrated 4.96 mm reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and metrology personnel following standard inspection procedures. Clean and inspect the gage and workpiece bore before each use to prevent damage to the gage surface. Store the gage in its protective case when not in use to preserve the microfinish and dimensional integrity. Calibration intervals should follow the facility quality management plan and applicable ASME B89.1 guidelines.
