Vermont Gage 112208480 Class Zz Plug Pin Gage 8.48mm

Product Description

The VERMONT GAGE 112208480 is a Class ZZ Minus plug pin gage machined from steel for dimensional inspection work. It measures 8.48 mm in diameter and is used to verify that a hole or bore does not exceed the maximum allowable size, making it a NoGo inspection tool. The gage holds a tolerance of 0.00508 mm, providing precise go/no-go verification in quality control environments. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy that includes NIST traceability, meeting the documentation requirements of most quality management systems. Machinists, metrology technicians, and quality inspectors are the primary users of this tool.

This plug pin gage is suited for use in manufacturing, machine shops, and inspection labs where bore diameter acceptance testing is required. It is designed for NoGo inspection applications and is also compatible with setup and verification tasks involving set micrometers, verniers, and other precision measuring devices. The 10 microfinish surface coating on the gage pin supports repeatable, accurate measurements across multiple uses without introducing dimensional error from surface irregularities.

Installation Notes

Plug pin gages are handled and used by metrology technicians and quality control inspectors. Store the gage in its protective case when not in use to prevent surface damage or corrosion that could affect measurement accuracy. Clean the gage pin and the bore being inspected before use to remove debris or oil that could cause false readings. Follow your facility's calibration schedule and handle the pin by the handle or shank, not the measuring surface, to avoid introducing dimensional error from thermal expansion or surface wear.
