Vermont Gage 111416550 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 111416550 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. It measures bores, holes, and internal features at a nominal diameter of 0.1655 inches with a tolerance of 0.0002 inches. Made from steel with a 10 microfinish surface coating, this gage is built for repeatable, reliable Go/NoGo inspection workflows. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Quality control technicians, machinists, and metrology professionals use this type of gage to verify that a hole does not exceed its maximum allowable size.

This plug pin gage is suited for NoGo inspection applications where a hole or bore must be confirmed within tight dimensional tolerances. It is also compatible with use alongside set micrometers, verniers, and other precision measuring devices as a calibration or reference standard. The 2-inch overall length provides adequate handling clearance for bench inspection or in-process checks on machined parts. Applications span manufacturing, machine shops, and quality assurance environments where steel gage blocks and pin gages are standard tooling.

Compatibility

Designed for use in NoGo inspection applications and as a reference standard with set micrometers, verniers, and other precision measuring devices.

Installation Notes

Pin gages are handled and used by quality control technicians and machinists in controlled inspection environments. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a feature; excessive insertion force can damage both the gage and the workpiece. Store in the provided case and allow the gage to reach ambient temperature before taking measurements to avoid thermal expansion error.
