Vermont Gage 112403650 Class Zz Minus Plug Pin Gage 3.65 Mm

Product Description

The VERMONT GAGE 112403650 is a Class ZZ minus plug pin gage designed for precise hole diameter inspection in machining and quality control applications. It measures 3.65 mm in diameter with a tolerance of 0.00508 mm, making it suited for NoGo inspection work where tight dimensional verification is required. The gage is manufactured from steel with a 10 microfinish surface coating. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting documentation requirements in calibrated inspection environments. Machinists, quality technicians, and metrology professionals use this type of gage as part of go/nogo inspection routines.

This plug pin gage is intended for NoGo inspection applications and is compatible with use alongside set micrometers, verniers, and other measuring devices. It is a single-pin gage suited for bench-level inspection in machine shops, manufacturing facilities, and quality labs working with small-diameter hole tolerances in the metric range. The NIST-traceable accuracy certificate makes it appropriate for environments requiring documented traceability in their measurement tooling.

Compatibility

Designed for use in NoGo inspection applications and compatible with set micrometers, verniers, and other standard measuring devices requiring a 3.65 mm reference diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists at inspection stations. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the pin into a bore; improper insertion can damage both the gage and the workpiece. Store with the Certificate of Accuracy to maintain traceability documentation.
