Vermont Gage 112217720 Class Zz Plug Pin Gage 17.72mm

Product Description

The VERMONT GAGE 112217720 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection at 17.72 mm diameter. Manufactured from steel, this pin gage carries a tolerance of 0.00508 mm, meeting the requirements of Class ZZ NoGo inspection work. Each unit ships with a Certificate of Accuracy that includes NIST traceability, making it suitable for use in calibrated inspection environments. The overall length is 2 inches. Licensed metrologists, quality technicians, and precision machinists use this type of gage to verify that a feature does not exceed its maximum material condition limit.

This pin gage is applied in NoGo inspection routines where confirming the upper boundary of a hole or bore diameter is required. It is also used as a reference standard when setting micrometers, verniers, and other measuring devices. Typical install scenarios include incoming inspection stations, machine shop quality control, and calibration labs. The NIST-traceable certificate supports documentation requirements for ISO 9001 and similar quality management systems.

Key Features

• Class ZZ Minus tolerance class for NoGo inspection applications
• 17.72 mm measurement diameter with 0.00508 mm tolerance
• Steel construction for dimensional stability and wear resistance
• Includes Certificate of Accuracy with NIST traceability
• 2-inch overall length for handheld single-hand operation

Compatibility

Designed for use in NoGo inspection applications and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a 17.72 mm diameter standard.

Installation Notes

Pin gages are handled and used by quality technicians and metrologists; no permanent installation is required. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Do not force the gage into a feature; a proper NoGo gage should not enter the hole if the feature is within tolerance. Store in the provided case or a protected environment to maintain calibration integrity.
