Vermont Gage 112216520 Class Zz Minus Plug Pin Gage 16.52 Mm

Product Description

The VERMONT GAGE 112216520 is a Class ZZ minus plug pin gage machined from steel and designed for NoGo inspection applications. It measures 16.52 mm in diameter with a tolerance of 0.00508 mm, making it suitable for precise bore and hole verification in production and quality-control environments. The gage ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in ISO and other quality management systems. At 2 inches in overall length, it fits standard pin gage handles and accessories. Metrology technicians, machinists, and quality inspectors rely on this type of gage to confirm that a bore has not exceeded its maximum allowable size.

This pin gage is used in NoGo inspection routines where the gage must not enter a correctly sized bore. It is also suited for setting and verifying micrometers, verniers, and other measuring devices that require a known reference diameter. Typical applications include incoming inspection, in-process quality checks, and calibration support in machine shops, manufacturing facilities, and metrology labs. The minus designation indicates the gage is ground to the lower boundary of the Class ZZ tolerance band.

Key Features

• Class ZZ minus tolerance ground to 0.00508 mm for NoGo inspection use
• 16.52 mm measurement diameter in steel construction
• 2 inch overall length compatible with standard pin gage handles
• 10 micro-inch coating/finish for surface consistency and wear resistance
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use with standard pin gage handles and compatible with micrometers, verniers, and other measuring devices requiring a 16.52 mm reference diameter for setting or NoGo inspection.

Installation Notes

Pin gages are handled by metrology technicians and quality inspectors. Clean the gage and the bore or measuring device contact surfaces before use to prevent contamination from affecting readings. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Do not force the gage into a bore; a correctly applied NoGo gage should not enter a conforming hole under hand pressure alone.
