Vermont Gage 112221260 Class Zz Minus Plug Pin Gage 21.26mm

Product Description

The VERMONT GAGE 112221260 is a Class ZZ Minus plug pin gage used to perform NoGo inspection checks on machined bores and holes. It delivers a diameter measurement of 21.26 mm with a tolerance of 0.00508 mm, providing the precision required for production-floor and quality-control applications. Constructed from steel with a 10 micro-inch coating finish, it is built to withstand repeated use in inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST standards, satisfying documentation requirements for ISO-compliant inspection programs. Metrologists, machinist inspectors, and quality technicians are the primary users of this gage.

This plug pin gage is suited for NoGo inspection of holes and bores in both production and tool-room settings. It is also compatible with setup and calibration procedures for micrometers, verniers, and other precision measuring devices. The 21.26 mm diameter and overall length of 2 inches make it practical for use in compact or standard bench-top inspection fixtures. It is appropriate for facilities operating under tight dimensional tolerances where NIST-traceable documentation is required for compliance or audit purposes.

Key Features

• Class ZZ Minus tolerance class for NoGo inspection applications
• 21.26 mm measurement diameter with 0.00508 mm tolerance
• Steel construction with 10 micro-inch coating for wear and corrosion resistance
• Includes Certificate of Accuracy with NIST traceability for compliance documentation
• 2-inch overall length suits standard bench-top and fixture-based inspection setups
• Compatible with setup verification for micrometers, verniers, and other measuring devices

Compatibility

Designed for use in NoGo bore and hole inspection and for setting micrometers, verniers, and other precision measuring devices requiring a 21.26 mm reference diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and inspection personnel. Clean the gage and the part bore thoroughly before use to prevent contamination from affecting measurement accuracy. Store the gage in its protective case when not in use to avoid nicks or corrosion that could compromise the tolerance surface. Do not force the gage into a bore - proper Class ZZ NoGo inspection relies on the gage not entering the feature.
