Vermont Gage 112216620 Class Zz Minus Plug Pin Gage 16.62mm

Product Description

The VERMONT GAGE 112216620 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection of bored, drilled, or reamed holes. It measures 16.62 mm in diameter with a tolerance of 0.00508 mm, delivering the dimensional precision required for production floor and metrology room verification. At 2 inches in overall length, this pin gage is sized for practical handling in both bench and in-process applications. Each unit ships with a Certificate of Accuracy that carries full NIST traceability, satisfying quality management and calibration documentation requirements. Machinists, quality technicians, and metrologists use this gage to verify that a feature has not exceeded its maximum material condition limit.

This pin gage is suited for NoGo hole inspection in manufacturing, tool-and-die, and precision machining environments, both in job shops and higher-volume production settings. It is also appropriate for setting and verifying micrometers, verniers, and other comparative measuring devices where a traceable reference standard is needed. The Class ZZ tolerance designation makes it a cost-effective choice for general-purpose inspection rather than master or working-gage applications requiring tighter Class X or XX tolerances.

Key Features

• Class ZZ Minus tolerance designation for NoGo inspection applications
• 16.62 mm measurement diameter with 0.00508 mm tolerance
• Steel construction for durability and dimensional stability
• Certificate of Accuracy included with NIST traceability for documentation compliance
• 2 inches overall length for comfortable handling in bench and in-process use
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for NoGo hole inspection and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a traceable 16.62 mm diameter reference.

Installation Notes

Pin gages are handled and stored by metrology or quality technicians; no mechanical installation is required. Always clean the gage and the feature under inspection before use to prevent measurement error or surface damage. Store in a protective case away from magnetic fields and temperature extremes to maintain dimensional stability. Calibration intervals should follow your facility quality management system and applicable standards.
