Vermont Gage 111270100 Class Zz Minus Plug Pin Gage 0.7010 in

Product Description

The VERMONT GAGE 111270100 is a Class ZZ Minus plug pin gage machined to a nominal diameter of 0.7010 inches with a tolerance of 0.0002 inches. This single-end pin gage is used to verify that a hole or bore does not exceed its maximum allowable size — the NoGo function in a go/no-go inspection workflow. Overall length is 2 inches. Each gage ships with a Certificate of Accuracy traceable to NIST, supporting calibration documentation requirements in quality-controlled shops and inspection environments. The steel construction delivers the dimensional stability required for repeatable measurement in production and maintenance settings.

This pin gage is suited for dimensional inspection of drilled, reamed, or bored holes in both shop-floor and metrology lab environments. It is used alongside go gages, micrometers, verniers, and other precision measuring devices to confirm that machined features fall within tolerance. Typical applications include incoming inspection, in-process quality checks, and fixture verification. The Class ZZ designation indicates a commercial-grade tolerance appropriate for general-purpose inspection rather than master or reference gage use.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection applications
• Nominal diameter of 0.7010 inches with a 0.0002-inch tolerance
• Steel construction for dimensional stability and wear resistance
• 10 micro finish coating for consistent surface contact
• Includes Certificate of Accuracy with NIST traceability
• Compact 2-inch overall length for easy handling in tight inspection setups

Compatibility

Designed for use as a NoGo inspection gage and as a setting standard for micrometers, verniers, and other precision measuring devices requiring a 0.7010-inch reference diameter.

Installation Notes

Pin gages are handled and used by quality technicians and machinists — no installation in the traditional sense applies. Always clean the gage and the feature being measured before use to prevent false readings from debris or burrs. Store pin gages in a protective case away from other metal tools to avoid surface damage. Periodic recalibration against traceable standards is recommended to maintain measurement integrity.
