Vermont Gage 112212800 Class Zz Minus Plug Pin Gage 12.80 Mm

Product Description

The VERMONT GAGE 112212800 is a Class ZZ minus plug pin gage used for precision dimensional inspection in machining and metrology applications. It measures 12.80 mm in diameter with a tolerance of 0.00508 mm, making it appropriate for NoGo inspection tasks where tight tolerance verification is required. The gage is machined from steel and carries a 10 micro-inch coating or finish for surface consistency. Overall length is 2 inches. A Certificate of Accuracy with NIST traceability is included, supporting quality control documentation requirements in calibrated inspection environments. Machinists, quality technicians, and metrologists are the primary users.

This gage is suited for use in production inspection lines, tool rooms, and quality labs. It is designed to work alongside micrometers, verniers, and other precision measuring devices as part of a NoGo inspection process. Class ZZ tolerancing places this gage in the category appropriate for general-purpose inspection rather than high-precision master gage applications. It is commonly used to verify that a hole or bore does not exceed its maximum allowable size limit.

Key Features

• 12.80 mm measurement diameter with 0.00508 mm tolerance for precise NoGo inspection
• Class ZZ minus designation for general-purpose plug gage inspection use
• Steel construction with 10 micro-inch coating for surface uniformity and wear resistance
• Certificate of Accuracy with NIST traceability included for calibration documentation
• Overall length of 2 inches for standard hand-held gage use
• Compatible with micrometers, verniers, and other precision measuring devices

Compatibility

Designed for NoGo inspection applications and for use with micrometers, verniers, and other precision measuring devices requiring a Class ZZ minus plug gage at 12.80 mm diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists in calibrated inspection environments. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel body. Do not force the gage into a bore; controlled hand pressure is the standard method. Store in a protective case away from temperature extremes to maintain dimensional stability and traceability integrity.
