Vermont Gage 112312670 Class Zz Plus Plug Gage 12.67mm

Product Description

The VERMONT GAGE 112312670 is a Class ZZ Plus plug gage designed for precise bore and hole diameter inspection. Built from tool steel with a 10 microfinish surface coating, it measures a nominal diameter of 12.67 mm with a tolerance of 0.005 mm (0.00508 mm). This gage is used in go inspection applications to verify that a hole or bore meets the minimum acceptable size. Machinists, quality control technicians, and toolroom personnel use plug gages like this one as part of standard dimensional verification workflows. Each unit ships with a Certificate of Accuracy traceable to NIST.

This plug gage is suited for use in manufacturing and machine shop environments where tight dimensional tolerances must be verified quickly and reliably. It is compatible with go inspection procedures and can be used alongside micrometers, verniers, and other measuring devices for comprehensive dimensional checks. The 2.0 inch overall length provides a practical form factor for handheld use during inspection of machined parts, castings, and fabricated components. It meets ASME B89.1 standards, making it appropriate for quality systems that require traceable, standardized tooling.

Key Features

• Class ZZ Plus tolerance grade with 0.005 mm tolerance for high-accuracy go inspection
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface coating for consistent, low-friction gauging contact
• Meets ASME B89.1 standards for dimensional gaging
• Includes Certificate of Accuracy with NIST traceability
• Compact 2.0 inch overall length for easy handheld use

Compatibility

Designed for go inspection use with micrometers, verniers, and other measuring devices in standard dimensional inspection applications per ASME B89.1.

Installation Notes

Plug gages are installed and used by machinists and quality control technicians as part of dimensional inspection — not as permanent installed components. Handle the gage by the handle body to avoid thermal expansion from hand contact on the gage member. Store in the provided case or a protected location to prevent surface damage. Calibration should be verified periodically against NIST-traceable standards to maintain measurement integrity.
