Vermont Gage 112102900 Class Zz Plus Plug Gage 2.9mm

Product Description

The VERMONT GAGE 112102900 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore diameters in precision inspection applications. It has a nominal diameter of 2.9 mm and holds a tolerance of 0.00508 mm, making it suitable for go-inspection routines where tight dimensional control is required. The gage features a 10 microfinish surface and comes with a Certificate of Accuracy traceable to NIST. Overall length is 2.0 inches. Licensed metrology technicians, quality control inspectors, and toolroom machinists use this gage as part of standard dimensional verification workflows.

This plug gage is used in go inspection of small-bore features in production and toolroom environments. It is appropriate for use alongside set micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical applications include incoming inspection, in-process quality checks, and calibration reference tasks in manufacturing facilities handling close-tolerance components.

Key Features

• Class ZZ Plus tolerance rating: 0.00508 mm for precise go-inspection
• 10 microfinish surface for consistent gage-to-bore contact
• Tool steel construction for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards
• Compact 2.0-inch overall length suited for small-bore applications

Compatibility

Designed for use as a go plug gage in bore inspection routines; compatible with set micrometers, verniers, and other measuring devices requiring a traceable reference standard for small-diameter features.

Installation Notes

Plug gages are handled and used by quality technicians and toolroom professionals following ASME B89.1 inspection protocols. Store the gage in its case when not in use to prevent surface damage and corrosion. Clean the gage and the bore being checked before use to avoid false readings caused by debris or oil film. Never force the gage into a bore; apply only light, controlled hand pressure during inspection.
