Vermont Gage 112302650 Class Zz Plus Plug Gage 2.65mm

Product Description

The VERMONT GAGE 112302650 is a Class ZZ Plus plug gage designed for dimensional inspection of holes and bores at a nominal diameter of 2.65 mm. Manufactured from tool steel and finished to a 10 microfinish surface, this gage holds a tolerance of 0.005 mm, meeting ASME B89.1 standards. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated inspection environments. Dimensional inspection technicians, quality control personnel, and toolroom professionals use this type of gage to verify whether a feature falls within acceptable limits before assembly or shipment.

This plug gage is suited for go inspection applications in light manufacturing, machining, and metrology environments. It is also used as a reference standard for setting micrometers, verniers, and other measuring devices. The 2.65 mm diameter places it in the small-bore range, appropriate for precision components in aerospace, medical, and general machining applications where tight tolerances must be verified at the workpiece level.

Key Features

• Class ZZ Plus tolerance grade: 0.005 mm, conforming to ASME B89.1
• 10 microfinish surface for consistent, accurate contact with the bore
• Tool steel construction for durability and wear resistance
• Includes Certificate of Accuracy with NIST traceability
• Designed for go inspection use and as a setting standard for measuring instruments
• Compact overall length of 2.0 inches suits bench and handheld inspection setups

Compatibility

Designed for go inspection of features at 2.65 mm nominal diameter and for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard at this diameter.

Installation Notes

Plug gages are handled and used by quality control technicians and toolroom machinists; no power source or mechanical installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Do not force the gage into a bore, as this will accelerate wear and can damage the workpiece or the gage. Store in a protective case away from temperature extremes to maintain dimensional stability and preserve the Certificate of Accuracy.
