Vermont Gage 112102540 Class Zz Plus Plug Gage 2.54mm

Product Description

The VERMONT GAGE 112102540 is a Class ZZ Plus plug gage designed for dimensional inspection of machined bores and holes at a 2.54 mm diameter. Built from tool steel with a 10 microfinish surface, this gage delivers a tolerance of 0.005 mm, making it suitable for go inspection applications where precise measurement verification is required. It includes a Certificate of Accuracy with NIST traceability, confirming the gage meets documented measurement standards. Machinists, quality control technicians, and metrologists use this type of gage as a fast, repeatable method to confirm whether a feature falls within specified dimensional limits.

This plug gage is used in shop-floor and metrology lab environments where go inspection is needed on small-diameter bores. It is also compatible with applications involving setting micrometers, verniers, and other measuring devices that require a calibrated reference. Typical install scenarios include incoming inspection, in-process quality checks, and final dimensional verification on precision machined components. The small diameter and compact form factor make it well suited for tight-tolerance work on small parts in both production and prototype settings.

Key Features

• Class ZZ Plus tolerance classification for go inspection accuracy
• 2.54 mm diameter with 0.005 mm tolerance
• 10 microfinish surface for consistent, repeatable contact measurement
• Tool steel construction for hardness and wear resistance in production use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards

Compatibility

Designed for go inspection applications and for use with setting micrometers, verniers, and other measuring devices requiring a calibrated plug reference at 2.54 mm diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; apply only light, controlled hand pressure to avoid damage to the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability and NIST-traceable calibration.
