Vermont Gage 112101900 Class Zz Plus Plug Gage 1.9 Mm

Product Description

The VERMONT GAGE 112101900 is a Class ZZ Plus plug gage designed for precise dimensional verification of small-diameter bores and holes. With a nominal diameter of 1.9 mm and a tolerance of 0.005 mm, this gage delivers the accuracy required for go inspection of machined components. Manufactured from tool steel with a 10 microfinish surface, it provides consistent, repeatable measurement results. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and tool-room professionals use this gage as part of a calibrated inspection workflow.

This plug gage is suited for go inspection applications in precision machining environments, quality control labs, and production floor inspection stations. It is compatible with use alongside set micrometers, verniers, and other calibrated measuring devices. The 1.9 mm diameter makes it appropriate for checking tight-tolerance bores in small components such as those found in instrumentation, pneumatic fittings, and precision mechanical assemblies. Its compact overall length of 2.0 inches allows easy handling in confined inspection setups.

Key Features

• Class ZZ Plus tolerance grade with 0.005 mm tolerance for high-accuracy go inspection
• Tool steel construction provides durability and dimensional stability under repeated use
• 10 microfinish surface finish minimizes wear on the gage and the part being checked
• Includes Certificate of Accuracy with NIST traceability per ASME B89.1
• Compact 2.0-inch overall length suits tight inspection spaces

Compatibility

Designed for go inspection use with set micrometers, verniers, and other calibrated measuring devices in applications requiring verification of 1.9 mm diameter bores.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following standard metrology practices. Store the gage in its protective case when not in use to prevent damage to the lapped surface. Clean the gage and the part bore with a lint-free cloth before inspection to avoid false readings caused by debris or oil film. Follow your facility's calibration interval schedule and handle with care to preserve NIST-traceable accuracy.
