Vermont Gage 112100900 Class Zz Plus Plug Gage 0.9 Mm

Product Description

The VERMONT GAGE 112100900 is a Class ZZ Plus cylindrical plug gage designed for go inspection of small-bore holes and precision measurement applications. It has a nominal diameter of 0.9 mm with a tolerance of 0.00508 mm, making it suitable for high-precision quality control work. The gage features a 10 microfinish surface on the measuring element for consistent, repeatable contact. It is manufactured from tool steel for durability and wear resistance. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Metrology technicians, machinists, and quality control inspectors use this gage in production and inspection environments.

This plug gage is used to verify minimum acceptable bore diameters in small precision components. It is well suited for go inspection routines on machined parts, and it serves as a reference standard when setting micrometers, verniers, and other dimensional measuring devices. The 2.0-inch overall length fits standard gage handle holders, making it practical for bench inspection and in-process checks on production lines or in metrology labs.

Key Features

• 0.9 mm nominal diameter with 0.00508 mm tolerance for precise go inspection
• 10 microfinish surface for consistent, low-friction contact on bore walls
• Tool steel construction for long service life under repeated use
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• 2.0-inch overall length compatible with standard gage handle systems

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle holders in precision bore inspection of small machined components. Also suitable for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages of this type are handled and used by trained metrology personnel or quality control technicians. No power source is required. 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; damage to the gage or workpiece may result if the gage is driven rather than guided by hand.
