Vermont Gage 112111760 Class Zz Plus Plug Gage 11.76mm

Product Description

The VERMONT GAGE 112111760 is a Class ZZ Plus plug gage machined from tool steel for go-type bore inspection. It measures 11.76 mm in diameter with a tolerance of 0.00508 mm, making it suitable for precision inspection work where tight dimensional control is required. The gage features a 10 microfinish surface to minimize wear and ensure repeatable contact with the bore. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements common in ISO-registered and aerospace-adjacent shops. Dimensional inspectors, machinists, and quality technicians use this type of gage for verifying bore acceptance on production parts.

This plug gage is used in go inspection applications to confirm that a bore meets its minimum acceptance limit. It is appropriate for use alongside set micrometers, verniers, and other measuring devices in quality control workflows. The gage is manufactured to ASME B89.1 standards, which govern the dimensional and tolerance requirements for plain plug gages used in industrial and metrology environments. It is well suited for both job shop and production floor inspection routines where a traceable, calibrated reference is required.

Key Features

• Tool steel construction provides durability in production inspection environments
• Includes Certificate of Accuracy with NIST traceability to support quality documentation requirements
• Manufactured to ASME B89.1 standards

Compatibility

Designed for go inspection use with set micrometers, verniers, and other measuring devices per the application specifications provided by the manufacturer.

Installation Notes

Plug gages are handled and used by dimensional inspectors and machinists; no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the bore being inspected before use to avoid false readings caused by debris or cutting fluid residue. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.
