Vermont Gage 112111000 Class Zz Plus Plug Gage 11mm

Product Description

The VERMONT GAGE 112111000 is a Class ZZ Plus cylindrical plug gage manufactured from tool steel for use in precision dimensional inspection. It checks whether a bored or reamed hole meets the minimum acceptable diameter - the go condition - in quality control and machining workflows. The gage measures 11.00 mm in diameter with a tolerance of 0.00508 mm and a 10 microfinish surface finish. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting documented inspection programs and calibration records. Machinists, quality technicians, and metrology professionals use this tool as part of go/no-go inspection routines.

This plug gage is suited for go inspection on machined holes in production and job-shop environments. It is designed for use alongside micrometers, verniers, and other measuring devices to confirm hole diameter conformance. The Class ZZ Plus tolerance class makes it appropriate for inspection-grade checking rather than master or working gage applications. It fits standard gage handle holders used in benchtop and floor-level inspection setups in both light manufacturing and precision machining facilities.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for inspection-grade accuracy
• 11.00 mm diameter for go inspection of bored, drilled, or reamed holes
• 10 microfinish surface finish for consistent contact and reduced wear on the gage surface
• Tool steel construction for durability in repeated-use inspection environments
• Includes Certificate of Accuracy with NIST traceability for documented quality programs
• Conforms to ASME B89.1 standards

Compatibility

Designed for use with standard plug gage handles and holders compatible with 11.00 mm diameter gage blanks. Suitable for go inspection tasks performed with micrometers, verniers, and other dimensional measuring devices as noted in the product application data.

Installation Notes

This gage is handled by quality technicians and machinists during in-process or final inspection - no installation in a mechanical system is required. Clean and inspect the gage surface before each use to prevent debris from affecting measurement accuracy. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity. Follow your facility calibration schedule and retain the NIST-traceable certificate for audit compliance.
