Vermont Gage 112310990 Class Zz Plus Plug Gage 10.99 Mm

Product Description

The VERMONT GAGE 112310990 is a Class ZZ Plus plug gage manufactured from tool steel and used to verify bore diameters in precision machining and quality-control environments. This gage checks whether a hole falls within acceptable dimensional limits using a Go inspection method, confirming that a bore is not undersized. It measures 10.99 mm in diameter and holds a tolerance of 0.005 mm, making it appropriate for work requiring tight dimensional verification. The overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in ISO or AS9100 quality systems. Machinists, toolroom technicians, and quality inspectors are the primary users.

This plug gage is intended for Go inspection use on bored, drilled, or reamed holes nominally sized at 10.99 mm. It is compatible with standard gage handle sets and works alongside micrometers, verniers, and other measuring devices when verifying part conformance on production floors, tool rooms, or inspection stations. Typical applications include incoming inspection, in-process quality checks, and final part acceptance in both job-shop and high-volume manufacturing environments. The 10 microfinish surface coating reduces wear during repeated insertions and helps maintain dimensional accuracy over the service life of the gage.

Key Features

• Class ZZ Plus tolerance grade with 0.005 mm tolerance for precise Go inspection
• 10.99 mm nominal diameter for direct bore verification
• Tool steel construction for wear resistance in production environments
• 10 microfinish surface coating extends service life and protects gage accuracy
• Certificate of Accuracy included with NIST traceability for quality-system compliance
• Conforms to ASME B89.1 dimensional standards

Compatibility

Designed for use with standard plug gage handles and compatible with micrometers, verniers, and other measuring devices used in Go inspection applications for 10.99 mm nominal bore diameters.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no installation in the traditional sense applies, but proper gage practice requires clean, burr-free holes before insertion. Never force the gage into a bore, as this can damage the gage surface and produce false readings. Store the gage in its case when not in use to protect the lapped surface and maintain NIST-traceable accuracy. Follow your facility calibration schedule and ASME B89.1 handling guidelines to preserve the Certificate of Accuracy.
