Vermont Gage 111109100 Class Zz Plus Plug Gage 0.091 in

Product Description

The VERMONT GAGE 111109100 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes at 0.091 inches. Manufactured from tool steel with a 10 microfinish surface, this gage delivers the tight tolerances required for Go inspection work. The tolerance is held to 0.0002 inches, making it suitable for applications where close-fit verification is critical. A Certificate of Accuracy with NIST traceability is included, supporting quality documentation requirements on the shop floor or in a calibration lab. Dimensional inspection technicians, machinists, and quality control personnel are the primary users.

This plug gage is used in manufacturing and metrology environments to verify bore diameter acceptance during Go inspection routines. It is compatible with standard gage handle holders for efficient hand-held use. Typical applications include checking drilled, reamed, or machined bores in production settings. The gage is also referenced against set micrometers, verniers, and other precision measuring devices as a calibration reference standard. At 2.0 inches overall length, the gage fits standard small-pin gage handles used in both bench and in-process inspection setups.

Key Features

• Class ZZ Plus tolerance grade held to 0.0002 inches for precise Go inspection
• 10 microfinish surface for consistent, low-wear contact with bore walls
• Tool steel construction for durability in repetitive inspection cycles
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Conforms to ASME B89.1 dimensional gage standards
• 2.0 inches overall length suits standard small-pin gage handle systems

Compatibility

Designed for Go inspection of bores and holes, and for use as a reference with set micrometers, verniers, and other precision measuring devices per the manufacturer application data.

Installation Notes

Plug gages should be inserted into gage handle holders by qualified inspection or metrology personnel following shop calibration procedures. Clean the gage and the bore to be inspected before use to prevent debris from affecting the reading or damaging the gage surface. Store the gage in its protective case when not in use to preserve the microfinish and prevent corrosion on the tool steel body. Handle with clean, dry hands or lint-free gloves to avoid surface contamination that could affect measurement accuracy.
