Vermont Gage 112301110 Class Zz Plus Plug Gage 1.11mm

Product Description

The VERMONT GAGE 112301110 is a Class ZZ Plus plug gage manufactured from tool steel, designed for precision dimensional inspection of small-diameter holes and bores. With a nominal diameter of 1.11 mm and a tolerance of 0.005 mm (0.00508 mm actual), this gage is engineered for Go inspection applications where tight measurement accuracy is required. The overall length is 2.0000 inches, making it suitable for bench use in production and quality control environments. A Certificate of Accuracy with NIST Traceability is included, supporting documentation requirements for ISO and AS9100 quality programs. Machinists, metrologists, and quality technicians use this gage to verify that drilled, reamed, or punched features fall within specified tolerance limits.

This plug gage is used in manufacturing and inspection environments where small-bore verification is performed against Go/No-Go criteria. It is appropriate for setting micrometers, verniers, and other measuring devices to a known reference diameter. Typical applications include incoming inspection, in-process quality checks, and calibration lab use. The 10 microfinish surface coating preserves dimensional integrity over repeated insertions and helps extend gage service life in high-cycle inspection routines. This gage meets ASME B89.1 standards, making it suitable for facilities operating under formal metrology or quality management protocols.

Key Features

• Tool steel construction for wear resistance and dimensional stability
• 10 Microfinish surface coating to maintain gage accuracy over repeated use
• Meets ASME B89.1 dimensional standards for plug gages
• Includes Certificate of Accuracy with NIST Traceability for documentation and compliance
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed for Go inspection of 1.11 mm diameter features. Compatible with standard gage handle sets and applicable to quality control workflows involving micrometers, verniers, and comparable precision measuring instruments per ASME B89.1.

Installation Notes

Plug gages are typically handled by quality technicians and metrologists; no power-down or lockout procedure is required for gage use. Store the gage in its protective case when not in use and avoid contact with abrasive surfaces that could alter the gage diameter. Clean the gage and the feature being inspected before use to prevent false readings caused by debris or coolant residue. Handle with clean cotton gloves or gage handling tools to prevent thermal expansion from hand contact from affecting measurement readings.
