Vermont Gage 111116400 Class Zz Plus Plug Gage 0.164 in

Product Description

The VERMONT GAGE 111116400 is a Class ZZ Plus cylindrical plug gage used to verify bore and hole dimensions to a high degree of precision. Machined from tool steel with a 10 microfinish surface, this gage measures a diameter of 0.164 inches with a tolerance of 0.0002 inches. It is 2.0 inches in overall length, making it a compact, hand-held inspection tool. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming conformance to ASME B89.1 dimensional standards. Licensed metrologists, quality technicians, and toolroom machinists rely on plug gages of this class for go inspection tasks and calibration of measuring instruments.

This plug gage is suited for go inspection in precision manufacturing environments, toolrooms, and quality control labs. Its primary application is verifying that bored, drilled, or reamed holes fall within acceptable dimensional limits. It is also used as a calibration reference for setting micrometers, verniers, and other measuring devices where a known physical standard is required. The compact size accommodates tight workpiece geometries where larger instruments cannot be positioned accurately.

Key Features

• Class ZZ Plus tolerance grade at plus or minus 0.0002 inches for high-precision go inspection
• 10 microfinish surface for consistent, repeatable gage contact
• Tool steel construction for wear resistance and dimensional stability
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST Traceability
• Compact 2.0-inch overall length fits tight inspection scenarios

Compatibility

Designed for go inspection of holes and bores measuring 0.164 inches in diameter. Also suitable for use as a setting standard for micrometers, verniers, and other precision measuring devices requiring a physical dimensional reference.

Installation Notes

This gage is handled and used by quality technicians, metrologists, and toolroom personnel — no installation in a mechanical system is required. Store the gage in a protective case when not in use to prevent surface damage that could affect accuracy. Clean contact surfaces before each use and allow the gage to reach ambient room temperature before taking measurements to eliminate thermal expansion error. Handle with care to avoid dropping, as impact damage can alter dimensional accuracy and void traceability.
