Vermont Gage 111115400 Class Zz Plus Plug Gage 0.154 in

Product Description

The VERMONT GAGE 111115400 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore and hole dimensions with high repeatability. It measures a nominal diameter of 0.154 inches with a tolerance of 0.0002 inches and features a 10 microfinish surface, which supports accurate contact with the workpiece. The gage ships with a Certificate of Accuracy that carries NIST traceability, confirming it meets ASME B89.1 standards. Machinists, quality control technicians, and metrology professionals use this gage for go inspection checks in production and inspection environments where tight dimensional control is required.

This plug gage is suited for go inspection of drilled, reamed, or bored holes at 0.154 inches nominal diameter. It is also used to set and verify micrometers, verniers, and other measuring devices in shop or lab environments. The 0.0002-inch tolerance class and 10 microfinish make it appropriate for precision work in both manufacturing and toolroom settings. The overall length of 2.0 inches gives the gage adequate reach for typical shallow-bore inspection tasks on production floors and in inspection rooms.

Key Features

• 0.154-inch nominal measurement diameter for go inspection of close-tolerance bores
• 0.0002-inch tolerance meets Class ZZ Plus precision requirements
• 10 microfinish surface for consistent, repeatable contact
• Tool steel construction for hardness and wear resistance
• Includes Certificate of Accuracy with NIST traceability
• Complies with ASME B89.1 dimensional gage standards

Compatibility

Designed for go inspection of holes and bores at 0.154 inches nominal diameter, and for use as a reference standard when setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and do not require installation in the traditional sense. Before use, clean the gage and the workpiece bore with a lint-free cloth to remove any debris or oils that could affect the measurement. Store the gage in its protective case when not in use to prevent wear or corrosion, and re-verify calibration periodically against the supplied NIST-traceable certificate to maintain measurement integrity.
