Vermont Gage 111135600 Class Zz Plus Plug Gage 0.356 in

Product Description

The VERMONT GAGE 111135600 is a Class ZZ Plus plug gage used to verify bore and hole dimensions to a diameter of 0.356 inches. Built from tool steel, it delivers a tolerance of 0.0002 inches and a surface finish of 10 microinch, making it suitable for Go inspection applications where precise dimensional verification is required. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage to qualify production parts and calibrate measuring instruments.

This plug gage is used in manufacturing and inspection environments where accurate small-bore verification is essential. Typical applications include Go inspection of drilled, reamed, or bored holes, as well as setting and verifying micrometers, verniers, and other precision measuring devices. The 0.356-inch diameter and 2.0-inch overall length make it well suited for bench-top or in-process inspection work in machine shops, quality labs, and toolrooms.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy Go inspection
• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for wear resistance and dimensional stability
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0 inches for comfortable single-hand use

Compatibility

Designed as an OEM-style Go plug gage for use with bores and holes at a nominal diameter of 0.356 inches, and suitable for setting micrometers, verniers, and comparable precision measuring devices in standard inspection workflows.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power tools or utilities need to be shut down before use. Store the gage in its protective case when not in use and apply a light coat of instrument oil to prevent corrosion on the tool steel surfaces. Do not force the gage into an undersized bore, as this can damage the gage member and invalidate its calibration. Periodic recalibration against a NIST-traceable reference is recommended to maintain measurement integrity.
