Vermont Gage 111315350 Class Zz Plus Plug Gage 0.1535 in

Product Description

The VERMONT GAGE 111315350 is a Class ZZ Plus plug gage designed for precise go inspection of bored, drilled, and reamed holes at a nominal diameter of 0.1535 inches. Built from tool steel with a 10 microfinish surface, it delivers reliable dimensional verification in quality control and inspection environments. The gage holds a tolerance of 0.0002 inches, meeting the requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy that includes NIST traceability, supporting documented inspection records and calibration compliance. Machinists, quality technicians, and metrology professionals use this type of gage as a fast, repeatable pass-or-fail check on machined features.

This plug gage is suited for go inspection workflows in manufacturing and machine shop environments. At 0.1535 inches diameter and 2.0 inches overall length, it fits standard gage handle systems and works alongside set micrometers, verniers, and other precision measuring devices as a reference standard. Typical applications include incoming inspection, in-process quality checks, and final part verification where a definitive dimensional pass-or-fail result is required. The NIST-traceable certificate makes it appropriate for AS9100, ISO 9001, and similar quality management environments that require documented traceability.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for reliable go inspection at 0.1535 inches diameter
• Tool steel construction provides hardness and wear resistance for repeated use
• 10 microfinish surface finish reduces friction and wear during inspection
• Complies with ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• Compact 2.0 inch overall length fits standard plug gage handles

Compatibility

Designed for use with standard plug gage handle systems and compatible with set micrometers, verniers, and other precision measuring devices as noted by the manufacturer. Suitable for go inspection of machined holes at 0.1535 inches nominal diameter.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists in controlled inspection environments. Store the gage in its protective case when not in use to prevent damage to the precision ground surface. Apply a light film of instrument oil before storage to protect against corrosion. Never force the gage into a bore; go gages should enter under the weight of the gage alone or with minimal hand pressure.
