Vermont Gage 111165400 Class Zz Plus Plug Gage 0.654 in

Product Description

The VERMONT GAGE 111165400 is a Class ZZ Plus plug gage designed for precise go inspection of machined bores and holes at a nominal diameter of 0.654 inches. Built from tool steel, it holds a tolerance of 0.0002 inches and carries a 10 microfinish surface finish, making it suitable for quality control applications where dimensional accuracy is critical. The gage ships with a Certificate of Accuracy with NIST traceability, supporting compliance with documented inspection programs. It is used by machinists, quality technicians, and metrology personnel in production and inspection environments.

This plug gage is appropriate for go inspection of holes and bores measuring 0.654 inches in diameter. It is also suited for setting and verifying micrometers, verniers, and other measuring devices to a known reference diameter. The 2.0-inch overall length provides a practical handling geometry for bench or floor inspection work. It meets ASME B89.1 standards, making it appropriate for use in regulated manufacturing and quality assurance settings, including aerospace, automotive, and general precision machining shops.

Key Features

• Tool steel construction for durability and dimensional stability under repeated use
• Includes Certificate of Accuracy with NIST traceability for documented quality programs
• Meets ASME B89.1 standards
• 2.0-inch overall length for practical bench handling

Compatibility

Designed for go inspection of machined bores and holes at 0.654 inches diameter, and for use as a reference standard when setting micrometers, verniers, and other measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or trade license is required for use. Store the gage in a protective case away from contaminants and temperature extremes to preserve dimensional integrity. Clean the gage and the bore being checked before each use to prevent debris from causing false readings or surface damage. Do not force the gage into an undersize bore, as this can damage both the gage and the workpiece.
