Vermont Gage 111160300 Class Zz Plus Plug Gage 0.603 in

Product Description

The VERMONT GAGE 111160300 is a Class ZZ Plus plug gage designed for precision go inspection of bored, drilled, and reamed holes at a nominal diameter of 0.603 inches. Manufactured from tool steel, this gage holds a tolerance of 0.0002 inches and features a 10 microfinish surface, delivering the dimensional accuracy required for shop-floor and quality-lab verification. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements common in ISO and AS9100 environments. The 2.0-inch overall length suits standard gage handle use. Machinists, quality technicians, and metrology professionals use this gage to verify whether a hole feature has been machined within its allowable go-limit boundary.

This plug gage is suited for go inspection tasks in production machining, toolroom, and quality control settings. It works directly with calibrated gage handles and is appropriate for use as a reference when setting micrometers, verniers, and other measuring devices to a known diameter. The Class ZZ Plus designation reflects a tighter tolerance class relative to standard Class ZZ gages, making it well suited for applications that demand higher confidence in dimensional conformance. Typical users include CNC machinists, quality inspectors, and metrology technicians working with close-tolerance hole features in ferrous and non-ferrous components.

Key Features

• 0.603-inch nominal diameter with 0.0002-inch tolerance for precise go-limit inspection
• 10 microfinish surface reduces wear and ensures consistent contact with the workpiece bore
• Tool steel construction provides durability under repeated use in production environments
• Includes Certificate of Accuracy with NIST traceability for audit and calibration documentation
• Conforms to ASME B89.1 standards for plain gages
• 2.0-inch overall length compatible with standard plug gage handles

Compatibility

Designed for use with standard plug gage handles and suitable for go inspection of holes with a nominal diameter of 0.603 inches. Also used as a setting reference for micrometers, verniers, and other measuring devices per the application data provided.

Installation Notes

Plug gages should be handled and stored by trained metrology or quality personnel following ASME B89.1 guidelines. Clean the gage and the workpiece bore before use to prevent false readings caused by chips, coolant, or debris. Never force the gage member into a hole; go-limit acceptance requires that the gage enter under its own weight or with light hand pressure only. Inspect the gage periodically for wear and return it to calibration on a schedule appropriate to usage frequency and your quality system requirements.
