Vermont Gage 112307050 Class Zz Plus Plug Gage 7.05mm

Product Description

The VERMONT GAGE 112307050 is a Class ZZ Plus plug gage designed for precision go inspection of bored, reamed, and drilled holes at a 7.05 mm diameter. Manufactured from tool steel with a 10 microfinish surface, this gage delivers a tolerance of 0.00508 mm, making it suitable for quality control environments where dimensional accuracy is critical. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in ISO and AS9100 regulated shops. Machinists, quality technicians, and metrology lab personnel use this tool as a standard component in go/no-go inspection routines.

This plug gage is used in machine shops, manufacturing facilities, and inspection labs for verifying hole diameters to ASME B89.1 standards. It is compatible with standard gage handle systems and is suitable for use alongside set micrometers, verniers, and other measuring devices. With an overall length of 2.0000 inches, it fits comfortably in handheld inspection setups on the shop floor or at a metrology bench. Applications span general metalworking, aerospace component inspection, and precision machining verification.

Key Features

• Class ZZ Plus tolerance rating at 0.00508 mm for precision go inspection
• Tool steel construction provides durability under repeated use
• 10 microfinish surface finish minimizes measurement error from surface irregularities
• Complies with ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• Compatible with standard gage handles and bench-top measuring setups

Compatibility

Designed for use in go inspection applications alongside set micrometers, verniers, and other precision measuring devices per ASME B89.1. Fits standard gage handle systems accepting a 7.05 mm plug gage.

Installation Notes

Plug gages are handled and used by quality technicians and machinists trained in dimensional inspection. Clean the gage and the workpiece bore thoroughly before use to prevent debris from affecting the measurement result. Do not force the gage into an undersized hole, as this can damage the gage surface and compromise calibration. Store the gage in its case and avoid contact with abrasive surfaces to maintain the 10 microfinish rating.
