Vermont Gage 111307550 Class Zz Plus Plug Gage 0.0755 in

Product Description

The VERMONT GAGE 111307550 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes, drilled passages, and machined features. It measures a nominal diameter of 0.0755 inches with a tolerance of 0.0002 inches, making it suitable for close-tolerance go inspection work. The gage is machined from tool steel and finished to a 10 microfinish surface quality. A Certificate of Accuracy with NIST traceability is included, supporting quality documentation requirements in ISO- and AS9100-registered facilities. Machinists, quality technicians, and tool room personnel use this gage as part of attribute inspection routines or to verify and set micrometers, verniers, and other measuring devices.

This gage is suited for use in precision manufacturing, tool and die, aerospace, and general metalworking environments where controlled hole diameters must be verified to ASME B89.1 standards. Its overall length of 2.0 inches provides adequate reach for standard workpiece depths. The Class ZZ Plus designation indicates it meets tighter tolerance requirements than standard Class ZZ gages, making it appropriate for production inspection where dimensional variation must be tightly controlled.

Key Features

• Nominal measurement diameter of 0.0755 inches with 0.0002-inch tolerance
• Class ZZ Plus classification meets ASME B89.1 dimensional standards
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for accurate, repeatable contact with the workpiece
• Includes Certificate of Accuracy with NIST traceability for quality records
• Suitable for go inspection and calibration of measuring instruments

Compatibility

Designed for go inspection applications and for setting or verifying micrometers, verniers, and other measuring devices requiring a 0.0755-inch reference diameter.

Installation Notes

Plug gages should be handled with clean, dry hands or cotton gloves to prevent corrosion and measurement error from skin oils. Before use, inspect the gage and the workpiece bore for burrs, chips, or debris that could damage the gage surface or produce false readings. Apply light gaging oil when specified by the inspection procedure to reduce wear on high-cycle applications. Store the gage in its case away from heat sources and abrasive surfaces to maintain dimensional integrity.
