Vermont Gage 112305670 Class Zz Plus Plug Gage 5.67mm

Product Description

The VERMONT GAGE 112305670 is a Class ZZ Plus plug gage designed for precision bore and hole inspection in manufacturing and metrology environments. The gage measures 5.67 mm in diameter and holds a tolerance of 0.00508 mm, providing reliable Go inspection capability for verifying that machined holes fall within specified dimensional limits. The tool steel construction and 10 microfinish surface finish ensure consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming that the gage meets ASME B89.1 standards. Machinists, quality control technicians, and metrology professionals use this gage as part of a structured inspection routine.

This plug gage is suited for Go inspection applications in precision machining, tool and die, and quality assurance settings. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices. The 5.67 mm diameter targets bore sizes common in small-component manufacturing, making it a practical addition to inspection kits on the shop floor or in a calibration lab. The overall length of 2.0000 inches provides adequate handling clearance in most standard inspection fixtures.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for tight dimensional control
• 5.67 mm diameter for Go inspection of small bored holes and machined features
• 10 microfinish surface finish for accurate, low-distortion contact
• Tool steel construction for durability and wear resistance in production use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards

Compatibility

Designed for use in Go inspection applications and for setting micrometers, verniers, and other measuring devices requiring a precise 5.67 mm reference diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists - no power source or mechanical installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel. Avoid dropping or striking the gage, as impact can alter the calibrated diameter and invalidate the NIST-traceable accuracy certification. Recalibration intervals should follow your facility's quality management procedures and applicable metrology standards.
