Vermont Gage 112322390 Class Zz Plus Plug Gage 22.39 Mm

Product Description

The VERMONT GAGE 112322390 is a Class ZZ Plus plug gage designed for go inspection of bored, reamed, or machined holes with a nominal diameter of 22.39 mm. Manufactured from tool steel with a 10 micro-inch finish coating, this gage delivers a tolerance of 0.00508 mm, meeting the dimensional accuracy requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for calibrated inspection environments. It is used by quality control technicians, machinists, and metrologists to verify that a hole meets its minimum acceptable size before a mating part is assembled.

This plug gage is used in dimensional inspection applications across manufacturing, tool and die, and precision machining environments. It is compatible with go inspection workflows and can be used alongside set micrometers, verniers, and other measuring devices to confirm bore conformance. The 2.0-inch overall length provides adequate handle clearance for standard bench or inline inspection use. It is well-suited to production-floor quality checks as well as calibration lab verification tasks requiring NIST-traceable documentation.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for precise go inspection conformance
• Tool steel construction for wear resistance and dimensional stability
• 10 micro-inch surface coating for consistent gage contact and finish
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0 inches suits standard bench inspection setups

Compatibility

Designed for use in go inspection of machined holes at 22.39 mm nominal diameter and compatible with set micrometers, verniers, and other precision measuring devices per standard dimensional inspection practice.

Installation Notes

Plug gages are handled and used by quality control 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 on the tool steel surface. Do not force the gage into a hole that resists entry, as this can damage the gage or the workpiece. Store in the provided case or a protective sleeve to maintain calibration integrity between uses.
