Vermont Gage 112124900 Class Zz Plus Plug Gage 24.9mm

Product Description

The VERMONT GAGE 112124900 is a Class ZZ Plus plug gage designed to verify bore diameters with high precision in production and inspection environments. Machined from tool steel with a 10 microfinish surface, it provides repeatable go-inspection results at a 24.90 mm nominal diameter and a tolerance of 0.00508 mm. Each unit ships with a Certificate of Accuracy that includes NIST traceability, making it suitable for quality-system documentation requirements under ASME B89.1. Metrology technicians, toolroom machinists, and quality inspectors use this gage as part of calibrated measurement workflows.

This plug gage is used for go inspection of 24.90 mm diameter bores in precision machining and manufacturing settings. It is also suited for setting micrometers, verniers, and other measuring devices to a known reference diameter. Typical applications include incoming inspection, first-article inspection, and in-process quality checks on machined components where bore diameter conformance must be documented to a traceable standard.

Key Features

• 24.90 mm nominal diameter with 0.00508 mm Class ZZ Plus tolerance
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for consistent, low-friction gage entry
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional standards
• Overall length of 2.0000 inches for standard handle compatibility

Compatibility

Designed for go inspection of 24.90 mm diameter bores and for use as a reference setting standard with micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by metrology or quality personnel, not installed in the field. Before use, clean the gage and the bore being inspected with a lint-free cloth to remove debris, oils, and chips that could affect readings. Never force the gage into a bore; apply light, consistent hand pressure only. Store the gage in its case away from magnetic fields and temperature extremes to maintain dimensional integrity.
