Vermont Gage 112124000 Class Zz Plus Plug Gage 24mm

Product Description

The VERMONT GAGE 112124000 is a Class ZZ Plus plug gage designed for go-inspection of 24 mm diameter bores and holes. Machined from tool steel and finished to a 10 microinch surface finish, this gage delivers a tolerance of 0.005 mm, making it suitable for dimensional verification tasks where repeatable accuracy is required. It includes a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Machinists, quality technicians, and inspection personnel use this type of gage to confirm that a bore meets its minimum acceptable size before a part advances through production or assembly.

This plug gage is applied in go-inspection scenarios to verify that a 24 mm bore is within specification. It is also used to set and calibrate micrometers, verniers, and other measuring devices in a shop or inspection room environment. The overall length of 2 inches makes it a compact, handleable tool suited for both bench use and in-process checks on machined components. Industrial manufacturing, toolrooms, and quality labs are the typical settings where this gage sees regular use.

Key Features

• Class ZZ Plus tolerance of 0.005 mm for reliable go-inspection of 24 mm diameter features
• Tool steel construction for wear resistance and dimensional stability
• 10 microinch surface finish provides consistent, low-friction gage contact
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documentation and audit compliance
• Compact 2-inch overall length suits bench and in-process inspection use

Compatibility

Designed as an OEM-style go plug gage for 24 mm diameter bore inspection, and suitable for use as a setting standard with micrometers, verniers, and other precision measuring devices in shop or laboratory environments.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Clean the gage and the bore being checked before use to prevent debris from affecting the reading or damaging the gage surface. Apply light, consistent hand pressure when inserting the gage — never force it into a bore. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity.
