Vermont Gage 112310750 Class Zz Plus Plug Gage 10.75 Mm

Product Description

The VERMONT GAGE 112310750 is a Class ZZ Plus plug gage designed for go inspection of machined bores and holes. Ground from tool steel to a diameter of 10.75 mm with a tolerance of 0.00508 mm, this gage delivers the close-tolerance accuracy required for production inspection and quality control work. The 10 microfinish surface minimizes wear on the part being gauged and supports repeatable measurement. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, toolroom techs, and quality inspectors use this type of plug gage to verify that a bore falls within the acceptable go limit before a part advances through production.

This plug gage is suited for use in production and inspection environments where bore diameter verification is required. It is used alongside micrometers, verniers, and other measuring devices to confirm dimensional conformance. The 10.75 mm diameter makes it applicable to medium-small bore work common in precision machined components. At an overall length of 2.0000 inches, the handle provides a practical grip for bench and line inspection tasks in both job shop and manufacturing settings.

Key Features

• Class ZZ Plus tolerance classification per ASME B89.1 for go inspection applications
• 10.75 mm diameter ground to 0.00508 mm tolerance for precise bore verification
• 10 microfinish surface reduces wear and supports repeatable contact
• Tool steel construction for durability in production inspection environments
• Includes Certificate of Accuracy with NIST traceability
• Compatible with use alongside micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection use with micrometers, verniers, and other measuring devices where a 10.75 mm bore diameter must be verified to Class ZZ Plus tolerance per ASME B89.1.

Installation Notes

Plug gages are handled and deployed by machinists, toolroom technicians, and quality control inspectors. Before use, verify the gage and workpiece are at the same ambient temperature to avoid thermal expansion errors. Do not force the gage through a bore; apply only light hand pressure to prevent damage to the gage or the part. Store the gage with the included certificate and keep it clean and lightly oiled when not in use to prevent corrosion of the tool steel.
