Vermont Gage 112123000 Class Zz Plus Plug Gage 23mm

Product Description

The VERMONT GAGE 112123000 is a Class ZZ Plus cylindrical plug gage machined from tool steel for go-type inspection of 23 mm diameter bored holes, machined bores, and similar internal features. It carries a tolerance of 0.00508 mm and a 10 microfinish surface, giving it the dimensional consistency required for setting micrometers, verniers, and other precision measuring devices. A Certificate of Accuracy with NIST traceability is included, supporting quality-system documentation requirements. Machinists, toolroom technicians, and quality control inspectors use this gage in production and incoming-inspection environments where tight bore tolerances must be verified quickly and reliably.

This plug gage is suited for go inspection tasks in metalworking, machining, and precision manufacturing operations. It is appropriate for both production floor and toolroom use where 23 mm nominal bore sizes require verification against ASME B89.1 standards. The included NIST-traceable certificate supports ISO 9001 and AS9100 quality programs. Overall length is 2.0000 inches, making it compatible with standard gage handle configurations for bench or in-line inspection setups.

Key Features

• Class ZZ Plus tolerance rating: 0.00508 mm for high-accuracy go inspection
• 10 microfinish surface for consistent, repeatable contact with bore surfaces
• Tool steel construction for wear resistance and dimensional stability
• Complies with ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Compatible with standard gage handle setups for 23 mm nominal bore inspection

Compatibility

Designed as a go-type plug gage for verifying 23 mm nominal diameter internal bores. Also suitable for setting micrometers, verniers, and other precision measuring devices requiring a certified reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and toolroom machinists. Store the gage in its case when not in use to prevent surface damage that could affect dimensional accuracy. Clean the bore and gage surfaces before use to remove chips, oils, or debris that could cause false readings or accelerate wear. Do not force the gage into an undersize bore; apply only light, steady hand pressure consistent with standard ASME B89.1 inspection practice.
