Vermont Gage 112102580 Class Zz Plus Plug Gage 2.58mm

Product Description

The VERMONT GAGE 112102580 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes. Built from tool steel and finished to a 10 microfinish surface quality, this gage provides a reliable go-inspection reference at a 2.58 mm nominal diameter with a tolerance of 0.00508 mm. It is used to verify that a drilled, reamed, or bored feature meets minimum acceptable size requirements. A Certificate of Accuracy with NIST traceability is included, supporting calibration records and quality system documentation. Licensed metrologists, quality technicians, and tool-and-die professionals are the typical users of this type of gage.

This plug gage is suited for production floor inspection, incoming inspection stations, and calibration lab environments where go-type attribute gaging is required. It is appropriate for checking small-diameter features in precision machined components across manufacturing, tool-and-die, and metrology applications. The gage is also compatible with use alongside set micrometers, verniers, and other measuring devices for comparative measurement setups. Its compact size makes it practical for both bench-top and in-process inspection workflows.

Key Features

• Class ZZ Plus tolerance classification for go-type attribute inspection
• 2.58 mm nominal diameter with 0.00508 mm tolerance
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface finish for accurate, repeatable contact
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for calibration records

Compatibility

Designed for go-type inspection use with set micrometers, verniers, and other precision measuring devices in applications requiring ASME B89.1 compliant plug gaging at the 2.58 mm diameter range.

Installation Notes

Plug gages of this type are handled and used by quality technicians and metrologists rather than installed in a mechanical system. 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 feature; go gages should pass under the weight of the gage or light hand pressure only. Store in the supplied case or a protective holder away from other metal tools to avoid contact damage to the finished surface.
