Vermont Gage 112101560 Class Zz Plus Plug Gage 1.56 Mm

Product Description

The VERMONT GAGE 112101560 is a Class ZZ Plus plug gage designed for precise dimensional inspection of small-diameter bores and holes. The gage measures 1.56 mm in diameter with a tolerance of 0.00508 mm, making it suitable for high-accuracy go inspection applications. Manufactured from tool steel and finished to a 10 microfinish surface quality, this gage delivers consistent, repeatable measurements. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming conformance to ASME B89.1 standards. Machinists, quality control technicians, and metrology professionals use this type of gage to verify that bored or drilled features fall within specified dimensional limits.

This plug gage is used in go inspection tasks where confirming minimum acceptable bore size is required. It is compatible with use alongside set micrometers, verniers, and other precision measuring devices. Typical applications include incoming inspection, in-process quality checks on machined components, and final part verification in manufacturing and job shop environments. The small 1.56 mm diameter makes it particularly relevant for inspecting fine bores, pilot holes, and precision-drilled features in metal or plastic components.

• Includes Certificate of Accuracy with NIST Traceability per ASME B89.1
• Overall length of 2.0000 inches for comfortable handling and proper gage reach

Compatibility

Suitable for use as a go inspection gage alongside set micrometers, verniers, and other precision measuring devices per the application data provided by the manufacturer.

Installation Notes

Plug gages of this type are handled and used by metrology technicians, machinists, and quality inspectors rather than installed in a mechanical system. Clean the gage and the bore being checked before use to avoid measurement errors caused by debris or oil film. Do not force the gage into an undersized bore, as this can damage the gage surface and affect calibration. Store the gage in its protective case when not in use to preserve the microfinish and dimensional integrity.
