Vermont Gage 112301750 Class Zz Plus Plug Gage 1.75 Mm

Product Description

The VERMONT GAGE 112301750 is a Class ZZ Plus plug gage designed for precise dimensional inspection of small bores and holes. Built from tool steel with a 10 microfinish surface coating, this gage delivers a tolerance of 0.005 mm, making it suited for go inspection tasks where tight measurement accuracy is required. With an overall length of 2.0 inches, it is compact enough for bench use and field calibration work. Metrologists, quality control technicians, and precision machinists rely on this type of gage to verify hole diameters against ASME B89.1 standards. Each unit ships with a Certificate of Accuracy that includes NIST traceability.

This plug gage is used in manufacturing and quality assurance environments where bore diameter conformance must be verified. At 1.75 mm diameter, it targets small-hole inspection applications common in precision machining, tooling, and instrument manufacturing. It is also compatible with setup and calibration of micrometers, verniers, and other measuring devices. Shops performing high-volume go inspection benefit from the consistent geometry and certified accuracy of this gage class.

• Compact 2.0-inch overall length suits bench and portable inspection use

Compatibility

Suitable for go inspection of 1.75 mm diameter bores and for use in setting and verifying micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality control technicians and precision metrology personnel. 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 bore; apply only light, steady hand pressure to avoid damage to the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
