Vermont Gage 112301930 Class Zz Plus Plug Gage 1.93mm

Product Description

The VERMONT GAGE 112301930 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes at 1.93 mm diameter. Built from tool steel with a 10 microfinish surface, this gage delivers a tolerance of 0.005 mm, meeting the accuracy demands of quality control environments. It ships with a Certificate of Accuracy with NIST traceability, making it suitable for documented inspection programs. Machinists, quality technicians, and metrologists use this gage to verify hole size conformance during production runs and final inspection. It is a go-type inspection tool and does not function as a no-go gage independently.

This plug gage is used in applications requiring precise verification of small-diameter bores, including machined components, hydraulic fittings, and precision assemblies. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices as stated by the manufacturer. Typical use environments include machine shops, manufacturing quality labs, and toolroom inspection stations. The overall length of 2.0 inches makes it compact and easy to handle for repetitive inspection tasks.

Key Features

• Class ZZ Plus tolerance rating at 0.005 mm for high-accuracy go inspection
• Tool steel construction for durability and wear resistance in production use
• 10 microfinish surface for consistent, repeatable contact with inspected bores
• Includes Certificate of Accuracy with NIST traceability for documented QC programs
• Meets ASME B89.1 dimensional gage standards
• Compact overall length of 2.0 inches for easy single-hand operation

Compatibility

Designed for go inspection of 1.93 mm diameter bores and for use with micrometers, verniers, and other measuring devices as indicated by the manufacturer. Conforms to ASME B89.1 standards.

Installation Notes

Handle and store this gage in a clean, dry environment to prevent corrosion and measurement error. Always clean the gage and the bore being inspected before use to remove chips, oil, or debris that could affect accuracy. Do not force the gage into a bore; insertion should require only light, consistent hand pressure. Calibration intervals should follow your facility quality management procedures and applicable metrology standards.
