Vermont Gage 112101180 Class Zz Plus Plug Gage 1.18 Mm

Product Description

The VERMONT GAGE 112101180 is a Class ZZ Plus plug gage designed for precise go inspection of small-diameter bores and holes. Manufactured from tool steel with a 10 microfinish surface, it checks whether a 1.18 mm diameter feature meets minimum size requirements. The gage holds a tolerance of 0.005 mm, making it suitable for quality control workflows that demand tight dimensional verification. It ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in calibrated inspection environments. Metrology technicians, tool room inspectors, and quality assurance professionals are the primary users of this instrument.

This plug gage is used in go inspection applications across manufacturing, tool rooms, and quality labs. It is compatible with inspection routines involving micrometers, verniers, and other precision measuring devices where a physical reference standard is required. The 1.18 mm diameter targets fine-tolerance features common in machined components, medical device parts, and instrument manufacturing. Its compact overall length of 2 inches makes it easy to handle during bench or in-process inspection tasks.

Key Features

• Class ZZ Plus tolerance of 0.005 mm for tight dimensional control at 1.18 mm diameter
• Tool steel construction provides hardness and wear resistance appropriate for repeated gauging
• 10 microfinish surface finish minimizes gage wear on inspected features
• Includes Certificate of Accuracy with NIST traceability for calibrated inspection documentation
• Meets ASME B89.1 standards for plain plug gage design and tolerancing
• Compact 2-inch overall length suits bench and in-process inspection setups

Compatibility

Designed for use as a go plug gage reference standard with micrometers, verniers, and other precision measuring devices in go inspection applications per ASME B89.1.

Installation Notes

Plug gages are handled and used by metrology technicians and quality inspectors rather than installed in a mechanical system. Store the gage in its protective case when not in use to prevent surface damage. Clean the gage and the feature being inspected before use to avoid false readings caused by debris or oil film. Do not force the gage into a feature; excessive insertion force can damage both the gage and the workpiece.
