Vermont Gage 111349950 Class Zz Plus Plug Gage 0.4995 in

Product Description

The VERMONT GAGE 111349950 is a Class ZZ Plus plug gage designed to verify bore diameters with high-precision go inspection. Manufactured from tool steel with a 10 microfinish surface, this plug gage measures a nominal diameter of 0.4995 inches with a tolerance of 0.0002 inches. It has an overall length of 2.0 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for quality control environments where documentation is required by calibration or inspection standards. Licensed metrologists, machinists, and quality technicians are the primary users of this type of gaging tool.

This plug gage is used in dimensional inspection of machined bores, holes, and cylindrical features in manufacturing and fabrication settings. It performs go inspection to confirm that a bore meets minimum size requirements. Beyond direct bore checking, it is also suitable for setting and verifying micrometers, vernier calipers, and other measuring devices. It is appropriate for both production floor inspection and metrology lab use where ASME B89.1 compliance is required.

Key Features

• Nominal measurement diameter of 0.4995 inches for precise bore verification
• Tolerance of 0.0002 inches per Class ZZ Plus classification
• 10 microfinish surface for accurate, low-wear contact during inspection
• Tool steel construction for durability and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for documentation requirements
• Conforms to ASME B89.1 standards for dimensional gaging

Compatibility

Designed for go inspection of bores and holes at a nominal 0.4995-inch diameter; also suitable for setting micrometers, verniers, and other precision measuring devices as specified in the product application data.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection environments. Before use, clean the gage and the bore being inspected to remove chips, oil, or debris that could affect the measurement. Do not force the gage into an undersized bore, as this will damage the gage surface and compromise its accuracy. Store the gage in its protective case when not in use to prevent corrosion and surface damage to the tool steel.
