Vermont Gage 111180500 Class Zz Plus Plug Gage 0.805 in

Product Description

The VERMONT GAGE 111180500 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes and machined features. Manufactured from tool steel, this plug gage has a measurement diameter of 0.805 inches and a tolerance of 0.0002 inches. The contact surface carries a 10 microinch finish, supporting reliable, repeatable gaging results. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Quality technicians, machinists, and metrology lab personnel rely on this gage for go inspection tasks and for verifying the calibration of micrometers, verniers, and other precision measuring devices.

This plug gage is suited for go inspection applications in manufacturing, machine shops, and quality control environments. It is used to verify that bored holes, reamed features, and precision machined bores fall within acceptable dimensional limits. The overall length of 2.0 inches makes it practical for bench-top and floor-level inspection setups. It also serves as a setting standard for comparators, set micrometers, and similar measuring instruments where a traceable reference is required.

Key Features

• Measurement diameter of 0.805 inches with a tolerance of 0.0002 inches
• 10 microinch surface finish for consistent, low-wear contact
• Tool steel construction for durability and dimensional stability
• Compliant with ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Suitable for go inspection and as a setting reference for precision instruments

Compatibility

Designed for go inspection of holes and bores at 0.805 inches nominal diameter. Also used as a setting standard for micrometers, verniers, and other precision measuring devices requiring a traceable reference at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion and protect the precision finish. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability.
