Vermont Gage 111321250 Class Zz Plus Plug Gage 0.2125 in

Product Description

The VERMONT GAGE 111321250 is a Class ZZ Plus plug gage designed for precision go inspection of bored, drilled, and reamed holes. Manufactured from tool steel with a 10 microfinish surface, it measures a nominal diameter of 0.2125 inches with a tolerance of 0.0002 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming dimensional compliance to ASME B89.1 standards. Machinists, quality technicians, and tool-room professionals use this gage to verify hole sizes quickly and reliably in production and inspection environments.

This plug gage is suited for go inspection applications across light manufacturing, precision machining, and quality control settings. It is also referenced when setting micrometers, verniers, and other measuring devices that require a known-diameter reference standard. At 0.2125 inches nominal diameter and 2.0 inches overall length, it fits comfortably in hand-held inspection routines on the shop floor or in a metrology lab.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface reduces friction and protects the hole being gauged
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards
• Compact 2.0-inch overall length for easy single-hand use

Compatibility

Designed for go inspection of holes with a nominal diameter of 0.2125 inches and for use as a setting reference with micrometers, verniers, and other measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power source or fasteners are required. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel. Never force the gage into a hole; if resistance is felt, the hole is undersized. Store with the accompanying Certificate of Accuracy to maintain traceability documentation for audits.
