Vermont Gage 111169800 Class Zz Plus Plug Gage 0.698 in

Product Description

The VERMONT GAGE 111169800 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes and machined features. Manufactured from tool steel, this gage measures a nominal diameter of 0.698 inches with a tight tolerance of 0.0002 inches. The working surface carries a 10 microfinish, ensuring accurate, repeatable contact during go inspection routines. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. This gage is used by quality technicians, machinists, and metrology professionals who require reliable attribute inspection tooling on the shop floor or in a gauge room.

This plug gage is suited for go inspection applications on precision-machined components where hole diameter conformance must be verified. It is also commonly used to set and calibrate micrometers, verniers, and other measuring devices requiring a known reference standard at the 0.698-inch diameter. Typical deployment spans manufacturing, tooling, and quality-control environments in both production and inspection settings where ASME B89.1 compliance is required.

Key Features

• Nominal measurement diameter of 0.698 inches for precise hole gauging
• Class ZZ Plus tolerance of 0.0002 inches for tight attribute inspection
• 10 microfinish surface for consistent, low-wear contact
• Tool steel construction for durability under repeated use
• NIST-traceable Certificate of Accuracy included with each unit
• Conforms to ASME B89.1 dimensional standards

Compatibility

Designed for go inspection of machined holes and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 0.698-inch diameter reference.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source is required. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion of the tool steel. Do not force the gage into an undersize hole, as this will damage the gage and compromise its calibration. Store in its protective case away from impact, temperature extremes, and abrasive contaminants to maintain NIST-traceable accuracy.
