Vermont Gage 111193800 Class Zz Plus Plug Gage 0.938 in

Product Description

The VERMONT GAGE 111193800 is a Class ZZ Plus plug gage designed for precise go inspection of bored, drilled, and reamed holes with a nominal diameter of 0.938 inches. Manufactured from tool steel with a 10 microfinish surface finish, this gage delivers a diameter tolerance of 0.0002 inches, meeting the requirements of ASME B89.1. At 2.0 inches in overall length, it is a compact, single-ended inspection tool suited for quality control checks on the shop floor or in a calibration lab. Each unit ships with a Certificate of Accuracy carrying NIST traceability, making it ready for use in documented inspection programs.

This plug gage is used to verify that a hole meets its minimum acceptable size before a mating part is assembled. It is appropriate for inspecting machined components in production environments, toolrooms, and job shops. Typical applications include go inspection checks performed with set micrometers, verniers, and other measuring devices where a traceable reference standard is required. The tight Class ZZ Plus tolerance makes it suitable for applications where standard Class ZZ gages do not provide sufficient accuracy.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• 10 microfinish surface on the gage member for consistent, low-wear contact
• Tool steel construction for durability in shop and lab environments
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for documented QC programs
• Compact 2.0-inch overall length for easy handling and storage

Compatibility

Designed for use as a go inspection reference with set micrometers, verniers, and other measuring devices requiring a traceable plug gage standard at 0.938 inches nominal diameter.

Installation Notes

Plug gages should be handled by metrology or quality control personnel following standard gage-handling procedures. Clean the gage and the part bore before each measurement to prevent debris from causing false readings or surface damage. Store the gage in its protective case when not in use to preserve the finish and calibration integrity. Do not force the gage into an undersized hole, as this can damage both the gage member and the workpiece.
