Vermont Gage 112305270 Class Zz Plus Plug Gage 5.27mm

Product Description

The VERMONT GAGE 112305270 is a Class ZZ Plus plug gage designed for precise internal diameter inspection. It features a 5.27 mm diameter with a tolerance of 0.005 mm, making it suitable for Go inspection applications where accurate dimensional verification is required. Manufactured from tool steel and finished to a 10 microfinish surface quality, this gage delivers consistent, repeatable measurements in shop-floor and quality-control environments. It ships with a Certificate of Accuracy with NIST Traceability, meeting ASME B89.1 standards. Metrology technicians, machinists, and quality inspectors rely on this type of plug gage for reliable go/no-go verification workflows.

This plug gage is used in manufacturing and inspection settings where tight bore tolerances must be verified. Typical applications include setting micrometers, verifying verniers, and calibrating other measuring devices. Its compact overall length of 2.0 inches makes it easy to handle during repetitive inspection tasks on production lines or in tool rooms. The Class ZZ Plus designation indicates it meets a defined tolerance grade appropriate for standard inspection use rather than master or reference-grade applications.

Key Features

• 5.27 mm inspection diameter with 0.005 mm tolerance for precise Go inspection
• Tool steel construction for durability and dimensional stability
• 10 microfinish surface for accurate, repeatable contact measurements
• Meets ASME B89.1 standards for dimensional gaging
• Includes Certificate of Accuracy with NIST Traceability
• Compact 2.0-inch overall length for easy handling in production environments

Compatibility

Suitable for use with micrometers, verniers, and other measuring devices requiring Go inspection verification; compatible with standard plug gage handles designed for this diameter class.

Installation Notes

Plug gages are handled and used by metrology technicians, machinists, and quality inspectors. Before use, ensure the gage and workpiece bore are clean and free of debris to prevent measurement error or surface damage. Do not force the gage through a bore; forcing can damage the gage or the workpiece and will produce invalid inspection results. Store in a protective case when not in use to maintain surface finish and dimensional integrity.
