Vermont Gage 112102640 Class Zz Plus Plug Gage 2.64mm

Product Description

The VERMONT GAGE 112102640 is a Class ZZ Plus cylindrical plug gage designed to verify bore diameters to a tolerance of 0.00508 mm. Machined from tool steel and finished to a 10 microfinish surface quality, this gage delivers the dimensional accuracy required for go-type inspection work. Every unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality-control environments where documentation is required. Metrology technicians, tool room machinists, and QC inspectors use this style of gage as a fast, reliable attribute check on machined bores, drilled holes, and precision-fit components.

This plug gage is intended for go inspection of 2.64 mm diameter bores and is compatible with standard gage handle systems used in production and inspection settings. It is also suited for use alongside set micrometers, verniers, and other calibrated measuring devices where a physical reference standard is needed. Typical applications include incoming inspection, in-process quality checks, and final verification of precision-machined parts in manufacturing, aerospace, automotive, and general toolroom environments.

Key Features

• Class ZZ Plus tolerance rating at 0.00508 mm for precise go-type attribute inspection
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for consistent, low-friction gage entry
• Includes Certificate of Accuracy with NIST traceability for documentation compliance
• Meets ASME B89.1 standards for plain cylindrical gages
• Overall length of 2.0 inches for standard gage handle compatibility

Compatibility

Designed for go inspection of 2.64 mm diameter bores. Compatible with set micrometers, verniers, and other precision measuring devices as a reference standard. Fits standard cylindrical plug gage handles appropriate for this diameter class.

Installation Notes

Plug gages of this type are handled and used by metrology technicians and quality-control personnel. No power source is required. Handle gages with clean, dry hands or cotton gloves to prevent corrosion from skin oils, and store in a protective case away from temperature extremes to maintain calibration integrity. Inspect the gage member for nicks or wear before each use, and recalibrate or replace if the surface shows signs of damage.
