Vermont Gage 112102460 Class Zz Plus Plug Gage 2.46mm

Product Description

The VERMONT GAGE 112102460 is a Class ZZ Plus cylindrical plug gage machined from tool steel for use in precision dimensional inspection. It checks a 2.46 mm diameter bore to a tolerance of 0.00508 mm and carries a 10 microfinish surface rating on the gaging surface. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for quality systems operating under ASME B89.1 standards. Machinists, tool-room technicians, and quality control inspectors use this gage to verify hole size conformance in production and inspection environments.

This plug gage is suited for go inspection of small-diameter bores in both production and metrology settings. It is also used to calibrate and verify the accuracy of micrometers, verniers, and other measuring devices where a certified reference standard is required. The small diameter makes it appropriate for precision work in tight bore applications common in aerospace, medical device, and general machining environments. Single-unit packaging supports tool-crib management and individual inspection station use.

Key Features

• Class ZZ Plus tolerance grade at 0.00508 mm for high-accuracy go inspection
• 10 microfinish gaging surface minimizes wear and ensures consistent contact
• Tool steel construction provides hardness and dimensional stability
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed as an OEM-style precision reference standard for go inspection of 2.46 mm diameter bores, and for setting or verifying micrometers, verniers, and comparable measuring instruments.

Installation Notes

Plug gages should be handled by quality control technicians or machinists following standard metrology practices. Store the gage in its protective case when not in use to prevent surface damage or corrosion. Clean the gaging surface with a lint-free cloth and appropriate solvent before use. Never force the gage into a bore; if resistance is encountered, the bore is undersized and should be evaluated before proceeding.
