Vermont Gage 112106840 Class Zz Plus Plug Gage 6.84 Mm

Product Description

The VERMONT GAGE 112106840 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore and hole diameters to tight dimensional tolerances. It carries a 0.005 mm tolerance and a 10 microfinish surface finish, making it suitable for precision go inspection work where consistent, repeatable measurement is required. The overall length is 2.0000 inches and the gage weighs 0.04 pounds. Each unit ships with a Certificate of Accuracy with NIST traceability, supporting quality documentation requirements in manufacturing and metrology environments. Licensed metrologists, machinists, and quality control technicians are the primary users.

This plug gage is used in go inspection applications to confirm that a hole or bore has been machined within the specified minimum acceptable diameter. It is also suitable for setting micrometers, verniers, and other measuring devices where a known reference diameter is needed. The 6.84 mm nominal diameter covers a common range of precision bore work encountered in general machining, toolroom, and production inspection settings. Conforms to ASME B89.1 standards.

Key Features

• Class ZZ Plus tolerance class with 0.005 mm tolerance for tight dimensional control
• 10 microfinish surface finish minimizes wear on the gage and the workpiece bore
• Tool steel construction provides hardness and wear resistance for production use
• Includes Certificate of Accuracy with NIST traceability for calibration records
• Conforms to ASME B89.1 dimensional gage standards
• Overall length of 2.0000 inches suits standard gage handle and pin-gage holder setups

Compatibility

Designed as an OEM-style precision reference gage for use with standard plug gage handles and pin-gage holders in go inspection, micrometer setting, and vernier calibration applications.

Installation Notes

Plug gages are installed and used by machinists, metrologists, and quality technicians - no special tools are required beyond a compatible gage handle. Clean the gage and the bore with a lint-free cloth before use to prevent contamination from affecting measurement accuracy. Do not force the gage into the bore; a go gage should pass through a conforming hole under its own weight or with minimal hand pressure. Store the gage in its case when not in use to protect the finished surface and preserve traceability documentation.
