Vermont Gage 112306210 Class Zz Plus Plug Gage 6.21 Mm

Product Description

The VERMONT GAGE 112306210 is a Class ZZ Plus plug gage designed to verify bore and hole diameters in precision inspection applications. Manufactured from tool steel with a 10 microfinish surface, this gage checks a nominal diameter of 6.21 mm with a tolerance of 0.00508 mm, providing reliable Go inspection accuracy. It meets ASME B89.1 dimensional standards and ships with a Certificate of Accuracy traceable to NIST. Metrology technicians, machinists, and quality control inspectors use this gage for incoming and in-process inspection work.

This plug gage is suited for Go inspection checks on bored holes, drilled features, and precision-machined diameters measuring 6.21 mm. It is also used to set and verify micrometers, verniers, and other measuring devices in tool rooms and inspection departments. The compact overall length of 2.0000 inches makes it easy to handle during bench inspection routines in both production and job-shop environments.

Key Features

• Class ZZ Plus tolerance class - 0.00508 mm tolerance for dependable Go inspection results
• 10 microfinish surface for consistent, low-wear contact with inspected bores
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documented calibration records
• Tool steel construction for hardness and long service life in production inspection settings
• Overall length of 2.0000 inches - compact form for bench and hand-held use

Compatibility

Designed as an OEM-style Go plug gage for use with standard gage handles and holders sized for 6.21 mm inspection members. Also compatible for setting and verifying micrometers, verniers, and other calibrated measuring devices as noted in supplier specifications.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and dimensional contamination. Store the gage in its protective case when not in use and allow it to reach ambient temperature before use, as thermal expansion can affect readings at this tolerance class. Do not force the gage into a feature - if resistance is felt during Go inspection, stop and investigate the bore condition. Calibration and recertification intervals should follow your facility quality plan and applicable metrology standards.
