Vermont Gage 112305530 Class Zz Plus Plug Gage 5.53mm

Product Description

The VERMONT GAGE 112305530 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore diameter accuracy in precision inspection applications. Measuring 5.53 mm in diameter with a tolerance of 0.00508 mm, this gage is built for go inspection work where tight dimensional control is required. The tool steel construction combined with a 10 microfinish surface coating ensures consistent, repeatable contact with the workpiece. At 2.0 inches in overall length, it is compact enough for bench inspection and compatible with standard gage handle systems. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards.

This plug gage is suited for quality control technicians, machinists, and metrology professionals working in manufacturing environments where bore tolerances must be verified to tight specifications. It is used with go inspection setups to confirm that a bore falls within the acceptable size range. The gage is also compatible with setting micrometers, verniers, and other measuring devices where a known reference diameter is needed. Typical applications include incoming inspection, in-process quality checks, and final part verification on machined components.

Key Features

• Class ZZ Plus tolerance class: 0.00508 mm tolerance for precision go inspection
• Tool steel construction for durability and wear resistance in repeated use
• 10 microfinish surface coating for accurate, consistent gage contact
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 standards for plain plug gages
• Compatible with setting micrometers, verniers, and other measuring devices

Compatibility

Suitable for use in go inspection setups and compatible with setting micrometers, verniers, and other measuring devices per the manufacturer application data. Designed as a replacement or supplemental gage for any standard gage handle system accepting 5.53 mm diameter plug gage members.

Installation Notes

This gage is handled by quality control technicians and metrologists and requires no power or mechanical installation. Clean the gage and bore surface before use to prevent contamination from affecting readings. Store the gage in its case when not in use to protect the precision ground surface from damage. Follow ASME B89.1 guidelines for proper handling, calibration intervals, and storage of plug gages.
