Vermont Gage 111321850 Class Zz Plus Plug Gage 0.2185 in

Product Description

The VERMONT GAGE 111321850 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of holes and bores at 0.2185 inches diameter. It carries a tolerance of 0.0002 inches and a 10 microfinish surface on the gaging element, ensuring accurate, repeatable measurements in production and inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming compliance with ASME B89.1 standards. Dimensional inspection technicians, machinists, and quality control personnel use this gage as a reliable, traceable reference tool.

This plug gage is suited for go inspection operations in manufacturing and quality assurance settings, both in job shops and production facilities. It is used alongside set micrometers, verniers, and other precision measuring devices to verify bore diameter acceptance. The 2.0-inch overall length provides adequate handling clearance for bench inspection work. Its Class ZZ Plus classification targets inspection and calibration lab use where tighter tolerances on the gage itself are required beyond standard ZZ class.

Key Features

• Measures 0.2185 inches diameter with a tolerance of 0.0002 inches
• 10 microfinish surface on the gaging member for consistent, low-wear contact
• Constructed from tool steel for hardness and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional and tolerance standards
• 2.0 inches overall length for easy bench handling

Compatibility

Designed for use in go inspection applications and as a reference standard for setting micrometers, verniers, and other precision measuring devices, per the stated application data.

Installation Notes

Plug gages are handled and stored by dimensional inspection personnel and do not require mechanical installation. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Never force the gage into a bore; apply light, consistent hand pressure only. Store in the provided case or a controlled-environment gage cabinet to maintain dimensional integrity and NIST-traceable certification validity.
