Vermont Gage 111141400 Class Zz Plus Plug Gage 0.414 in

Product Description

The VERMONT GAGE 111141400 is a Class ZZ Plus plug gage designed for dimensional inspection of bores, holes, and internal features measuring 0.414 inches in diameter. Built from tool steel, it holds a tolerance of 0.0002 inches and features a 10 microfinish surface on the gaging member. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. This gage is used by quality control technicians, machinists, and metrology professionals to verify that machined or drilled features fall within specified dimensional tolerances.

This plug gage is suited for go inspection applications in manufacturing, machine shop, and quality assurance environments. It is also used to calibrate and verify the accuracy of setting micrometers, verniers, and other precision measuring devices. The 0.414-inch diameter and 2.0-inch overall length make it practical for bench inspection work and in-process checks on production floors where tight tolerance control is required.

Key Features

• Class ZZ Plus tolerance rating with 0.0002-inch tolerance for precise go inspection
• 10 microfinish surface on the gaging member for consistent, repeatable contact
• Tool steel construction for durability and dimensional stability
• Meets ASME B89.1 standards for gage accuracy and performance
• Includes Certificate of Accuracy with NIST traceability
• 2.0-inch overall length suits standard bench and in-process inspection setups

Compatibility

Designed for go inspection of bores and holes at 0.414 inches diameter; also used as a setting reference for micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and stored by metrology or quality control personnel following standard gage handling procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Avoid dropping or contacting the gaging member against hard surfaces, as impact can alter dimensional accuracy. Periodic recalibration against NIST-traceable standards is recommended to maintain measurement integrity.
