Vermont Gage 111116900 Class Zz Plus Plug Gage 0.169 in

Product Description

The VERMONT GAGE 111116900 is a Class ZZ Plus plug gage used to verify bore and hole dimensions to tight tolerances in precision inspection work. Measuring 0.169 inches in diameter, this plug gage holds a tolerance of 0.0002 inches, making it suitable for go inspection applications where dimensional accuracy is critical. The gage is machined from tool steel and finished to a 10 microfinish surface quality. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming it meets ASME B89.1 standards. Metrology technicians, machinists, and quality control personnel use this type of instrument to validate part conformance on the shop floor or in an inspection lab.

This plug gage is designed for go inspection use, confirming that a hole or bore meets its minimum acceptable size. It is also suited for setting micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical applications include incoming inspection, in-process quality checks, and calibration of measuring instruments in both production and tool-and-die environments. The compact 2.0-inch overall length makes it easy to handle during repetitive inspection tasks.

Key Features

• 10 microfinish surface for consistent, reliable contact with measured surfaces
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional standard
• Compact 2.0-inch overall length for easy single-hand operation

Compatibility

Designed for go inspection of features at 0.169 inches diameter and for use as a reference standard when setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Handle plug gages with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Store the gage in its protective case when not in use to preserve the finished surface and dimensional integrity. Before use, verify the gage surface is free of burrs, debris, or oil that could affect measurement accuracy. Recalibrate or re-verify traceability at intervals consistent with your facility quality plan and applicable metrology standards.
