Vermont Gage 111114900 Class Zz Plus Plug Gage 0.149 in

Product Description

The VERMONT GAGE 111114900 is a Class ZZ Plus plug gage designed to measure bore and hole diameters to a nominal 0.149 inches. Manufactured from tool steel and finished to a 10 microfinish surface, it delivers tight dimensional control with a tolerance of 0.0002 inches. The gage has an overall length of 2.0 inches and is supplied with a Certificate of Accuracy traceable to NIST, meeting the requirements of ASME B89.1. It is used primarily as a Go inspection member to confirm that a hole or bore is within the specified minimum size limit.

This plug gage is suited for incoming inspection, in-process quality control, and final acceptance checking in machine shops, toolrooms, and manufacturing environments. It is used with set micrometers, verniers, and other precision measuring devices to verify bore dimensions in ferrous and non-ferrous workpieces. The compact 2.0-inch overall length makes it easy to handle in bench inspection and floor-level quality stations alike.

• Tool steel construction provides long service life in production environments
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• 2.0-inch overall length for easy single-hand handling at inspection stations

Compatibility

Designed for use as a Go inspection gage for holes and bores with a nominal diameter of 0.149 inches. Compatible for use alongside set micrometers, verniers, and other precision measuring devices as stated in the product application data.

Installation Notes

Plug gages are handled and applied by quality technicians, machinists, and toolroom personnel — not installed in a permanent sense. Before use, clean both the gage and the workpiece bore to remove chips, coolant, and debris that can affect the reading. Never force a plug gage into a bore; if the Go member does not enter with light hand pressure, stop and assess the bore condition. Store the gage in a protective case away from other tools to preserve the precision ground surface and prevent corrosion.
