Vermont Gage 112315430 Class Zz Plus Plug Gage 15.43mm

Product Description

The VERMONT GAGE 112315430 is a Class ZZ Plus plug gage designed for go-type dimensional inspection of bored, drilled, and reamed holes. It checks whether a hole falls within the acceptable size range before parts move to the next stage of production or assembly. The gage is machined from tool steel and finished to a 10 micro surface finish for repeatable contact. At 15.43 mm nominal diameter with a tolerance of 0.00508 mm (0.005 mm), it meets the dimensional requirements of ASME B89.1 and ships with a Certificate of Accuracy traceable to NIST.

This plug gage is suited for quality control and inspection work in machine shops, manufacturing facilities, and precision assembly environments. It is used with go inspection routines and complements set micrometers, verniers, and other calibrated measuring devices. The overall length of 2.0000 inches makes it compatible with standard handle sets. It is typically handled by machinists, quality technicians, and metrology lab personnel performing in-process or final inspection checks on workpieces requiring tight hole-diameter control.

Key Features

Compatibility

Designed as an OEM-style go plug gage for use with standard plug gage handle sets in dimensional inspection applications requiring ASME B89.1 compliance.

Installation Notes

Plug gages are installed and used by machinists and quality control technicians. Before use, clean both the gage and the workpiece bore with a lint-free cloth to remove chips, oil, and debris that could affect readings. Never force the gage into a bore; apply only light, consistent hand pressure to avoid wear or damage to the gage surface. Store the gage in its protective case when not in use to prevent nicking the ground surface.
