Vermont Gage 112316670 Class Zz Plus Plug Gage 16.67mm

Product Description

The VERMONT GAGE 112316670 is a Class ZZ Plus cylindrical plug gage manufactured from tool steel, designed for dimensional inspection of bored holes and machined features. With a nominal diameter of 16.67 mm and a tolerance of 0.00508 mm, this gage provides the close-tolerance accuracy required for Go inspection work. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming dimensional compliance at the point of use. This gage is installed and used by quality control technicians, machinists, and metrology professionals performing in-process or final part inspection.

The 112316670 is suited for Go inspection applications in manufacturing, machine shops, and quality assurance environments. It is compatible with use alongside set micrometers, verniers, and other precision measuring devices as referenced in its application rating. The gage conforms to ASME B89.1, the governing standard for dimensional measurement tools in industrial metrology. A 10 Micro coating finish on the gage surface supports consistent, repeatable contact with the bore surface during inspection routines.

Compatibility

Designed for Go inspection use with set micrometers, verniers, and other precision measuring devices. Suitable for inspection of 16.67 mm nominal diameter bored holes and machined features in standard manufacturing and quality control applications.

Installation Notes

Plug gages are handled and applied by quality technicians and machinists; no power shutoff is required, but the workpiece must be free of chips, coolant, and debris before gaging. Store the gage in its case when not in use to prevent damage to the precision ground surface. Do not force the gage into a bore — proper Go gage practice relies on gravity or light hand pressure only. Handle with clean gloves or a gage cloth to prevent thermal expansion from hand contact affecting measurement accuracy.
