Vermont Gage 111162700 Class Zz Plus Plug Gage 0.627 in

Product Description

The VERMONT GAGE 111162700 is a Class ZZ Plus plug gage designed for go inspection of bored, drilled, and reamed holes. It measures a nominal diameter of 0.627 inches with a tolerance of 0.0002 inches, making it suitable for precision dimensional verification in manufacturing and quality control environments. The gage features a 10 microinch surface finish on the measuring member, ensuring consistent contact and repeatable readings. Tool steel construction provides the wear resistance and dimensional stability required for regular use in production and inspection settings. A Certificate of Accuracy with NIST traceability is included, supporting compliance with documented quality programs.

This plug gage is used in applications requiring go-side verification of hole diameter on machined components. It is appropriate for use alongside set micrometers, verniers, and other calibrated measuring devices. The 0.627-inch diameter range targets common machined features in light industrial and precision manufacturing contexts. At 2.0 inches overall length, the gage handle provides adequate grip for manual inspection operations. Manufactured to ASME B89.1 standards, this gage is suited for both in-process checks on the shop floor and final inspection in a quality lab.

Compatibility

Designed for go inspection of holes measuring 0.627 inches in diameter, compatible with standard plug gage handles and used alongside set micrometers, verniers, and other measuring devices as specified in the product application data.

Installation Notes

Plug gages are installed and used by quality technicians, machinists, and metrology personnel. Before use, clean the gage member and the hole being inspected to remove chips, oil, and debris that could affect measurement accuracy. Apply only the hand force necessary to check for go-side passage; do not force the gage into an undersized hole. Store the gage in its case away from heat sources and other tools to prevent damage to the precision-ground surface.
