Vermont Gage 911306350 Class Zz Plus Plug Gage 0.0635 in

Product Description

The VERMONT GAGE 911306350 is a Class ZZ Plus plug gage designed for precision go inspection of bored holes and machined features with a nominal diameter of 0.0635 inches. Built from tool steel with a black oxide finish, this gage delivers a tolerance of 0.0002 inches, meeting the dimensional verification requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy bearing NIST traceability, making it suitable for use in calibrated inspection environments. Machinists, quality technicians, and metrology professionals use this gage to confirm that a workpiece opening meets minimum acceptable size for assembly or function.

This plug gage is used in dimensional inspection applications including go-type verification of small-diameter holes in manufactured parts. It is compatible with use alongside set micrometers, verniers, and other precision measuring devices where a reference standard is needed. Typical install scenarios include incoming inspection, in-process quality checks, and final inspection on the shop floor or in a metrology lab. The compact 2.0-inch overall length makes it easy to handle and store in standard gage blocks or tooling trays.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go inspection
• 0.0635-inch measurement diameter for small-bore verification
• Tool steel construction for durability and dimensional stability
• Black oxide finish provides corrosion resistance and reduces glare during inspection
• Includes Certificate of Accuracy with NIST traceability for calibrated inspection use
• Meets ASME B89.1 dimensional gage standards

Compatibility

Designed for use as a go plug gage in conjunction with set micrometers, verniers, and other precision measuring devices requiring a traceable dimensional reference at 0.0635 inches diameter.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists in inspection environments rather than installed in a mechanical system. Keep the gage clean and lightly oiled when not in use to prevent corrosion and maintain dimensional accuracy. Do not force the gage into an undersized hole, as this can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to preserve NIST-traceable calibration.
