Vermont Gage 111189600 Class Zz Plus Plug Gage 0.896 in

Product Description

The VERMONT GAGE 111189600 is a Class ZZ Plus plug gage designed for precise bore and hole diameter inspection in machine shops, toolrooms, and manufacturing environments. Measuring a nominal diameter of 0.896 inches with a tolerance of 0.0002 inches, this gage delivers the dimensional accuracy required for Go inspection applications. The 10 microinch surface finish on the measuring surfaces ensures consistent, repeatable contact. It is constructed from tool steel for durability under regular production use and comes with a Certificate of Accuracy traceable to NIST standards. Machinists, quality control inspectors, and toolroom technicians are the primary users of this instrument.

This plug gage is suited for Go inspection of bored holes, drilled passages, and machined features requiring tight dimensional control at the 0.896-inch nominal size. It is compatible with standard gage handle systems and is appropriate for use alongside set micrometers, verniers, and other precision measuring devices as referenced in its application data. Both production floor inspection and incoming quality inspection are typical use scenarios. The overall length of 2.0 inches allows for straightforward use in a handheld or bench-mounted setup.

Compatibility

Designed for Go inspection use with standard plug gage handle systems and compatible with set micrometers, verniers, and other measuring devices as specified by the manufacturer.

Installation Notes

Plug gages are installed and used by machinists, toolroom technicians, and quality control inspectors. Before use, clean both the gage and the workpiece bore to remove debris, oil, or chips that could affect measurement accuracy. Apply light gage oil if required by your shop practice to protect the tool steel surfaces. Store the gage in its protective case when not in use and handle it carefully to avoid surface damage that could affect dimensional accuracy.
