Vermont Gage 111136300 Class Zz Plus Plug Gage 0.363 in

Product Description

The VERMONT GAGE 111136300 is a Class ZZ Plus plug gage used to verify that a drilled, reamed, or machined hole meets its minimum acceptable diameter. The gage measures a nominal diameter of 0.363 inches with a tolerance of 0.0002 inches and features a 10 microfinish surface on the gaging member. It is manufactured from tool steel for durability and dimensional stability under repeated use. At 2.0 inches overall length, it handles easily in standard bench or in-process inspection settings. A Certificate of Accuracy with NIST traceability is included, confirming the gage has been verified against national measurement standards before shipment.

This plug gage is intended for Go inspection of holes at the 0.363-inch nominal size. It is used alongside micrometers, verniers, and other measuring devices as part of a complete dimensional inspection routine. Typical applications include incoming inspection, in-process quality control, and final acceptance checks in machine shops, tool rooms, and light manufacturing environments. It is suited for both production floor use and metrology lab settings where Class ZZ tolerances are required.

Key Features

• Class ZZ Plus tolerance class for Go inspection of 0.363-inch diameter holes
• 0.0002-inch tolerance for reliable pass/fail dimensional verification
• 10 microfinish surface for consistent contact and reduced wear on the hole being checked
• Tool steel construction provides hardness and long service life
• Meets ASME B89.1 standards for plain plug gages
• Includes Certificate of Accuracy with NIST traceability

Compatibility

Designed for use in Go inspection of holes with a nominal diameter of 0.363 inches. Compatible for use with standard setting micrometers, verniers, and other measuring devices as noted in the application data.

Installation Notes

Plug gages are handled and applied by quality technicians, machinists, or metrologists. Before use, clean both the gage and the workpiece hole with a lint-free cloth to remove chips, oil, or debris that could cause false readings or damage the gage surface. Never force a plug gage into a hole; controlled hand pressure is sufficient for a Go gage check. Store the gage in its protective case when not in use to prevent corrosion and surface damage to the precision-ground member.
