Vermont Gage 112322130 Class Zz Plus Plug Gage 22.13 Mm

Product Description

The VERMONT GAGE 112322130 is a Class ZZ Plus cylindrical plug gage designed for precision internal diameter inspection. It measures 22.13 mm in diameter with a tolerance of 0.00508 mm, making it suitable for Go inspection applications where tight dimensional verification is required. Constructed from tool steel with a 10 micro-inch coating and finish, this plug gage delivers the hardness and wear resistance expected in production and quality-control environments. It ships with a Certificate of Accuracy traceable to NIST, supporting documented inspection records. Overall length is 2.0000 inches. Licensed metrology technicians, quality engineers, and machining professionals are the primary users.

This plug gage is used in Go inspection routines to verify that a bored, reamed, or otherwise finished internal feature accepts a part within the specified dimensional tolerance. It is compatible with standard gage handle systems and is appropriate for use alongside set micrometers, verniers, and other precision measuring devices. Typical applications include incoming inspection, in-process quality checks, and final inspection on machined components in manufacturing facilities, job shops, and metrology labs.

Key Features

• Class ZZ Plus tolerance grade — 0.00508 mm tolerance for high-precision Go inspection
• Tool steel construction with 10 micro-inch coating for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST Traceability for documented quality records
• Conforms to ASME B89.1 standards for plain plug gages
• Compatible with standard gage handles and bench-top measuring instrument setups
• Overall length of 2.0000 inches suits most standard gage handle configurations

Compatibility

Designed for use in Go inspection applications alongside set micrometers, verniers, and other precision measuring devices where a 22.13 mm internal diameter reference is required.

Installation Notes

Plug gages are handled and used by quality technicians and metrology professionals following ASME B89.1 guidelines. Always store the gage in its protective case when not in use to prevent nicking or surface contamination. Clean mating bores and the gage surface with a lint-free cloth before gauging to avoid false readings caused by debris or coolant residue. Do not force the gage through a feature — excessive insertion force can damage the gage or the workpiece and invalidate the inspection result.
