Vermont Gage 911301150 Class Zz Plus Plug Gage 0.0115 in

Product Description

The VERMONT GAGE 911301150 is a Class ZZ Plus plug gage designed for precise go inspection of small bores and holes at 0.0115 inches diameter. Manufactured from tool steel with a black oxide finish, this gage delivers a tolerance of 0.0002 inches, making it suitable for high-accuracy dimensional verification. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming conformance to ASME B89.1 standards. Machinists, quality control technicians, and metrology professionals rely on plug gages of this type to verify that a feature meets the minimum acceptable size before components move to assembly.

This plug gage is used in precision metrology and quality inspection applications across manufacturing, machining, and tool-and-die environments. It is suitable for go inspection work and can be used alongside set micrometers, verniers, and other measuring devices to establish or verify calibration references. The 2.0-inch overall length provides adequate handling clearance when checking tight-tolerance bores at the bench or on the shop floor.

Key Features

• Class ZZ Plus tolerance grade at 0.0002 inches for high-precision go inspection
• Tool steel construction for durability and dimensional stability
• Black oxide finish resists corrosion and reduces surface glare during inspection
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standard
• Compact 2.0-inch overall length suited for bench and in-process inspection

Compatibility

Designed for go inspection use with set micrometers, verniers, and other measuring devices requiring a 0.0115-inch diameter reference standard per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power source or utility shutoff is required. Store the gage in its protective case when not in use and avoid contact with abrasive surfaces that could alter the lapped finish. Clean the gage and the bore being checked before use to prevent debris from affecting the measurement result. Do not force the gage into an undersized feature, as this can damage the lapped surface and compromise accuracy.
