Vermont Gage 111191700 Class Zz Plus Plug Gage 0.917 in

Product Description

The VERMONT GAGE 111191700 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection work. It measures a nominal diameter of 0.917 inches with a tolerance of 0.0002 inches and a surface finish of 10 microinches. This type of gage is used to verify that a drilled, reamed, or bored hole meets minimum acceptable size before a part advances in production. The part ships with a Certificate of Accuracy backed by NIST traceability, satisfying quality documentation requirements on the shop floor or in a metrology lab. Machinists, quality technicians, and inspection personnel are the primary users.

Class ZZ Plus plug gages are suited for production inspection environments where cost-effective go-type checking is required. This gage is appropriate for calibrating or verifying the setup of set micrometers, verniers, and other measuring devices, as stated by the manufacturer. It fits into standard gage handle holders sized for the 0.917-inch nominal range. Typical applications include incoming inspection, in-process quality checks, and first-article verification in machine shops, manufacturing facilities, and quality control departments.

Key Features

• Nominal measurement diameter of 0.917 inches with 0.0002-inch tolerance for precise go inspection
• Tool steel construction for hardness and wear resistance in repetitive inspection use
• 10-microinch surface finish for consistent, accurate contact with the workpiece bore
• Includes Certificate of Accuracy with NIST traceability to support quality management documentation
• Conforms to ASME B89.1 standards for plain gages
• Overall length of 2.0 inches for easy handling with standard gage handle accessories

Compatibility

Designed for use in standard plug gage handles sized for the 0.917-inch diameter range. Also suitable as a reference standard for setting set micrometers, verniers, and other measuring devices per manufacturer application data.

Installation Notes

Plug gages are handled and stored by quality technicians and machinists following shop metrology procedures. Always clean the gage and the bore being checked before use to prevent false readings or gage wear. Store the gage in its protective case away from cutting fluids, chips, and temperature extremes that could affect calibration. Periodic recalibration intervals should follow your facility quality plan and any applicable ISO or ASME B89 requirements.
