Vermont Gage 111159200 Class Zz Plus Plug Gage 0.592 in

Product Description

The VERMONT GAGE 111159200 is a Class ZZ Plus plug gage designed for precise dimensional inspection of bored holes, machined features, and other internal diameters. It measures a nominal diameter of 0.592 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish, making it suitable for high-accuracy go inspection work. Manufactured from tool steel for durability and dimensional stability, this gage ships with a Certificate of Accuracy that carries full NIST traceability. It is used by quality control technicians, machinists, and metrologists who require reliable, standards-compliant inspection tooling on the shop floor or in the metrology lab.

This plug gage is applied in go inspection routines to verify that a hole or bore meets minimum size requirements. It is also used as a reference standard for setting micrometers, verniers, and other measuring devices to a known diameter. With an overall length of 2 inches, it is sized for easy single-hand operation in typical production or inspection environments. Facilities operating under ASME B89.1 dimensional standards will find this gage a direct fit for their quality management programs.

Key Features

• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Compact 2-inch overall length for convenient handling

Compatibility

Designed for use in go inspection of internal diameters and for setting micrometers, verniers, and other measuring devices requiring a 0.592-inch reference standard.

Installation Notes

Plug gages are handled and applied by quality control technicians and machinists following standard metrology practices. Store the gage in its protective case when not in use and keep it free of contaminants, oils, and debris that can affect measurement accuracy. Allow the gage and workpiece to reach the same ambient temperature before use, as thermal expansion can introduce measurement error. Calibration intervals should follow facility quality management procedures and applicable ASME standards.
