Vermont Gage 112119080 Class Zz Plus Plug Gage 19.08mm

Product Description

The VERMONT GAGE 112119080 is a Class ZZ Plus plug gage designed for go inspection of bored, reamed, and machined holes at a nominal diameter of 19.08 mm. Manufactured from tool steel with a 10 micro finish, this gage provides a tolerance of 0.00508 mm, meeting the requirements of ASME B89.1. Each unit ships with a Certificate of Accuracy with NIST traceability, giving quality technicians and machinists documented evidence of calibration. The overall length is 2.0000 inches, making it compact and easy to handle on the shop floor or in a quality lab setting. Metrology professionals, toolroom machinists, and quality control inspectors use this gage for fast, reliable attribute inspection of hole diameters.

This plug gage is suited for use in production and quality control environments where hole diameter conformance must be verified quickly and accurately. It is used alongside set micrometers, verniers, and other precision measuring devices to support go inspection workflows. The 19.08 mm diameter targets holes produced by drilling, reaming, or boring operations in both light manufacturing and precision machining applications. This is a single-end go gage, appropriate for residential shop use, tool and die environments, and production floor inspection stations.

Key Features

• Tool steel construction with a 10 micro finish for durability and wear resistance
• Includes Certificate of Accuracy with NIST traceability for documentation and calibration records
• Overall length of 2.0000 inches for easy single-hand use
• Compatible with go inspection setups alongside micrometers, verniers, and comparable measuring devices

Compatibility

Designed for go inspection use with set micrometers, verniers, and other precision measuring devices where 19.08 mm hole diameter verification is required.

Installation Notes

Plug gages are handled and used by quality control technicians and toolroom machinists. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Never force the gage into a hole; go gages should pass under their own weight or with minimal hand pressure. Store in a protective case away from abrasive materials to maintain tolerance integrity.
