Vermont Gage 112119280 Class Zz Plus Plug Gage 19.28mm

Product Description

The VERMONT GAGE 112119280 is a Class ZZ Plus plug gage designed for go inspection of bored, drilled, and reamed holes. Manufactured from tool steel with a 10 micro finish, it checks whether a hole falls within the accepted tolerance range for its nominal diameter. The 112119280 measures 19.28 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for precision inspection workflows. Every unit ships with a Certificate of Accuracy that carries NIST traceability, supporting ISO and quality-system documentation requirements. Machinists, quality technicians, and tool room inspectors are the primary users of this gage.

This plug gage is used in machine shops, manufacturing cells, and inspection departments for go-type attribute gaging on holes nominally sized at 19.28 mm. It is well suited for verifying parts prior to assembly, auditing CNC output, and setting or confirming the calibration of micrometers, verniers, and other measuring devices. The overall length of 2.0000 inches makes it compact enough for bench use or integration into a standard gage handle. Typical applications include production inspection of metal components where hole size conformance to ASME B89.1 is required.

Key Features

• Class ZZ Plus tolerance grade: 0.00508 mm, suitable for go inspection on precision bored or reamed holes
• Tool steel construction with 10 micro surface finish for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for quality-system compliance
• Conforms to ASME B89.1 dimensional gage standards
• Compact 2.0000-inch overall length compatible with standard gage handles
• Can be used to set or verify micrometers, verniers, and comparable measuring instruments

Compatibility

Designed as an OEM-style go plug gage for attribute inspection of holes at a nominal diameter of 19.28 mm. Suitable for use with standard gage handles and holders sized for the corresponding diameter class.

Installation Notes

Plug gages are handled and used by quality technicians or machinists and do not require permanent installation. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Never force a go gage through a hole; if it does not pass under hand pressure, the hole is undersized. Store in the provided case or a padded gage tray to protect the lapped surface from contact damage that could affect dimensional accuracy.
