Vermont Gage 112111840 Class Zz Plus Plug Gage 11.84mm

Product Description

The VERMONT GAGE 112111840 is a Class ZZ Plus cylindrical plug gage designed for go inspection of bored, reamed, or machined holes. It measures 11.84 mm in diameter with a tolerance of 0.00508 mm, and its 10 microfinish surface ensures accurate, repeatable contact with the work piece. The overall length is 2.0000 inches. Manufactured from tool steel, this gage delivers the hardness and wear resistance required for sustained use in production and inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements of most quality management systems. Dimensional metrology technicians, machinists, and quality control inspectors are the typical end users.

This plug gage is suited for go inspection tasks in machine shops, manufacturing cells, and metrology labs handling precision-toleranced components. It is also used to set and verify micrometers, verniers, and other measuring devices where a known-diameter reference is required. The 11.84 mm size fits into standard gage handle systems, making it a practical addition to any gage pin set covering the metric range.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for high-accuracy go inspection
• 10 microfinish surface for precise, low-distortion contact
• Tool steel construction for hardness and long service life
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• 2.0000-inch overall length compatible with standard plug gage handles

Compatibility

Designed as an OEM-style go inspection plug gage for use with standard gage handle systems in applications requiring a certified 11.84 mm reference diameter. Suitable for setting micrometers, verniers, and other measuring devices per the stated application data.

Installation Notes

Plug gages should be inserted and withdrawn with a smooth, axial motion - never forced or rocked, as this damages the gage and the work piece. Store the gage in its protective case when not in use to prevent surface damage to the lapped finish. Clean contact surfaces before use and allow the gage to reach ambient temperature when moving from cold storage to a temperature-controlled inspection area. Handling should comply with your facility's calibration control procedures and applicable ASME B89 guidelines.
