Vermont Gage 111143600 Class Zz Plus Plug Gage 0.436 in

Product Description

The VERMONT GAGE 111143600 is a Class ZZ Plus plug gage designed for precision dimensional inspection. With a nominal measurement diameter of 0.436 inches and a tolerance of 0.0002 inches, this gage delivers the accuracy required for Go inspection tasks in quality control and calibration environments. Constructed from tool steel with a 10 microfinish surface, it provides consistent, repeatable results across high-use inspection workflows. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Licensed metrology technicians, machinists, and quality assurance professionals are the primary users of this tool.

This plug gage is suited for Go inspection of bored holes, drilled passages, and machined features in both production and inspection settings. It is also used to verify and set micrometers, verniers, and other precision measuring devices. The 2.0-inch overall length makes it practical for bench use and handheld inspection tasks in manufacturing, tool rooms, and metrology labs handling tight-tolerance work at the 0.436-inch diameter range.

Key Features

• 0.436-inch measurement diameter for precise Go inspection at that nominal size
• 0.0002-inch tolerance meets Class ZZ Plus accuracy requirements per ASME B89.1
• 10 microfinish surface finish minimizes wear and ensures consistent gage contact
• Tool steel construction provides durability in production inspection environments
• Includes Certificate of Accuracy with NIST traceability for documentation and audit compliance
• 2.0-inch overall length suits bench and handheld inspection applications

Compatibility

Designed for Go inspection use and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a 0.436-inch diameter reference.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Store in a protective case away from temperature extremes and direct contact with other metal tooling to preserve the surface finish and dimensional integrity. Verify the gage against the Certificate of Accuracy documentation before placing it into a calibration or inspection routine. Gage maintenance and periodic recertification should follow your facility quality management procedures and applicable ASME B89.1 guidelines.
