Vermont Gage 112105220 Class Zz Plus Plug Gage 5.22 Mm

Product Description

The VERMONT GAGE 112105220 is a Class ZZ Plus cylindrical plug gage manufactured from tool steel for dimensional inspection of precision bores and holes. It measures 5.22 mm in diameter with a tolerance of 0.005 mm, making it suitable for go inspection applications where tight dimensional control is required. The gage features a 10 microfinish surface and ships with a Certificate of Accuracy traceable to NIST. Overall length is 2.0000 inches. Machinists, quality technicians, and metrology professionals use this tool to verify hole sizes against specification during incoming inspection, in-process checks, and final acceptance.

This plug gage is intended for go inspection use in precision manufacturing and quality control environments. It is compatible with standard gage handle systems and works alongside set micrometers, verniers, and other dimensional measuring devices. Typical applications include verifying drilled, reamed, or bored holes in machined components where ASME B89.1 dimensional standards must be met. It is well suited to both job shop and production floor inspection stations in industries such as aerospace, automotive, and general precision machining.

Key Features

• Class ZZ Plus tolerance grade - 0.005 mm tolerance for high-accuracy go inspection
• 10 microfinish surface for consistent, low-wear contact with inspected bores
• Tool steel construction for durability and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards
• Compact overall length of 2.0000 inches fits standard gage handles

Compatibility

Designed for use with standard cylindrical plug gage handle sets and compatible with set micrometers, verniers, and other measuring devices as noted in the product specifications. Suitable for any application requiring ASME B89.1 compliant go inspection of 5.22 mm diameter bores.

Installation Notes

Plug gages are handled and used by quality technicians and machinists - no power source or shutoff is required before use. Clean the gage and the bore being inspected before each use to prevent debris from affecting readings or damaging the gage surface. Store the gage in its protective case when not in use to preserve the 10 microfinish surface and dimensional integrity. Avoid dropping or stacking gages, as impact can alter calibration and invalidate NIST traceability.
