Vermont Gage 112317170 Class Zz Plus Plug Gage 17.17 Mm

Product Description

The VERMONT GAGE 112317170 is a Class ZZ Plus plug gage designed for precision bore and hole diameter inspection in metrology and quality control applications. Machined from tool steel with a 10 micro finish, this gage checks a nominal diameter of 17.17 mm with a tolerance of 0.00508 mm. It is used as a Go gage to verify that a hole or bore falls within the specified lower limit of tolerance. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and tool room personnel rely on this type of gage for fast, repeatable attribute inspection without the need for electronic measurement instruments.

This plug gage is suited for Go inspection tasks in manufacturing, machine shops, and quality labs. It is compatible with standard gage handle systems and used alongside micrometers, verniers, and other precision measuring devices for process verification. The 17.17 mm diameter and 2.0-inch overall length make it appropriate for inspecting drilled, reamed, or bored holes in production and toolroom environments. It is sized for single-piece or low-volume inspection setups and is a direct fit for any operation requiring ASME B89.1-class attribute gaging at this diameter.

Key Features

• 0.00508 mm tolerance for high-accuracy bore verification at 17.17 mm nominal diameter
• Includes Certificate of Accuracy with NIST traceability
• Overall length of 2.0 inches fits standard gage handle assemblies
• Compatible with micrometers, verniers, and other calibrated measuring setups

Compatibility

Designed for use in Go inspection applications with standard plug gage handles and compatible with micrometers, verniers, and other measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in controlled metrology environments. Store the gage in its protective case when not in use to prevent surface damage that could affect accuracy. Do not force the gage into a hole; light hand pressure is the correct technique for Go gaging. Clean and lightly oil the gage surface before and after use to prevent corrosion on the tool steel body.
