Vermont Gage 112317650 Class Zz Plus Plug Gage 17.65mm

Product Description

The VERMONT GAGE 112317650 is a Class ZZ Plus plug gage machined from tool steel for dimensional go inspection of bored holes, machined features, and precision-fit openings. The gage checks a nominal diameter of 17.65 mm with a tolerance of 0.005 mm, making it suitable for quality-control and incoming-inspection workflows. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting the documentation requirements common in ISO and AS9100 shop environments. A 10 micro-inch coating finish protects the gaging surface and extends service life. Machinists, quality technicians, and tool-and-die professionals use this gage as a fast, reliable attribute-inspection tool at the machine or inspection bench.

This plug gage is designed for go inspection of 17.65 mm diameter features in production and job-shop settings. It works alongside set micrometers, vernier calipers, and other precision measuring devices as a quick pass-fail reference. Typical applications include checking drilled, reamed, or honed holes in metal and engineered-plastic workpieces where tight dimensional tolerances must be verified before assembly. The gage is equally at home on a receiving-inspection table or mounted in a dedicated gage stand at the point of manufacture. It is sized for single-operator handheld use and requires no special fixture for routine inspection tasks.

Key Features

• Class ZZ Plus accuracy with 0.005 mm tolerance for reliable go inspection
• Tool steel construction for wear resistance in high-cycle inspection environments
• 10 micro-inch coating finish protects the gaging surface from corrosion and wear
• Includes Certificate of Accuracy with NIST traceability for documentation and audit compliance
• Conforms to ASME B89.1 standards for plain plug gages
• Compact 2.0000-inch overall length for handheld use

Compatibility

Designed for go inspection use with set micrometers, verniers, and other precision measuring devices requiring a 17.65 mm diameter reference standard.

Installation Notes

Plug gages are used by quality technicians and machinists and require no permanent installation. Before use, clean both the gage and the workpiece bore with a lint-free cloth to remove chips, coolant, and debris that could affect the reading. Never force the gage through a bore; if resistance is felt beyond normal hand pressure, the feature is undersize and the gage should be withdrawn. Store the gage in its case away from temperature extremes to maintain calibration stability and protect the gaging surface.
