Vermont Gage 911306250 Class Zz Plus Plug Pin Gage

Product Description

The VERMONT GAGE 911306250 is a Class ZZ Plus plug pin gage with a 0.0625-inch (1/16-inch) diameter, manufactured from steel with a black oxide finish. Plug pin gages are precision measurement tools used to verify bore and hole diameters to a known tolerance class. Class ZZ Plus designates a commercial-grade tolerance standard suitable for inspection and quality control in machine shops, tool rooms, and manufacturing environments. Each gage ships with a Certificate of Accuracy traceable to NIST standards, confirming dimensional integrity at the time of manufacture. Machinists, quality technicians, and tool-and-die professionals rely on pin gages of this type for fast, repeatable go/no-go checks on small-diameter features.

This pin gage is suited for inspecting precision holes, bores, and slots in both production and inspection settings. The 0.0625-inch diameter targets small-bore applications common in precision machining, hydraulic components, and instrument assembly. The black oxide finish provides mild corrosion resistance while maintaining dimensional accuracy across the gage surface. This gage is intended for bench or hand use and does not require a fixture or handle for standard inspection tasks, though optional gage handles are commonly used for higher-volume or ergonomic applications.

Key Features

• 0.0625-inch (1/16-inch) diameter for small-bore inspection
• Class ZZ Plus tolerance grade for commercial-grade go/no-go gauging
• Steel construction with black oxide finish for durability and mild corrosion resistance
• Includes Certificate of Accuracy with NIST traceability
• Lightweight at 0.1 pounds for easy single-hand use

Compatibility

Designed as a standard replacement or standalone plug pin gage for use in any inspection process requiring a 0.0625-inch Class ZZ Plus diameter reference. Compatible with standard gage handle holders sized for pin gages of this diameter.

Installation Notes

Pin gages are installed and handled by machinists and quality control technicians without the need for tools. Keep the gage clean and lightly oiled when not in use to prevent corrosion and preserve dimensional accuracy. Do not force the gage into a bore; insertion should be smooth and free of lateral pressure to avoid deflection or damage to the gage surface. Store separately from other metal tools to prevent contact damage to the precision-ground diameter.
