Vermont Gage 111176300 Class Zz Plus Plug Gage 0.763 in

Product Description

The VERMONT GAGE 111176300 is a Class ZZ Plus plug gage used to perform go inspection checks on bored holes, machined features, and other precision-toleranced cylindrical openings. Manufactured from tool steel, it measures a nominal diameter of 0.763 inches with a tolerance of 0.0002 inches, making it suitable for close-tolerance production inspection work. Each gage ships with a Certificate of Accuracy with NIST traceability, confirming it meets ASME B89.1 standards. Machinists, quality technicians, and tool-and-die professionals use this gage as part of incoming inspection, process control, and final acceptance routines.

This plug gage is designed for go inspection tasks and is also compatible with setting and verifying micrometers, verniers, and other dimensional measuring devices. It is well suited for use in machine shops, production floors, and quality labs handling tight-tolerance work in both light manufacturing and precision machining environments. The 10 microfinish surface finish ensures consistent contact with the gage surface during measurement, reducing wear and preserving gage accuracy over repeated use cycles.

Compatibility

Designed for go inspection of precision-bored cylindrical features and for setting micrometers, verniers, and other dimensional measuring devices requiring a 0.763 inch reference standard.

Installation Notes

Handle plug gages with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in the provided case or a protected surface away from contaminants when not in use. Never force a plug gage into a feature; if resistance is met, remove and inspect the workpiece for burrs or debris before proceeding. Periodic cleaning and inspection per your facility's gage calibration program will maintain accuracy and extend service life.
