Vermont Gage 901100800 Class Zz Plug Gage Set 82 Pc

Product Description

The VERMONT GAGE 901100800 is a Class ZZ plug gage set designed to measure and inspect hole diameters and feature locations across a range of 0.751 to 0.832 inches. Built from steel with a black oxide finish, the set holds a plus tolerance of 0.0002 inches (0.0002 mm), meeting Class ZZ inspection standards. Each set includes 82 individual plug gages and ships with a Certificate of Accuracy that is NIST Traceable. Licensed metrologists, quality control inspectors, and precision machining professionals use this set to verify dimensional conformance on the shop floor or in the inspection lab.

This plug gage set is suited for both production and inspection environments where repeatable, traceable measurement is required. Typical applications include GO gaging inspection, measuring hole diameters, gaging slot widths and locations, calculating distances between holes, and setting micrometers, verniers, and other measuring devices. The 0.751 to 0.832 inch range covers a commonly specified bore size window in general machining, tooling, and fixture work. The complete 82-piece configuration reduces the need for multiple individual gages across this range.

Compatibility

Designed as an OEM-style Class ZZ plug gage set suitable for use with standard gage handles and holders configured for the 0.751 to 0.832 inch diameter range.

Installation Notes

Plug gages should be handled and stored by trained quality or metrology personnel following applicable dimensional inspection procedures. Clean measuring surfaces and inspect for burrs or damage before use. Store gages in the provided case away from extreme temperature variation to preserve calibration integrity. Periodic recalibration against a NIST-traceable reference standard is recommended per your facility quality management plan.
