Vermont Gage 901100600 Class Zz Plug Gage Set 125 Pc

Product Description

The VERMONT GAGE 901100600 is a Class ZZ plug gage set covering a diameter range of 0.501 to 0.625 inches in 125 individual pieces. Each plug gage holds a plus tolerance of 0.0002 inches, conforming to Class ZZ standards for general-purpose GO gaging inspection. The gages are manufactured from steel with a black oxide finish for corrosion resistance and long service life. A Certificate of Accuracy with NIST traceability is included with the set, making it suitable for calibration-controlled environments. This set is used by quality control technicians, tool-and-die shops, and precision machinists who require reliable, documented gage standards on the shop floor or in the inspection room.

This plug gage set is well suited for a range of inspection and measurement tasks in manufacturing, maintenance, and metrology applications. Typical uses include measuring hole diameters, gaging slot widths and locations, calculating distances between holes, and setting micrometers, verniers, and other measuring devices to a known reference. The 125-piece coverage across the 0.501 to 0.625 inch range provides fine incremental steps, reducing the need for multiple separate sets in this size window. Both production floor inspectors and quality assurance personnel will find this set applicable to general machined-part inspection workflows.

Key Features

• Class ZZ designation with plus tolerance of 0.0002 inches per gage
• 125-piece set spanning 0.501 to 0.625 inches in fine increments
• Steel construction with black oxide finish for durability and corrosion resistance
• NIST traceable Certificate of Accuracy included for calibration-controlled environments
• Suitable for GO gaging, hole diameter measurement, slot inspection, and reference-setting applications

Compatibility

Designed as a general-purpose Class ZZ plug gage set for use with standard gage handles and holders sized for the 0.501 to 0.625 inch diameter range. Applicable across machining, tooling, and quality inspection environments where NIST traceable Class ZZ tooling is required.

Installation Notes

Plug gages in this size range are handled and used by quality technicians and precision machinists; no power tools or utilities need to be shut down for standard gage inspection procedures. Store gages in their designated case when not in use to prevent surface damage and maintain tolerance integrity. Clean contact surfaces before use to remove oils, chips, or debris that could affect measurement accuracy. Follow your facility calibration schedule and reference the included NIST traceable Certificate of Accuracy to maintain traceability records.
