Vermont Gage 101400600 Class Zz Plug Gage Set 125 Pc

Product Description

The VERMONT GAGE 101400600 is a 125-piece Class ZZ plug gage set used to measure and inspect hole diameters and slot dimensions to a tolerance of 0.0002 inches (minus tolerance). Each hardened steel plug covers a size range from 0.5015 inches to 0.6255 inches, stepping through the range in fine increments. The set ships with a Certificate of Accuracy that is NIST traceable, giving quality inspectors and machinists documented confidence in every reading. Licensed metrology technicians, toolroom machinists, and quality control professionals are the primary users of this type of tooling.

This plug gage set is suited for shop-floor and laboratory inspection environments where hole diameter verification, slot width and location gaging, NO-GO inspection, and the calibration of micrometers, verniers, and other measuring devices are routine tasks. It is also used to calculate distances between holes on machined parts and fixtures. The 0.5015-to-0.6255-inch range targets mid-range bore and hole diameters commonly found in mechanical and tooling applications.

Key Features

• 125-piece set covers 0.5015 to 0.6255 inches in fine diameter increments
• Class ZZ tolerance of 0.0002 inches (minus) per plug
• Hardened steel construction for wear resistance and dimensional stability
• NIST traceable Certificate of Accuracy included with each set
• Supports multiple applications: hole diameter measurement, NO-GO inspection, slot gaging, and instrument calibration

Compatibility

Designed as a standard Class ZZ plug gage set for use in general mechanical inspection, toolroom measurement, and quality control workflows requiring NIST traceable dimensional verification in the 0.5015-to-0.6255-inch range.

Installation Notes

Plug gages are handled and used by trained metrology technicians or quality control professionals. Clean the gage and the part bore thoroughly before use to prevent debris from affecting readings or scoring the gage surface. Store gages in their designated holders or case when not in use to prevent nicks and corrosion. Follow your facility quality management procedures for gage calibration intervals and handling to maintain NIST traceability.
