Vermont Gage 102300200 Class Zz Plug Gage Set 185 Pc

Product Description

The VERMONT GAGE 102300200 is a Class ZZ plug gage set covering a diameter range of 1.31 mm to 4.99 mm across 185 individual pieces. Each gage is manufactured from steel and held to a plus 0.005 mm tolerance, making this set suitable for precision hole inspection and measurement tasks in machine shops, quality control departments, and toolroom environments. Every set ships with a Certificate of Accuracy traceable to NIST standards, providing the documentation required for ISO and AS9100 audit trails. Metrologists, machinists, and quality technicians rely on sets like this for repeatable, traceable dimensional verification.

This plug gage set is used in applications where precise hole diameter verification, slot width measurement, or inter-hole distance calculation is required. Typical use cases include GO gaging inspection of drilled or reamed holes, setting micrometers and vernier calipers to known dimensions, and verifying slot widths and locations on machined components. The 185-piece range provides continuous coverage from 1.31 mm to 4.99 mm, eliminating the need for multiple individual gages across this size band. Suited for both production floor inspection and toolroom calibration work.

Compatibility

Designed for use as a Class ZZ plug gage set in standard precision measurement and inspection applications requiring coverage of the 1.31 mm to 4.99 mm diameter range.

Installation Notes

Plug gages should be handled by metrology or quality technicians following standard gage handling procedures. Clean all gages and work surfaces before use to prevent contamination that could affect measurement accuracy. Store gages in the provided case away from heat sources and corrosive environments to preserve dimensional integrity. Calibration intervals should be established per your facility's quality management system requirements.
