Vermont Gage 102300300 Class Zz Plug Gage Set 250 Pc

Product Description

The VERMONT GAGE 102300300 is a Class ZZ plug gage set covering a diameter range of 5.01 to 9.99 mm in 250 individual steel plug gages. Each gage carries a plus tolerance of 0.005 mm, providing the measurement precision required for hole diameter inspection, slot width verification, and transfer calibration of micrometers, verniers, and other precision measuring devices. Every piece in the set is supplied with a Certificate of Accuracy traceable to NIST standards. This set is intended for use by machinists, quality control technicians, and tool room professionals who require reliable, traceable go-gage references in production and inspection environments.

This plug gage set is suited for shop floor and metrology lab applications where hole location, diameter conformance, and inter-hole distance calculations must be verified against a traceable standard. Typical use cases include GO gaging inspection during in-process quality checks, setting and verifying micrometers and verniers before measurement runs, and checking slot widths and locations on machined components. The 250-piece range provides continuous diameter coverage from 5.01 mm through 9.99 mm, making the set practical for facilities working across a broad range of bore sizes without gaps in coverage.

Key Features

• 250-piece set covering 5.01 to 9.99 mm diameter range in sequential increments
• Class ZZ tolerance classification with plus tolerance of 0.005 mm per gage
• Steel construction for durability and dimensional stability in shop environments
• Certificate of Accuracy included with each set, NIST traceable
• Suitable for GO gaging inspection, hole diameter measurement, slot width and location checks, and transfer calibration of measuring instruments

Compatibility

Designed as a general-purpose Class ZZ plug gage set for use with any application requiring go-gage inspection or precision bore measurement in the 5.01 to 9.99 mm diameter range.

Installation Notes

Plug gages should be handled and stored by trained metrology or quality control personnel. Clean gage surfaces and the workpiece bore before use to prevent debris from affecting readings or causing surface damage. Apply a light coat of gage oil or rust-preventive when storing to protect steel surfaces. Gages should be returned to their case and stored away from heat sources and corrosive environments to maintain calibration integrity.
