Vermont Gage 111450250 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 111450250 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. Manufactured from steel, this pin gage has a nominal diameter of 0.5025 inches and an overall length of 2 inches. The Class ZZ tolerance grade of 0.0002 inches makes it appropriate for NoGo inspection applications where verifying that a hole or bore does not exceed a maximum allowable size is required. Each unit ships with a Certificate of Accuracy with NIST traceability, providing documented evidence of calibration compliance for quality control recordkeeping.

This plug pin gage is used in dimensional inspection workflows across manufacturing, machining, and fabrication environments. Its primary application is NoGo gauging, confirming that bores, holes, and openings have not exceeded their maximum tolerance limits. It is also suitable for setting and verifying micrometers, verniers, and other measuring devices. Quality control technicians, machinists, and metrology personnel typically use this gage during incoming inspection, in-process checks, and final part verification.

Key Features

• Class ZZ Minus tolerance grade at 0.0002 inches for NoGo inspection applications
• Steel construction for durability and dimensional stability
• 0.5025 inch nominal diameter with 2 inch overall length
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Suitable for setting micrometers, verniers, and other precision measuring instruments

Compatibility

Designed as a Class ZZ Minus plug pin gage for use in NoGo inspection applications and for setting micrometers, verniers, and comparable measuring devices in standard dimensional inspection programs.

Installation Notes

Plug pin gages are handled and used by quality control technicians and machinists in controlled inspection environments. Store the gage in its protective case when not in use to prevent nicks, corrosion, or dimensional changes. Clean the gage and the part being inspected before use to ensure accurate results. Apply only light hand pressure when inserting the pin into a bore — forcing the gage can damage both the gage and the workpiece.
