Vermont Gage 112205240 Class Zz Minus Plug Pin Gage 5.24mm

Product Description

The VERMONT GAGE 112205240 is a Class ZZ Minus plug pin gage designed for NoGo inspection work in precision measurement applications. Machined from steel with a 10 microfinish surface coating, this gage measures a nominal diameter of 5.24 mm with a tolerance of 0.00508 mm, meeting Class ZZ minus standards for go/no-go verification. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy backed by NIST traceability, giving metrology labs and quality control departments a documented calibration reference. Installation and use require no tools beyond proper gage handling technique, making it a straightforward addition to any inspection station.

This plug pin gage is suited for NoGo hole inspection in manufacturing quality control environments, tool rooms, and metrology labs. It is also used to set micrometers, verniers, and other precision measuring devices requiring a certified reference standard. The 5.24 mm size fits applications where close-tolerance bore verification is required, such as machined component inspection in light manufacturing, aerospace part verification, or general precision fabrication shops. Dimensional verification work of this type is typically performed by quality control technicians or machinists.

Key Features

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and other precision measuring devices where a certified 5.24 mm diameter gage pin is required.

Installation Notes

Plug pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and dimensional contamination from skin oils. Store the gage in its protective case when not in use and keep it away from magnetic fields and abrasive surfaces. Periodic recalibration against a certified reference standard is recommended per your facility quality management plan. No special tools are required for use, but the gage should be inspected for wear or damage before each measurement session.
