Vermont Gage 111403550 Class Zz Minus Plug Pin Gage 0.0355 in

Product Description

The VERMONT GAGE 111403550 is a Class ZZ Minus plug pin gage used to perform NoGo inspection checks on precision bores, holes, and apertures. Manufactured from steel with a 10 microfinish surface coating, this pin gage measures a nominal diameter of 0.0355 inches with a tolerance of 0.0002 inches. At an overall length of 2 inches, it is sized for use in handheld inspection workflows. Each unit ships with a Certificate of Accuracy that includes NIST traceability, meeting the documentation requirements common in regulated manufacturing and quality-control environments. Machinists, quality technicians, and metrology professionals use this gage to confirm that a feature does not exceed the maximum allowable size.

This plug pin gage is suited for shop-floor and laboratory inspection of small-diameter holes and precision-machined features in manufacturing, tooling, and production environments. The Class ZZ designation indicates a commercial-grade tolerance tier appropriate for general NoGo inspection, setting micrometers, verniers, and other measuring devices requiring a traceable reference. It is typically used in low-tolerance production lines where confirming maximum material condition is a critical step in the inspection process.

Installation Notes

Plug pin gages are handled and used by quality technicians and metrology professionals — no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Avoid dropping or side-loading the pin, as impact can alter the gage diameter and invalidate its calibration. Recertify the gage at intervals consistent with your facility quality management plan or applicable metrology standards.
