Vermont Gage 111440650 Class Zz Minus Plug Pin Gage 0.4065 in

Product Description

The VERMONT GAGE 111440650 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in precision measurement workflows. Machined from steel with a 10 microfinish coating, it measures 0.4065 inches in diameter with a tolerance of 0.0002 inches. At 2 inches in overall length, this pin gage is sized for handheld use and delivers the dimensional accuracy required for reliable go/nogo inspection decisions. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming it meets Class ZZ tolerancing standards. Machinists, quality technicians, and tool-and-die professionals rely on this type of gage for repeatable hole and bore verification.

This pin gage is suited for use in inspection rooms, on the shop floor, and in toolroom environments where precise hole diameter verification is required. It is also appropriate for setting and calibrating micrometers, verniers, and other measuring devices that require a known reference diameter. The Class ZZ Minus designation makes it the correct choice for NoGo member applications in standard two-piece plug gage sets. It is used in both production inspection and quality assurance roles across general manufacturing, aerospace, and automotive machining environments.

Installation Notes

Handle pin gages with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in the original protective case when not in use to avoid surface damage that could affect measurement accuracy. Clean the gage and the workpiece bore before use to remove debris that may produce false readings. This gage should be handled and applied by qualified metrology or machining personnel familiar with Class ZZ gage standards.
