Vermont Gage 111421850 Class Zz Minus Plug Pin Gage 0.2185 in

Product Description

The VERMONT GAGE 111421850 is a Class ZZ minus tolerance plug pin gage ground to a 0.2185-inch nominal diameter. It is used to verify that a drilled, reamed, or bored hole does not exceed its maximum allowable size, functioning as a NoGo member in a go/no-go inspection routine. The gage is manufactured from steel with a 10-microfinish surface coating and measures 2 inches in overall length. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Machinists, quality control inspectors, and toolroom technicians rely on this type of pin gage for fast, repeatable dimensional verification at the point of production or in a metrology lab.

This pin gage is suited for NoGo hole inspection in manufacturing, machining, and quality assurance environments. It is also used to set and verify micrometers, verniers, and other precision measuring devices requiring a known reference diameter. The 0.2185-inch size fits inspection requirements common in light mechanical, aerospace, and precision-parts production workflows where tight hole tolerances must be confirmed before assemblies proceed.

Key Features

• Class ZZ minus tolerance for NoGo inspection applications
• 0.2185-inch nominal diameter with 0.0002-inch tolerance
• Steel construction with 10-microfinish surface coating for accurate, repeatable contact
• 2-inch overall length for easy single-hand use
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for NoGo hole inspection and as a reference standard for micrometers, verniers, and other precision measuring devices requiring a 0.2185-inch diameter reference.

Installation Notes

Pin gages are handled and stored by quality control inspectors and toolroom personnel following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Never force a pin gage into a hole; if resistance is felt, the hole is undersized or contains burrs that must be addressed before reinspection. Store in a protective case away from temperature extremes to maintain dimensional stability.
