Vermont Gage 112203300 Class Zz Minus Plug Pin Gage 3.30 Mm

Product Description

The VERMONT GAGE 112203300 is a Class ZZ minus plug pin gage ground to a 3.30 mm diameter with a tolerance of 0.00508 mm. It is used to perform NoGo inspection checks on bored, drilled, or reamed holes to confirm that a hole has not been made oversized beyond the allowable limit. The gage body is steel construction with a 10 microfinish surface coating for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Machinists, quality technicians, and tool-room professionals use this gage in production inspection and measuring-device calibration workflows.

This gage is designed for NoGo hole inspection applications and is also suited for setting and verifying micrometers, verniers, and other precision measuring devices. At 2 inches in overall length and 0.01 pounds, it is compact enough for bench use or inclusion in a gage pin set. It is appropriate for use in manufacturing, machine shop, and quality-control environments where tight-tolerance hole verification is required.

Compatibility

Designed for NoGo hole inspection and for setting or verifying micrometers, verniers, and other precision measuring devices requiring a 3.30 mm reference diameter.

Installation Notes

Plug pin gages are handled and stored by quality technicians and tool-room personnel following standard gage-handling procedures. Clean the gage and the workpiece bore before use to prevent debris from affecting the measurement result. Do not force the gage into a bore; light hand pressure is the correct technique for Go and NoGo checks. Store in a protective case away from temperature extremes to preserve calibration integrity.
