Vermont Gage 111233200 Class Zz Minus Plug Pin Gage 0.3320 in

Product Description

The VERMONT GAGE 111233200 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo dimensional inspection on bored holes, drilled passages, and precision-machined features. The gage measures a nominal diameter of 0.3320 inches with a tolerance of 0.0002 inches, making it suitable for verifying that a feature does not exceed its maximum material condition. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards. This type of gage is handled daily by machinists, quality technicians, and tool-room inspectors working to print tolerances in production and inspection environments.

Class ZZ Minus pin gages are used in NoGo inspection applications where confirming a hole or bore has not been undercut beyond tolerance is critical. They are also referenced when setting micrometers, verniers, and other comparative measuring devices to a known diameter. Typical use cases include in-process inspection on CNC machined parts, receiving inspection of vendor-supplied components, and first-article verification. The 0.3320-inch diameter covers a common drill and reamed hole size found across general machining, tooling, and light manufacturing work.

Key Features

• Class ZZ Minus tolerance of 0.0002 inches for NoGo go-gauge inspection
• Steel construction for durability in production and tool-room environments
• 10 microfinish surface coating for consistent, repeatable contact
• NIST-traceable Certificate of Accuracy included with each gage
• Compact 2-inch overall length for easy handling in confined inspection setups
• Suitable for setting micrometers, verniers, and other comparative measuring devices

Compatibility

Designed as an OEM-style pin gage for NoGo inspection of features at 0.3320-inch nominal diameter, and for use as a reference standard when setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Pin gages are handled and used by quality technicians and machinists - no permanent installation is required. Before use, clean the gage and the feature being inspected to remove chips, oil, and debris that could affect the measurement. Never force a pin gage into a hole; hand pressure only is appropriate to avoid damage to the gage or the workpiece. Store the gage in its protective sleeve or case when not in use to preserve the surface finish and calibration integrity.
