Vermont Gage 112409690 Class Zz Minus Plug Pin Gage 9.69 Mm

Product Description

The VERMONT GAGE 112409690 is a Class ZZ Minus plug pin gage used to perform NoGo inspection of bored holes, machined features, and precision-fit components. Manufactured from steel with a 10 microfinish surface coating, it measures a nominal diameter of 9.69 mm with a tolerance of 0.00508 mm. The gage ships with a Certificate of Accuracy traceable to NIST, making it suitable for calibrated inspection work in machine shops, metrology labs, and quality control environments. Machinists, quality technicians, and tool-room inspectors rely on this type of gage to verify that a feature has not been undercut beyond its acceptable limit.

This plug pin gage is designed for NoGo inspection applications where a precise go/no-go acceptance decision is required. It is also used to set and verify micrometers, verniers, and other dimensional measuring devices. At 2 inches overall length and 0.07 pounds, the gage is suited for bench-top inspection and portable field verification in manufacturing and precision machining environments where tight dimensional tolerances must be confirmed.

Key Features

• Steel construction with 10 microfinish surface coating for durability and accurate contact
• Certificate of Accuracy included with NIST traceability for calibrated inspection records
• Compatible with setting micrometers, verniers, and other precision measuring devices
• Compact 2-inch overall length for easy handling at the bench or in the field

Compatibility

Designed for NoGo inspection use and for setting micrometers, verniers, and other precision measuring devices requiring a 9.69 mm reference diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists following standard metrology practices. Clean the gage and the feature under inspection before use to remove chips, oil, or debris that could affect the measurement. Store the gage in a protective case when not in use to prevent surface damage to the precision-ground diameter. Do not force the gage into a feature; resistance indicates the feature is within the NoGo rejection zone.
