Vermont Gage 112422330 Class Zz Minus Plug Pin Gage 22.33mm

Product Description

The VERMONT GAGE 112422330 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection of bored holes, machined features, and precision-fit components. It measures a nominal diameter of 22.33 mm with a tolerance of 0.00508 mm, meeting Class ZZ Minus specification for go/no-go gauging applications. Each unit ships with a Certificate of Accuracy that carries NIST traceability, making it suitable for quality control environments that require documented calibration records. Machinists, toolroom technicians, and quality inspectors use this gage to verify that a hole or feature does not exceed its maximum allowable material condition.

This pin gage is intended for NoGo inspection tasks on production floors, toolrooms, and inspection stations. It is also used to set and verify micrometers, verniers, and other measuring devices that require a known reference diameter. The 2-inch overall length provides adequate reach for most shallow-bore and surface-feature inspection scenarios. The 10 micro coating and finish helps resist wear and corrosion during regular handling and storage.

Key Features

• 22.33 mm nominal measurement diameter
• Steel construction with 10 micro coating and finish for durability and corrosion resistance
• Includes Certificate of Accuracy with NIST traceability for documented quality control
• 2-inch overall length suitable for shallow bore and surface feature inspection
• Compatible with use as a reference standard for micrometers, verniers, and similar measuring devices

Compatibility

Designed for NoGo inspection gauging and for setting or verifying micrometers, verniers, and other precision measuring devices requiring a traceable reference diameter of 22.33 mm.

Installation Notes

Pin gages are handled by quality inspectors and toolroom technicians and require no power source or mechanical installation. Store the gage in its protective case when not in use to prevent damage to the gauging surface. Clean the gage surface before use to remove oils, chips, or debris that could affect measurement accuracy. Avoid dropping or forcing the gage into a feature, as impact damage will affect tolerance integrity and may invalidate the NIST-traceable certification.
