Vermont Gage 112207380 Class Zz Minus Plug Pin Gage 7.38mm

Product Description

The VERMONT GAGE 112207380 is a Class ZZ Minus plug pin gage designed for NoGo inspection of bored, reamed, or machined holes with a nominal diameter of 7.38 mm. Manufactured from steel with a 10 microfinish surface coating, this pin gage delivers a tolerance of 0.00508 mm, meeting Class ZZ minus standards for dimensional verification in production and quality-control environments. At 2 inches overall length, it fits standard pin gage handles and is appropriate for use with micrometers, verniers, and other precision measuring devices. Machinists, quality technicians, and tool-room professionals rely on this gage for fast, reliable go/no-go hole inspection on the shop floor or in the inspection lab.

This pin gage is suited for incoming inspection, in-process checks, and final inspection tasks in manufacturing environments. Its NoGo application confirms that a hole has not been bored or reamed beyond its maximum material condition limit. Typical uses include verifying toleranced holes in metal fabrication, precision machining, and assembly operations where hole diameter control is critical. The included Certificate of Accuracy with NIST traceability supports quality management system documentation requirements such as ISO 9001 or AS9100 audit records.

Key Features

• 7.38 mm nominal diameter targets a specific hole size in standard metric tolerance systems
• Steel construction with 10 microfinish surface coating for durability and accurate seating in the hole
• 2 inches overall length compatible with standard pin gage handles and accessories
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Suitable for use with micrometers, verniers, and other calibrated measuring devices

Compatibility

Designed for use as a NoGo inspection pin gage and compatible with set micrometers, verniers, and other precision measuring devices. Fits standard pin gage handles accepting 7.38 mm diameter pins.

Installation Notes

Pin gages should be handled by quality or metrology technicians following established gage handling procedures. Clean the pin and the hole being inspected before use to remove chips, oil, or debris that could affect measurement accuracy. Store the pin gage in a protective case away from other metal tooling to prevent surface damage. Do not force the pin into a hole; a NoGo pin should not enter a correctly toleranced hole under light hand pressure.
