Vermont Gage 112203540 Class Zz Minus Plug Pin Gage 3.54 Mm

Product Description

The VERMONT GAGE 112203540 is a Class ZZ minus plug pin gage designed for precise dimensional inspection in machining and metrology applications. This single-pin gage measures 3.54 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where tight dimensional control is required. The gage measures 2 inches in overall length and is manufactured from steel with a 10 microfinish coating for consistent surface quality. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Machinists, quality technicians, and tool room inspectors rely on this type of gage for verifying bore and hole dimensions on production parts.

This pin gage is used in NoGo inspection roles to confirm that a bore or hole does not exceed the maximum allowable size. It is also compatible with setup and calibration tasks involving micrometers, vernier calipers, and other precision measuring devices. Typical applications include incoming inspection, first-article inspection, and in-process quality control in job shops, production facilities, and metrology labs. The Class ZZ designation indicates a commercial-grade tolerance class appropriate for general inspection use rather than master or reference standards.

Key Features

• 3.54 mm diameter with 0.00508 mm tolerance for precise dimensional verification
• Steel construction with 10 microfinish surface coating
• 2 inch overall length for standard hand-held use
• Includes Certificate of Accuracy with NIST traceability
• Compatible with micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use in NoGo inspection applications and for setting or verifying micrometers, vernier calipers, and other precision measuring devices requiring a 3.54 mm reference diameter.

Installation Notes

Pin gages are handled and used by quality technicians and machinists and require no installation in the traditional sense. Store the gage in its protective case when not in use to prevent surface damage or contamination that could affect measurement accuracy. Clean the gage pin and the bore being checked before use to remove chips, oil, or debris. Never force a pin gage into a hole — if the pin does not enter freely under light hand pressure during a NoGo check, the inspection result is confirmed without forcing.
