Vermont Gage 112202720 Class Zz Minus Plug Pin Gage 2.72mm

Product Description

The VERMONT GAGE 112202720 is a Class ZZ Minus plug pin gage used to verify that a bored or reamed hole does not exceed its maximum allowable size. Manufactured from steel with a 10 microfinish surface coating, this pin gage measures 2.72 mm in diameter and carries a tolerance of 0.00508 mm. At 2 inches in overall length, it is sized for handheld use in production and inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting standard documentation requirements for calibrated inspection tooling. Metrology technicians, machinists, and quality control inspectors use this gage in dimensional verification workflows.

This pin gage is designed for NoGo inspection applications, confirming that a feature is within its upper-limit tolerance. It is also suited for setting and verifying micrometers, verniers, and other precision measuring devices. Typical use environments include machine shops, manufacturing cells, and quality labs where tight bore tolerances must be verified quickly and reliably. The compact 2-inch length allows easy access to shallow bores and countersunk features. Its Class ZZ rating is appropriate for general-purpose inspection and is a recognized standard in dimensional metrology.

Key Features

• Class ZZ Minus tolerance class for NoGo inspection of bores at maximum material condition
• 2.72 mm nominal diameter with 0.00508 mm tolerance for precise dimensional verification
• Steel construction with 10 microfinish surface coating for durability and accurate gauging contact
• 2-inch overall length for handheld use and access to shallow features
• Includes Certificate of Accuracy with NIST traceability for documentation and audit compliance

Compatibility

Designed for use as a NoGo plug gage in dimensional inspection setups and for setting micrometers, verniers, and other precision measuring devices that accept 2.72 mm reference pins.

Installation Notes

Pin gages are installed and used by metrology technicians and quality inspectors; no special tools are required beyond clean, dry handling practices. Before use, inspect the gage and the feature being measured for burrs, chips, or contamination that could cause a false reading or damage the gage surface. Never force a plug pin gage into a bore; the gage should enter or be rejected by the feature under light hand pressure only. Store in a protective case away from other metal tooling to prevent surface damage that would affect calibration.
