Vermont Gage 111292500 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 111292500 is a Class ZZ Minus plug pin gage machined from steel and used to verify that a drilled or reamed hole does not exceed its maximum allowable size. At 0.9250 inches in diameter with a tolerance of 0.0002 inches, this gage performs the NoGo function in a go/no-go inspection routine. The overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements common in quality-controlled manufacturing and inspection environments. The 10 micro finish on the gage surface supports repeatable, consistent seating during measurement.

This plug pin gage is used in precision inspection applications where hole diameter must be held to close tolerances. Typical users include quality control technicians, machinists, and toolroom personnel working with set micrometers, verniers, and other measuring devices. It is suited for both production floor inspection and bench-level dimensional verification in shops handling tight-tolerance bored, drilled, or reamed parts.

Key Features

• Class ZZ Minus tolerance class for NoGo hole inspection
• 0.9250 inch nominal diameter with 0.0002 inch tolerance
• Steel construction for durability and dimensional stability
• 10 micro surface finish for consistent, repeatable contact
• Certificate of Accuracy included with NIST traceability
• 2 inch overall length for easy handling in standard inspection setups

Compatibility

Designed for use with set micrometers, verniers, and other precision measuring devices requiring a Class ZZ Minus plug gage reference at 0.9250 inches diameter.

Installation Notes

Plug pin gages are handled and applied by quality technicians or machinists - not installed permanently. Before use, clean the gage and the bore being checked to remove chips, coolant, and debris that could affect the reading. Do not force the gage into the bore; apply light, consistent hand pressure only. Store the gage in its protective case when not in use to prevent surface damage and corrosion.
