Vermont Gage 111309750 Class Zz Plus Plug Gage 0.0975 in

Product Description

The VERMONT GAGE 111309750 is a Class ZZ Plus plug gage used to inspect and verify hole diameters in precision machining and quality control applications. It measures 0.0975 inches in diameter with a tolerance of 0.0002 inches, meeting ASME B89.1 standards for dimensional gaging accuracy. The gage body is machined from tool steel and features a 10 microfinish surface for consistent contact and repeatable readings. A Certificate of Accuracy with NIST Traceability is included, making it suitable for calibrated inspection environments. Machinists, quality technicians, and metrology lab personnel are the primary users of this tool.

This plug gage is used in go inspection applications to confirm that bored, drilled, or reamed holes fall within tolerance. It is also used to set and verify micrometers, verniers, and other measuring devices. The 0.0975-inch diameter makes it appropriate for small-bore inspection tasks found in precision component manufacturing, toolroom work, and incoming or in-process quality checks. Its overall length of 2.0 inches provides a comfortable handling profile for bench or floor-level inspection use.

Key Features

• 0.0975-inch measurement diameter with 0.0002-inch tolerance per ASME B89.1
• Class ZZ Plus designation for go inspection of hole diameters
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface for consistent, repeatable contact
• Includes Certificate of Accuracy with NIST Traceability
• 2.0-inch overall length for practical bench use

Compatibility

Designed for use in go inspection applications and as a reference standard for setting micrometers, verniers, and other measuring devices. Compatible with standard plug gage handles sized for small-diameter gage members.

Installation Notes

Plug gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin contact. Store the gage in its protective case when not in use to preserve the microfinish surface and dimensional integrity. Do not force the gage into a hole that is undersized, as this will damage the gage and compromise its accuracy. Periodic recalibration by a qualified metrology technician is recommended to maintain NIST-traceable accuracy over time.
