Vermont Gage 911110900 Class Zz Plus Plug Gage 0.109 in

Product Description

The VERMONT GAGE 911110900 is a Class ZZ Plus plug gage designed for precision go inspection of hole diameters in manufactured parts. Built from tool steel with a black oxide finish, this gage measures a nominal diameter of 0.109 inches with a tolerance of 0.0002 inches. At 2.0 inches in overall length and weighing approximately 0.1 pounds, it is a compact, single-ended inspection tool suited for quality control workflows on the shop floor or in a metrology lab. Each unit ships with a Certificate of Accuracy that includes NIST traceability, confirming conformance to ASME B89.1 standards.

This plug gage is used in go inspection applications to verify that a drilled, reamed, or machined hole meets minimum size requirements. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices requiring a known reference diameter. Typical users include machinists, quality control inspectors, and toolroom technicians working in precision manufacturing environments where tight hole tolerances are a specification requirement.

Key Features

• Class ZZ Plus tolerance grade at 0.0002 inches for precise go inspection
• Tool steel construction for durability and dimensional stability
• Black oxide finish provides corrosion resistance and reduces glare during inspection
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 gage standards
• Compact 2.0 inch overall length suits tight-clearance inspection setups

Compatibility

Designed as a go inspection plug gage for checking 0.109 inch nominal diameter holes. Also suitable for setting micrometers, verniers, and other precision measuring devices requiring a calibrated reference diameter.

Installation Notes

Plug gages are handled and used by quality control inspectors and toolroom technicians, not installed in the field. Before use, clean the gage and the hole being inspected to remove chips, coolant, and debris that could affect the measurement. Apply light gaging oil when appropriate to protect the gage surface and reduce wear. Store the gage in its case away from temperature extremes to maintain dimensional accuracy over time.
