Vermont Gage 911109400 Class Zz Plus Plug Gage 0.094 in

Product Description

The VERMONT GAGE 911109400 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. Measuring a nominal diameter of 0.094 inches with a tolerance of 0.0002 inches, this gage is manufactured from tool steel and finished with a black oxide coating for corrosion resistance and durability. Overall length is 2.0 inches, keeping the gage compact and easy to handle during close-tolerance work. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming conformance to ASME B89.1 standards. Quality control technicians, machinists, and tool room inspectors rely on this type of gage for reliable, repeatable go-inspection measurements.

This plug gage is suited for go inspection applications where a fixed-limit check of a small bore is required. It is used alongside micrometers, verniers, and other measuring devices to verify part conformance during production, incoming inspection, or final quality checks. The Class ZZ Plus designation indicates enhanced tolerance control beyond standard Class ZZ, making it appropriate for work where tighter dimensional verification is needed. The compact 2.0-inch overall length allows access to shallow bores and restricted inspection points in machined components.

Key Features

• Nominal measurement diameter of 0.094 inches for small-bore go inspection
• Tolerance of 0.0002 inches conforming to ASME B89.1 standards
• Tool steel construction for hardness and long service life
• Black oxide finish provides corrosion resistance without dimensional buildup

• Compact 2.0-inch overall length for access to tight inspection areas

Compatibility

Designed for use in go inspection applications and for setting or verifying micrometers, verniers, and other measuring devices requiring a 0.094-inch reference diameter.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists and require no permanent installation. Store the gage in its protective case and avoid contact with abrasive surfaces to preserve the finished diameter. Clean bore surfaces before gaging to prevent debris from affecting readings or damaging the gage. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin contact.
