Vermont Gage 911100900 Class Zz Plus Plug Gage 0.009 in

Product Description

The VERMONT GAGE 911100900 is a Class ZZ Plus plug gage designed for precision go-inspection of small-diameter bores and holes. Measuring 0.009 inches in diameter with a tolerance of 0.0002 inches, this gage gives machinists and quality technicians a reliable tool for verifying tight tolerances in manufactured parts. The tool steel construction with a black oxide finish provides durability and corrosion resistance in shop environments. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting documentation requirements in quality management systems. Overall length is 2.0 inches, making it easy to handle in close-quarters inspection setups.

This plug gage is suited for go inspection of precision bores in production and metrology environments. It is also used to calibrate and verify the accuracy of micrometers, verniers, and other measuring devices. Typical users include quality control technicians, tool room machinists, and metrology lab personnel working to ASME B89.1 standards. The 0.009-inch diameter range addresses very fine bore tolerances common in precision mechanical, hydraulic, and instrumentation components.

Key Features

• Class ZZ Plus tolerance rating: 0.0002 inches for high-accuracy go inspection
• Tool steel construction for hardness and long service life in production environments
• Black oxide finish for corrosion resistance and reduced glare during inspection
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Meets ASME B89.1 standards for plain plug gages
• Compatible with go inspection setups, micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection use with micrometers, verniers, and other precision measuring devices requiring a 0.009-inch diameter reference standard per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and tool room personnel — no power tools or fasteners are required. Keep the gage clean and lightly oiled when stored to prevent corrosion. Never force a plug gage into a bore; apply only light, consistent hand pressure to avoid damage to the gage or the workpiece. Store in the provided case or protective sleeve away from impact and abrasive contact.
