Vermont Gage 911108700 Class Zz Plus Plug Gage 0.087 in

Product Description

The VERMONT GAGE 911108700 is a Class ZZ Plus plug gage used to verify bore and hole dimensions in precision machining and inspection workflows. Measuring 0.087 inches in diameter with a tolerance of 0.0002 inches, this gage is manufactured from tool steel with a black oxide finish for corrosion resistance and durability. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality control processes. It is designed for go inspection use, confirming that a hole or bore meets its lower dimensional limit.

This plug gage is suited for dimensional inspection in machine shops, toolrooms, and manufacturing environments where tight tolerances must be verified consistently. It is used alongside micrometers, verniers, and other precision measuring devices as part of a structured inspection routine. Applications include go inspection of drilled, reamed, or bored holes in metal components where ASME B89.1 compliance is required. Machinists, quality control technicians, and metrologists working in job shops or production facilities are the primary users of this gage.

Key Features

• 0.087 inch nominal diameter with 0.0002 inch Class ZZ Plus tolerance
• Tool steel construction for wear resistance and dimensional stability
• Black oxide finish provides corrosion protection and reduces glare during inspection
• Includes Certificate of Accuracy with NIST traceability for audit and quality documentation
• Meets ASME B89.1 standard for gage dimensional requirements
• 2.0 inch overall length for comfortable single-hand use on standard workpiece depths

Compatibility

Designed for use with go inspection routines and compatible with micrometers, verniers, and other precision measuring devices as noted in the product specification. Suitable for any application requiring ASME B89.1 compliant plug gage inspection at the 0.087 inch diameter range.

Installation Notes

Plug gages are handled and used by machinists and quality control technicians; no permanent installation is required. Store the gage in a protective case when not in use to prevent damage to the gaging surfaces. Clean the gage and the workpiece bore before each measurement to avoid false readings caused by debris or coolant. Never force the gage into a hole; apply light, consistent hand pressure only to protect the gage and the workpiece.
