Vermont Gage 111117100 Class Zz Plus Plug Gage 0.171 in

Product Description

The VERMONT GAGE 111117100 is a Class ZZ Plus plug gage designed for precise bore and hole inspection in machining and quality control environments. Measuring a nominal diameter of 0.171 inches with a tolerance of 0.0002 inches, this gage delivers the accuracy required for Go inspection tasks. Manufactured from tool steel and finished to a 10 microfinish surface, it provides consistent, repeatable measurement performance. The 111117100 ships with a Certificate of Accuracy with NIST Traceability, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrology professionals rely on this type of instrument for tight-tolerance verification work.

This plug gage is used in Go inspection applications to verify that a hole or bore falls within its specified minimum material condition. It is suited for use alongside set micrometers, verniers, and other precision measuring devices in machine shops, manufacturing facilities, and inspection departments. At 2.0 inches overall length, it fits standard plug gage handles and is appropriate for both production-floor and laboratory inspection settings where ASME B89.1 compliance is required.

Key Features

• 10 microfinish surface for consistent contact and wear resistance
• Tool steel construction for durability in repeated-use inspection environments
• Includes Certificate of Accuracy with NIST Traceability
• Conforms to ASME B89.1 dimensional standards

Compatibility

Designed for use as a Go plug gage in standard gage handle systems for inspecting holes and bores at a 0.171 inch nominal diameter. Compatible with set micrometers, verniers, and other precision measuring devices per the manufacturer application specification.

Installation Notes

Plug gages are handled and used by qualified machinists or quality inspection technicians. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Clean the gage and the workpiece bore before inspection to avoid false readings caused by debris or coolant residue. Never force the gage into a hole; apply only light, even hand pressure consistent with Go gage inspection practice.
