Vermont Gage 111100700 Class Zz Plus Plug Gage 0.007 in

Product Description

The VERMONT GAGE 111100700 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. The gage measures 0.007 inches in diameter with a tolerance of 0.0002 inches, making it suitable for high-accuracy go inspection work. Finished to a 10 microfinish surface quality, it is manufactured from tool steel for durability and dimensional stability. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented quality assurance programs. Metrology technicians, machinist inspectors, and quality control professionals use this gage to verify bore conformance in precision manufacturing environments.

This plug gage is used in go inspection applications to verify that a bore or hole meets minimum size requirements. It is also suitable for setting and calibrating micrometers, verniers, and other measuring devices requiring a known reference diameter. The 0.007-inch size serves applications in precision machining, aerospace component inspection, medical device manufacturing, and any environment where tight tolerance verification at sub-tenth-inch diameters is required. The overall length of 2.0 inches provides a practical handle length for handheld use at the bench or on the shop floor.

Key Features

• Class ZZ Plus tolerance grade with 0.0002-inch tolerance for high-accuracy go inspection
• 0.007-inch measurement diameter for small-bore verification
• 10 microfinish surface quality for consistent, repeatable contact
• Tool steel construction for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Meets ASME B89.1 standard for dimensional gaging

Compatibility

Suitable for use as a go plug gage for bores and holes at 0.007 inches nominal diameter, and for setting micrometers, verniers, and other measuring devices requiring a precision reference at this diameter per ASME B89.1.

Installation Notes

Plug gages are handled and used by metrology technicians and quality inspectors rather than installed in a mechanical system. Store the gage in its protective case when not in use to prevent surface damage and contamination. Clean the gage and bore surfaces before use to ensure accurate measurement readings. Avoid dropping or impacting the gage, as damage to the ground surface will compromise dimensional accuracy.
