Vermont Gage 111217300 Class Zz Minus Plug Pin Gage 0.1730 in

Product Description

The VERMONT GAGE 111217300 is a Class ZZ minus tolerance plug pin gage machined to a nominal diameter of 0.1730 inches with an overall length of 2 inches. It is used to perform NoGo dimensional inspection of bored, drilled, or reamed holes to confirm that a feature does not exceed its maximum material condition. The steel construction and 10 microfinish surface finish deliver consistent, repeatable contact. Each gage ships with a Certificate of Accuracy traceable to NIST standards, meeting the documentation requirements of most quality management systems. Machinists, tool and die makers, and quality technicians are the primary users of this type of gage.

This pin gage is suited for use in machine shops, manufacturing cells, and inspection departments where hole diameter must be verified to tight tolerances. Beyond NoGo hole inspection, it is also appropriate for setting and verifying micrometers, verniers, and other measuring devices. The Class ZZ tolerance classification designates a working-grade gage intended for production inspection rather than master or reference standards. Its compact size makes it practical for bench inspection and in-process checks on a variety of workpiece materials and configurations.

Key Features

• Nominal measurement diameter of 0.1730 inches for precise NoGo hole inspection
• Class ZZ minus tolerance of 0.0002 inches for working-grade production use
• Steel construction with 10 microfinish surface for repeatable, accurate contact
• Overall length of 2 inches for easy handling and bench use
• Includes Certificate of Accuracy with NIST traceability for quality system compliance
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed as a working-grade NoGo plug pin gage for production inspection of holes and bores, and for calibrating or setting hand measuring instruments such as micrometers and verniers.

Installation Notes

Plug pin gages are handled and used by machinists and quality inspection personnel following standard metrology practices. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Clean the gage pin and the workpiece bore before use to ensure accurate contact and prevent measurement error. Do not force the pin into an undersized hole, as this can damage both the gage and the workpiece.
