Vermont Gage 111167800 Class Zz Plus Plug Gage 0.678 in

Product Description

The VERMONT GAGE 111167800 is a Class ZZ Plus plug gage designed for precise inside-diameter inspection in quality control and metrology applications. Machined from tool steel, this gage measures a nominal diameter of 0.678 inches with a tolerance of 0.0002 inches and a 10 microinch surface finish. It is used to verify that bored, drilled, or reamed holes fall within acceptable dimensional limits. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and calibration professionals use this gage as part of routine go/no-go inspection workflows.

This plug gage is suited for go inspection tasks in manufacturing, toolroom, and quality assurance environments. It is compatible with use alongside set micrometers, verniers, and other measuring devices for instrument qualification and verification. The 0.678-inch diameter and 2.0-inch overall length make it practical for bench use and portable field calibration setups in both production and inspection lab settings.

Key Features

• 10 microinch surface finish for consistent, repeatable contact measurement
• Tool steel construction for durability and wear resistance in regular use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standard for plain plug gages
• Compact 2.0-inch overall length suits bench and portable inspection use

Compatibility

Designed for go inspection use with set micrometers, verniers, and other measuring devices as stated by the manufacturer. Suitable as a Class ZZ Plus plain plug gage for inside-diameter verification in standard toolroom and quality control applications.

Installation Notes

Plug gages are handled and used by quality technicians and calibration professionals — no power tools or mechanical installation is required. Store and handle the gage with clean, dry hands or lint-free gloves to prevent corrosion from skin contact on the tool steel surface. Do not force the gage into a bore; apply light, steady hand pressure only. Clean the gage and store it in its protective case between uses to maintain surface finish and dimensional integrity.
