Vermont Gage 111159700 Class Zz Plus Plug Gage 0.597 in

Product Description

The VERMONT GAGE 111159700 is a Class ZZ Plus cylindrical plug gage designed for precision go inspection of bored, reamed, and drilled holes. It measures a nominal diameter of 0.597 inches with a tolerance of 0.0002 inches, making it suitable for verifying hole dimensions in close-tolerance machining and quality control applications. The gage is manufactured from tool steel and features a 10 microinch surface finish for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming compliance with ASME B89.1 standards. Machinists, quality technicians, and tool room personnel rely on this type of plug gage for fast, reliable attribute inspection on the shop floor or in the inspection lab.

This plug gage is used in go inspection setups where the technician needs to confirm that a hole falls within the minimum acceptable diameter. It is appropriate for use alongside set micrometers, vernier calipers, and other measuring devices during first-article inspection, in-process checks, or final quality audits. The 0.597-inch diameter and 2.0-inch overall length make it well suited for a range of standard hole sizes in both production and tool room environments. Suitable for residential shop, commercial manufacturing, and aerospace or industrial quality programs where ASME B89.1 compliance is required.

Key Features

• 0.597-inch nominal diameter with 0.0002-inch tolerance for tight attribute inspection
• 10 microinch surface finish ensures accurate, repeatable contact with bore walls
• Tool steel construction provides durability and resistance to wear in production environments
• Includes Certificate of Accuracy with NIST traceability, compliant with ASME B89.1
• 2.0-inch overall length suits a wide range of standard inspection setups

Compatibility

Designed for use as a go plug gage in conjunction with set micrometers, verniers, and other precision measuring devices where 0.597-inch nominal hole inspection is required per ASME B89.1 standards.

Installation Notes

Plug gages are handled and used by quality technicians and machinists familiar with attribute gauging procedures. Clean the gage and the bore thoroughly before inspection to prevent debris from affecting the reading. Never force the gage into a hole; go gages should enter under their own weight or with light hand pressure only. Store the gage in a protective case away from moisture and abrasive contaminants to preserve the calibrated surface finish.
