Vermont Gage 111160500 Class Zz Plus Plug Gage 0.605 in

Product Description

The VERMONT GAGE 111160500 is a Class ZZ Plus plug gage designed for precision bore and hole diameter inspection. Built from tool steel with a 10 microinch surface finish, it measures a nominal diameter of 0.605 inches with a tolerance of 0.0002 inches. This gage is used to verify that a manufactured hole meets its specified dimensional limits. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming that the gage itself meets the stated tolerance class. Machinists, quality control technicians, and tool room personnel are the primary users.

This plug gage is suited for Go inspection applications on production floors and in quality labs. It is also appropriate for setting and verifying micrometers, verniers, and other comparative measuring devices. The 0.605-inch measurement diameter and 2.0-inch overall length make it practical for standard bore inspection tasks in both job shop and production environments. Conformance to ASME B89.1 makes it appropriate for use in quality programs that require traceable inspection tooling.

Key Features

• Class ZZ Plus tolerance class with 0.0002-inch tolerance for high-accuracy Go inspection
• 10 microinch surface finish for consistent, repeatable gage contact
• Tool steel construction for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional gage standards
• 2.0-inch overall length suitable for standard bore access

Compatibility

Designed for Go inspection of bores and holes at a nominal diameter of 0.605 inches. Also suitable for setting micrometers, verniers, and other comparative measuring instruments requiring a traceable reference standard.

Installation Notes

Plug gages are handled and used by machinists and quality technicians — no installation in the traditional sense applies. Store the gage in its protective case and keep it free of chips, coolant, and contaminants that could affect the measurement surface. Never force the gage into a bore; a Go gage should pass under its own weight when the hole is within tolerance. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.
