Vermont Gage 911115600 Class Zz Plus Plug Gage 0.156 in

Product Description

The VERMONT GAGE 911115600 is a Class ZZ Plus plug gage designed to inspect hole diameters to a tolerance of 0.0002 inches. Built from tool steel with a black oxide finish, this gage delivers reliable dimensional verification for go inspection work. At 0.156 inches in diameter and 2.0 inches in overall length, it is a compact, single-end gage suitable for high-repetition inspection tasks. Each unit ships with a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. Machinists, quality control technicians, and tool room personnel use this gage as part of routine dimensional inspection workflows.

This plug gage is used in production and tool room environments where precise hole diameter verification is required. It is suited for inspecting bores machined to 0.156 inches nominal diameter. The gage is also appropriate for use alongside set micrometers, verniers, and other measuring devices that require a traceable reference standard. Applications span general manufacturing, aerospace, automotive, and any shop environment operating under ASME B89.1 dimensional inspection requirements.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for accurate go inspection
• Tool steel construction for durability in production environments
• Black oxide finish resists corrosion and reduces glare during use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• Compact 2.0-inch overall length for easy handling in tight inspection setups

Compatibility

Designed for go inspection of 0.156-inch nominal diameter bores. Compatible for use with set micrometers, verniers, and other measuring devices requiring a traceable plug gage reference.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists; no power source or mechanical installation is required. Store the gage in its protective case when not in use to prevent damage to the gage surface. Clean the gage and the bore being inspected before use to avoid false readings caused by debris or cutting fluid. Do not force the gage into a bore — apply light, consistent hand pressure only.
