Vermont Gage 111335050 Class Zz Plus Plug Gage 0.3505 in

Product Description

The VERMONT GAGE 111335050 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bores and holes with a nominal diameter of 0.3505 inches. Manufactured from tool steel, this gage delivers a tolerance of 0.0002 inches and a 10 microfinish surface, making it suitable for accurate go inspection work. It ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Overall length is 2.0 inches, providing a manageable handle and consistent depth of engagement. Machinists, quality control technicians, and tool room professionals use this gage to verify that machined bores fall within specified dimensional limits.

This plug gage is intended for go inspection applications in precision machining and quality assurance environments. It is also suited for setting and verifying micrometers, verniers, and other measuring devices where a certified reference diameter is required. Typical use cases include production floor inspection, incoming material verification, and calibration support in both job shop and high-volume manufacturing settings. The Class ZZ Plus classification indicates tighter tolerance control than standard Class ZZ, making it appropriate for applications demanding higher accuracy in bore verification.

Key Features

• Nominal measurement diameter of 0.3505 inches for precise bore inspection
• Tolerance of 0.0002 inches conforming to Class ZZ Plus classification
• 10 microfinish surface for consistent, low-friction gaging contact
• Tool steel construction for durability and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional gage standards

Compatibility

Designed as a go plug gage reference standard for use with micrometers, verniers, and other precision measuring devices requiring a certified bore reference at 0.3505 inches diameter.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists — no permanent installation is required. Store the gage in its protective case when not in use to prevent nicks, corrosion, or dimensional changes. Clean the gage and the bore being measured before use to ensure accurate readings and to protect the 10 microfinish surface. Recalibrate or re-certify periodically per your facility quality management procedures and applicable ASME standards.
