Vermont Gage 111333850 Class Zz Plus Plug Gage 0.3385 in

Product Description

The VERMONT GAGE 111333850 is a Class ZZ Plus plug gage designed for precision dimensional inspection in tool rooms, quality labs, and production environments. It measures bore diameters at 0.3385 inches with a tolerance of 0.0002 inches, making it suitable for go inspection applications where tight dimensional control is required. The gage is machined from tool steel and features a 10 microfinish surface, which supports accurate, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting documentation requirements for ISO-compliant inspection programs. Machinists, quality technicians, and tool room personnel are the primary users of this gage.

This plug gage is used in go inspection of bored holes, drilled passages, and machined features where the nominal diameter is 0.3385 inches. It is also suitable for setting and verifying micrometers, verniers, and other measuring devices that require a known reference standard. The application range covers general metalworking, precision machining, and any manufacturing process that demands verification of minimum acceptable bore size. The 2.0-inch overall length provides a comfortable working grip across standard bench and in-line inspection tasks.

Key Features

• Class ZZ Plus tolerance standard per ASME B89.1 for reliable go inspection
• 0.3385-inch measurement diameter with 0.0002-inch tolerance
• 10 microfinish surface for accurate, low-wear contact with bore surfaces
• Tool steel construction for hardness and dimensional stability
• Certificate of Accuracy included with NIST traceability for documentation and audit support
• 2.0-inch overall length for comfortable single-hand use during inspection

Compatibility

Designed for go inspection of features with a 0.3385-inch nominal bore diameter. Also suitable for setting and calibrating micrometers, verniers, and other measuring devices that accept a precision reference plug at this diameter.

Installation Notes

This gage is a hand-held inspection tool and does not require permanent installation. Store the gage in its protective case when not in use to prevent nicks and surface damage that could affect accuracy. Clean bore surfaces and gage surfaces before use to avoid false readings caused by debris or cutting fluid. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.
