Vermont Gage 111134200 Class Zz Plus Plug Gage 0.342 in

Product Description

The VERMONT GAGE 111134200 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes, drilled passages, and machined features. Manufactured from tool steel, this gage measures a nominal diameter of 0.342 inches with a tolerance of 0.0002 inches, meeting ASME B89.1 standards. The working surfaces carry a 10 microfinish rating, ensuring consistent contact and repeatable readings. A Certificate of Accuracy with NIST traceability is included with each unit. Machinists, quality technicians, and tool-room inspectors use this type of gage as part of go/no-go inspection routines and for verifying the calibration of micrometers, verniers, and other precision measuring devices.

This plug gage is suited for use in manufacturing inspection, job shop quality control, and metrology lab environments where accurate bore verification is required. It is appropriate for both production-line go inspection checks and bench-level calibration support. The 2.0-inch overall length provides adequate reach for most standard bore-depth applications. ASME B89.1 compliance makes this gage acceptable for use in inspection processes governed by common quality system standards such as ISO 9001 and AS9100 shop environments.

Key Features

• 0.342-inch nominal diameter with 0.0002-inch Class ZZ Plus tolerance
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish working surfaces for consistent, repeatable contact
• ASME B89.1 compliant
• Includes Certificate of Accuracy with NIST traceability
• 2.0-inch overall length suitable for standard bore-depth applications

Compatibility

Designed for go inspection of features at 0.342 inches nominal diameter and for use as a reference standard with set micrometers, verniers, and other precision measuring devices requiring a traceable gauge reference.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists; no power source or lockout procedure is required. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Do not force the gage into an undersize bore, as this can damage the gage and the workpiece. Store in a protective case or on a clean surface away from abrasive debris to preserve the microfinish and dimensional integrity.
