Vermont Gage 111326350 Class Zz Plus Plug Gage 0.2635 in

Product Description

The VERMONT GAGE 111326350 is a Class ZZ Plus plug gage designed for precise hole diameter inspection in machining, toolroom, and quality-control environments. Measuring 0.2635 inches in diameter with a tolerance of 0.0002 inches, this gage delivers the accuracy required for Go inspection of bored, drilled, and reamed holes. Manufactured from tool steel with a 10 microfinish surface, it maintains dimensional integrity under repeated use. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements of ISO-compliant inspection processes. Licensed machinists, toolroom technicians, and quality-control inspectors are the primary users.

This plug gage is suited for use in production inspection lines and toolroom environments where tight tolerances must be verified. It is compatible with Go inspection procedures and can be used to calibrate or verify set micrometers, verniers, and other precision measuring devices. The 2.0-inch overall length provides a balanced grip for single-handed operation. Applicable in any facility where ASME B89.1 dimensional standards are enforced, including aerospace, automotive, and general precision machining shops.

Key Features

• 0.2635-inch measurement diameter with 0.0002-inch tolerance for tight Go inspection work
• 10 microfinish surface finish on tool steel for consistent, wear-resistant gaging contact
• Includes Certificate of Accuracy with NIST traceability for documentation and audit compliance
• Conforms to ASME B89.1 standards for dimensional gages
• 2.0-inch overall length supports ergonomic single-hand use during inspection
• Compatible with set micrometers, verniers, and other precision measuring instruments

Compatibility

Designed for Go inspection of holes and bores, and for use with set micrometers, verniers, and other measuring devices requiring a precision reference standard at 0.2635 inches diameter.

Installation Notes

Plug gages are handled and deployed by machinist or quality-control technicians — no power source or mechanical installation is required. Before use, clean the gage and the workpiece bore with a lint-free cloth to remove chips, oil, and debris that could affect measurement accuracy. Do not force the gage into an undersized bore; forcing will damage the gage surface finish and invalidate calibration. Store in a protective case away from temperature extremes to preserve dimensional stability.
