Vermont Gage 111173000 Class Zz Plus Plug Gage 0.73 in

Product Description

The VERMONT GAGE 111173000 is a Class ZZ Plus plug gage designed for precise go inspection of bored, drilled, and reamed holes. Manufactured from tool steel, this plug gage measures a nominal diameter of 0.73 inches with a tight tolerance of 0.0002 inches, making it suitable for applications where accurate dimensional verification is required. The working surface carries a 10 microfinish for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality and traceability requirements in production and inspection environments. Machinists, quality technicians, and metrology professionals use this tool as part of standard dimensional inspection routines.

This plug gage is intended for go inspection of workpiece features at 0.73 inches diameter. It is well suited for use alongside set micrometers, verniers, and other precision measuring devices in manufacturing, toolroom, and quality control settings. Both job-shop and production-floor environments rely on Class ZZ Plus gages when conformance to ASME B89.1 standards is required. The overall length of 2.0 inches makes it easy to handle for single-hand inspection operations on typical machined parts.

Key Features

• Tool steel construction for durability and wear resistance in repeated use
• 10 microfinish working surface for consistent, repeatable contact with the workpiece
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Meets ASME B89.1 dimensional gage standards
• Compact 2.0 inch overall length for easy single-hand use

Compatibility

Designed for go inspection of 0.73 inch diameter features and for use with set micrometers, verniers, and other precision measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by machinists, quality technicians, and inspection personnel — no installation in the traditional sense applies. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the workpiece feature before inspection to remove chips, coolant, and debris that could affect readings. Never force a plug gage into a feature; if the gage does not pass freely under its own weight, the hole is undersized and should be re-inspected with proper hand gauging technique.
