Vermont Gage 111173400 Class Zz Plus Plug Gage 0.734 in

Product Description

The VERMONT GAGE 111173400 is a Class ZZ Plus plug gage designed for precise go inspection of bored holes, machined features, and other critical inside dimensions. Manufactured from tool steel with a 10 microinch surface finish, this gage holds a diameter of 0.734 inches with a tolerance of 0.0002 inches. At 2.0 inches in overall length, it is sized for convenient single-handed use on the shop floor or at an inspection station. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying most quality-system documentation requirements. It is built and dimensionally verified to ASME B89.1 standards.

This plug gage is used in manufacturing and machine shop environments where inside-diameter conformance must be verified quickly and reliably. Typical applications include go inspection checks on drilled, reamed, or bored features, as well as setting and verifying micrometers, vernier calipers, bore gages, and similar measuring instruments. It is appropriate for both production-floor inspection and quality-lab use, and is commonly handled by machinists, toolmakers, CMM operators, and quality control technicians.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inches dimensional tolerance for high-accuracy go inspection
• 10 microinch surface finish for consistent, reliable contact measurement
• Tool steel construction for durability and wear resistance in production environments
• Conforms to ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability to support ISO and AS quality programs
• Compact 2.0 inch overall length suits both bench inspection and in-process floor checks

Compatibility

Designed for go inspection of inside diameters at 0.734 inches, and for setting micrometers, verniers, bore gages, and other measuring devices requiring a reference of that diameter.

Installation Notes

Plug gages require no permanent installation but should be handled and stored carefully to prevent nicking or corrosion of the gage surface. Clean the gage and the part feature before each use to avoid false readings caused by chips or coolant residue. Apply light gage oil when storing to protect the tool steel from corrosion. Inspection personnel should follow shop calibration schedules and return the gage for recertification at intervals consistent with frequency of use and applicable quality-system requirements.
