Vermont Gage 111134500 Class Zz Plus Plug Gage 0.345 in

Product Description

The VERMONT GAGE 111134500 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore and hole diameters to tight dimensional tolerances. It measures a nominal diameter of 0.345 inches with a tolerance of 0.0002 inches and delivers a 10 microfinish surface on the gage member. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming compliance with ASME B89.1 standards. Machinists, quality technicians, and dimensional inspection personnel use this gage as part of go/no-go inspection routines or to calibrate and verify setting of micrometers, verniers, and other precision measuring devices.

This plug gage is suited for go inspection applications in production and quality control environments, both in job shops and manufacturing facilities. At 2.0 inches overall length, it fits standard gage handle holders and works alongside setting fixtures and bench-top inspection setups. It is appropriate wherever a traceable, repeatable reference standard is needed to qualify hole acceptance or to set a measuring instrument to a known diameter.

Key Features

• Nominal measurement diameter of 0.345 inches with 0.0002 inches tolerance
• 10 microfinish surface for accurate, low-wear contact with the workpiece
• Tool steel construction for durability in production inspection use
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• 2.0 inches overall length compatible with standard gage handles

Compatibility

Designed as an OEM-style precision reference standard for go inspection of 0.345-inch nominal bores, and for setting micrometers, verniers, and other calibrated measuring devices requiring a traceable plug gage reference.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power tools or utility shutoffs are required. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage member into a bore; excessive force will damage the finish and invalidate the measurement. Store in the supplied case or a protected location away from surfaces that could cause impact damage or contamination.
