Vermont Gage 111331450 Class Zz Plus Plug Gage 0.3145 in

Product Description

The VERMONT GAGE 111331450 is a Class ZZ Plus plug gage used to verify bore and hole dimensions to a tight tolerance during go inspection procedures. Machined from tool steel to a 10 microfinish surface quality, it measures 0.3145 inches in diameter with a tolerance of 0.0002 inches. The gage is supplied with a Certificate of Accuracy with NIST traceability, meeting ASME B89.1 standards. At 2.0 inches overall length, it fits standard gage handle setups. Machinists, quality technicians, and metrology professionals use this tool to confirm dimensional conformance on production and inspection floors.

This plug gage is suited for go inspection of holes and bores in both production and quality-control environments. It is also used to set and verify micrometers, verniers, and other measuring devices where a traceable reference standard is required. The 0.3145-inch diameter makes it appropriate for precision work in light manufacturing, tool and die, and general machining applications where tight dimensional control is critical.

Key Features

• 10 microfinish surface finish for accurate, repeatable contact
• Tool steel construction for durability and wear resistance
• Meets ASME B89.1 standards for dimensional gaging
• Includes Certificate of Accuracy with NIST traceability
• 2.0 inches overall length compatible with standard gage handle setups

Compatibility

Designed as an OEM-style replacement and reference standard for use with standard plug gage handles and holders suited to the 0.3145-inch diameter class; also compatible as a setting reference for micrometers, verniers, and other measuring devices as noted in the product specifications.

Installation Notes

Plug gages should be handled by metrology or quality personnel following shop calibration procedures. Store in a clean, dry environment away from chips and coolant to preserve the microfinish surface. Always allow the gage and workpiece to reach thermal equilibrium before measuring to avoid temperature-induced dimensional error. Inspect the gage periodically for wear per your facility calibration schedule in accordance with ASME B89.1 guidelines.
