Vermont Gage 111305750 Class Zz Plus Plug Gage 0.0575 in

Product Description

The VERMONT GAGE 111305750 is a Class ZZ Plus plug gage machined from tool steel for precise dimensional inspection of small-diameter bores and holes. Designed for Go inspection, this gage checks whether a feature falls within the acceptable size limit. It measures a nominal diameter of 0.0575 inches with a tolerance of 0.0002 inches, and features a 10 microfinish surface for consistent, repeatable contact. Each unit ships with a Certificate of Accuracy carrying NIST traceability, satisfying most quality-system documentation requirements. Machinists, toolmakers, and quality technicians use this gage in production and inspection environments where precise go/no-go verification is required.

This plug gage is suited for inspecting small bores in precision machined components across manufacturing, aerospace, automotive, and general metalworking applications. It is also used as a reference standard for setting micrometers, verniers, and other measuring devices. The overall length of 2.0 inches makes it compatible with standard gage handle systems. It is appropriate for both shop-floor and metrology lab use where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus accuracy with 0.0002 inch tolerance for precise bore verification
• 10 microfinish surface finish for consistent, low-friction contact during inspection
• Tool steel construction for durability and wear resistance in production environments
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Meets ASME B89.1 dimensional standard
• Compatible with standard gage handles; overall length of 2.0 inches

Compatibility

Designed for Go inspection use and as a setting reference for micrometers, verniers, and other measuring devices. Fits standard plug gage handle systems accepting this diameter range.

Installation Notes

Plug gages are handled and used by machinists and quality technicians; no power source or lockout procedure is required. Keep the gage clean and lightly oiled when not in use to prevent corrosion and wear. Do not force the gage into a bore; apply only light, consistent hand pressure to avoid damage to the gage or the workpiece. Store in the provided case or a clean, dry environment to maintain calibration integrity.
