Vermont Gage 112311150 Class Zz Plus Plug Gage 11.15mm

Product Description

The VERMONT GAGE 112311150 is a Class ZZ Plus plug gage manufactured from tool steel for dimensional inspection of bored holes and machined features. It is designed to verify that a hole or bore meets minimum acceptable size requirements in a go/no-go inspection workflow. The gage has a nominal diameter of 11.15 mm with a tolerance of 0.005 mm, and a 10 microfinish surface finish on the gaging member. Each unit ships with a Certificate of Accuracy traceable to NIST. Machinists, quality technicians, and tool-room personnel use this gage in production and incoming inspection environments.

This plug gage is suited for go inspection tasks on machined components, castings, and fabricated parts where hole diameter must be verified to close tolerance. It works alongside set micrometers, vernier calipers, and other precision measuring devices for process control and part qualification. The 10 microfinish surface reduces wear and helps maintain calibration integrity over repeated use cycles. It is appropriate for both job-shop and production-floor inspection stations handling metric-dimensioned workpieces.

Key Features

• Class ZZ Plus tolerance class per ASME B89.1 for reliable go inspection
• 11.15 mm nominal diameter with 0.005 mm tolerance
• 10 microfinish surface on gaging member for reduced wear and consistent contact
• Tool steel construction for hardness and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Compatible with standard go/no-go inspection procedures alongside micrometers and verniers

Compatibility

Designed for use in go inspection applications with set micrometers, verniers, and other precision measuring devices per ASME B89.1 standards.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Store the gage in its protective case when not in use and keep it clean and lightly oiled to prevent corrosion. Do not force the gage into an undersized bore, as this will damage the gage and affect calibration. Recalibrate on a scheduled interval consistent with your quality management system requirements.
