Vermont Gage 111115000 Class Zz Plus Plug Gage 0.15 in

Product Description

The VERMONT GAGE 111115000 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of holes and bores at a nominal diameter of 0.15 inches. It carries a tolerance of 0.0002 inches and a 10 microfinish surface finish, meeting ASME B89.1 standards for gage accuracy. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality-controlled environments where traceability documentation is required. Machinists, quality technicians, and tool-room inspectors use this gage to verify hole size on production parts and to calibrate or check go/no-go inspection setups.

This plug gage is intended for go inspection applications on holes or bores sized to 0.15 inches. It is also used as a reference standard when setting micrometers, verniers, and other measuring devices to a known diameter. Typical install scenarios include incoming inspection, in-process quality checks on machined components, and tool-room calibration routines in both job-shop and production manufacturing environments. The overall length of 2.0 inches provides a comfortable grip for single-hand use during inspection passes.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go inspection
• 10 microfinish surface finish minimizes wear on the gage and the part being inspected
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documented quality systems
• Tool steel construction for durability and resistance to wear in production environments
• 2.0 inch overall length suited for manual single-hand inspection use

Compatibility

Designed for go inspection of holes and bores with a nominal diameter of 0.15 inches, and for use as a reference standard when setting micrometers, verniers, and other measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power source or utility shutoff is required. Store the gage in its protective case when not in use to prevent nicks and corrosion that would affect accuracy. Handle with clean, dry hands or inspection gloves to avoid transferring oils that can affect the 10 microfinish surface. Verify the gage is at thermal equilibrium with the work environment before taking measurements, as temperature variation can affect readings at this tolerance class.
