Vermont Gage 111309550 Class Zz Plus Plug Gage 0.0955 in

Product Description

The VERMONT GAGE 111309550 is a Class ZZ Plus plug gage designed for precise go inspection of bored holes, drilled holes, and other internal features requiring tight dimensional verification. Machined from tool steel, this gage measures a nominal diameter of 0.0955 inches with a tolerance of 0.0002 inches, conforming to ASME B89.1 standards. The 10 microfinish surface ensures consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for controlled quality environments. Machinists, quality control technicians, and tool-room personnel are the primary users.

This plug gage is used in machine shops, manufacturing facilities, and quality inspection stations where small-diameter hole acceptance or rejection decisions must be made quickly and accurately. The 0.0955-inch diameter makes it appropriate for precision close-tolerance work in metalworking and general manufacturing applications. It also functions as a calibration reference for setting micrometers, verniers, and other measuring devices to a known standard diameter.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• 10 microfinish surface for consistent, low-friction gaging contact
• Tool steel construction for durability and wear resistance
• Conforms to ASME B89.1 dimensional gaging standards
• Includes Certificate of Accuracy with NIST traceability
• Suitable for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of internal features at 0.0955 inches nominal diameter. Also used to set and verify micrometers, verniers, and other measuring devices requiring a calibrated reference standard at this diameter.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Allow the gage and workpiece to reach the same ambient temperature before inspection to avoid thermal expansion errors, particularly important at tight tolerances. Store in the provided case or a protected environment away from abrasive materials.
