Vermont Gage 912100920 Class Zz Plus Plug Gage 0.92 Mm

Product Description

The VERMONT GAGE 912100920 is a Class ZZ Plus plug gage designed for precision hole inspection in tool rooms, quality labs, and production environments. Built from tool steel with a black oxide finish, this gage checks bore diameters at 0.92 mm with a tolerance of 0.00508 mm, making it suitable for Go inspection applications. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets ASME B89.1 standards. Licensed metrology technicians and quality inspectors are the primary users of this instrument.

This plug gage is used in precision measurement and quality control operations across manufacturing and machining environments. It is suited for Go inspection of small-diameter bores and holes, and can be used alongside micrometers, verniers, and other measuring devices for comparative or calibration tasks. Its compact form factor makes it practical for bench-top inspection stations as well as in-line production checks where tight diameter tolerances must be verified.

Key Features

• Class ZZ Plus tolerance rating for Go inspection of 0.92 mm diameter bores
• Tolerance of 0.00508 mm for high-precision dimensional verification
• Tool steel construction with black oxide finish for durability and corrosion resistance
• Overall length of 2.0000 inches for standard handle compatibility
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 standards for plain plug gages

Compatibility

Designed for use with go inspection setups, micrometers, verniers, and other precision measuring devices where 0.92 mm bore diameter verification is required.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists; no power shutoff is required for use. Keep the gage clean and lightly oiled when stored to prevent corrosion on the tool steel surface. Handle with care to avoid contact with abrasive surfaces that could alter the gage diameter. Calibration and use should follow ASME B89.1 guidelines and your facility's inspection procedures.
