Vermont Gage 112310890 Class Zz Plus Plug Gage 10.89mm

Product Description

The VERMONT GAGE 112310890 is a Class ZZ Plus plug gage designed for dimensional inspection of bored holes and machined features. It measures 10.89 mm in diameter with a tolerance of 0.00508 mm, making it a precise go-inspection tool suited for quality control environments. Manufactured from tool steel with a 10 microfinish surface coating, this gage delivers consistent, repeatable results when checking hole size acceptance. The overall length is 2.0000 inches. A Certificate of Accuracy with NIST traceability is included, meeting ASME B89.1 standards. Machinists, toolroom technicians, and quality inspectors use this type of gage in production and inspection workflows.

This plug gage is used in go inspection applications to verify that a bored or drilled hole meets minimum size requirements. It is compatible with standard gage handle systems and works alongside micrometers, verniers, and other measuring devices for complete dimensional verification. Typical use environments include machine shops, manufacturing floors, and inspection labs handling precision-tolerance work at the 10.89 mm nominal diameter. The NIST-traceable certificate supports quality management systems requiring documented calibration records.

Installation Notes

Plug gages are handled and used by quality technicians and toolroom machinists following shop metrology procedures. Store the gage in its protective case when not in use to prevent surface damage. Clean the gage and the workpiece bore before inspection to avoid false readings from chips or coolant residue. Do not force the gage into a bore; apply light, consistent hand pressure only to avoid damage to the gage or workpiece.
