Vermont Gage 911105800 Class Zz Plus Plug Gage 0.058 in

Product Description

The VERMONT GAGE 911105800 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bored holes and machined features. It measures a nominal diameter of 0.058 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy go inspection work. Constructed from tool steel with a black oxide finish, this gage offers corrosion resistance and durability in shop environments. Each unit ships with a Certificate of Accuracy backed by NIST traceability, meeting ASME B89.1 standards. Machinists, quality control technicians, and metrology professionals use this type of gage as part of standard inspection workflows.

This plug gage is used in go inspection applications to verify that a bored, drilled, or reamed hole meets minimum dimensional requirements. It is also used to set and verify micrometers, verniers, and other measuring devices in calibration routines. At 2.0 inches overall length, it fits comfortably in handheld use for both production floor and inspection room environments. Typical users include CNC machinists, tool room technicians, and quality assurance personnel working to tight dimensional tolerances in aerospace, automotive, and general precision machining applications.

Compatibility

Designed for go inspection of holes and bores at 0.058 inch nominal diameter, and for use in setting micrometers, verniers, and other precision measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages should be handled by qualified inspection or metrology personnel. Clean and inspect the gage and the part feature before use to prevent false readings caused by chips or contamination. Do not force the gage into a bore; excessive insertion force can damage both the gage and the workpiece. Store the gage in its protective case when not in use to maintain calibration integrity.
