Vermont Gage 112311570 Class Zz Plus Plug Gage 11.57 Mm

Product Description

The VERMONT GAGE 112311570 is a Class ZZ Plus plug gage designed for precision dimensional inspection of bored holes, drilled passages, and machined features. Manufactured from tool steel with a 10 microfinish surface coating, this gage delivers a diameter of 11.57 mm with a tolerance of 0.00508 mm, making it suitable for go inspection tasks where tight dimensional control is required. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming that the gage meets the stated tolerance at time of manufacture. Machinists, quality technicians, and tool-room personnel use plug gages like this one as a fast, reliable method for verifying hole size without the setup time required by variable measuring instruments.

This plug gage is used in manufacturing inspection, machine shop quality control, and metrology lab environments. It is appropriate for go inspection routines and is also used to set and verify micrometers, verniers, and other measuring devices. The overall length of 2.0000 inches makes it compatible with standard gage handle systems. It is suited for both production-floor spot checks and controlled metrology environments where ASME B89.1 compliance is required.

Compatibility

Designed for use with standard plug gage handles and suitable for go inspection of 11.57 mm diameter features. Also used to set and verify micrometers, verniers, and other measuring devices per the manufacturer application data.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following standard metrology practices. Store the gage in its protective case when not in use to prevent surface damage to the lapped diameter. Clean the gage and the part being inspected before use to prevent debris from affecting measurement accuracy. Do not force the gage into an undersized hole, as this will damage the gage surface and invalidate the calibration.
