What is pin gauge

It s a pin shaped gauge manufactured with a specific size and durable
materials to insure certain margin tolerance.
The main purpose is to check and determine the diameter of a small hole,
however, it can also be used for geometric deviation measuring.

Precautions before use

Clean the gauge with benzine or wipe o the anti-rust oil and dirt with
clean cloth before use.
Ensure there is no rust, scratch or burrs.

Precautions when using

When using pin gauge, make sure there is no burrs or rust on the edge face.

After using, clean and apply oil on the gauge. Make sure it s scratch-free
then place in provided case.
For long-term storing, convey an inspection every half-year, apply anti-rust
oil and keep it at a place with small changes in humidity and temperature.
