Pull Dowel Pins are hardened cylindrical pins with an internal thread that an extraction tool can be threaded into for removal of the pin.

Both vented and non-vented Pull Dowel Pins are available. A vented Pull Dowel Pin has a small flat spot along the length of the pin which allows air to escape for easier installation into a blind hole. A non-vented Pull Dowel Pin does not have the flat spot and are typically used on through holes.

They are 2 types of thread pins: Inner thread pins and outer thread pins.  

In the norms, the most common pins are;
