Extractable Dowel Pins

Extractable Dowel Pins are precision ground to narrow limits to permit accurate fitting and are traditionally used to hold parts together in a fixed alignment, relying on the tightness of fit to stay in place. Extractable dowel pins have an internal thread which is used to help extract the pin after installation.

There are three factors that determine the size of hole needed; the tolerance on the dowel itself, the tightness of fit required (interference, transition or clearance) and the hardness of the components into which the dowel is fitted.
