Dowel pins are hardened and precision ground cylindrical pins and are usually used as locating devices.
They are machined to tight tolerances on the diameter usually with an m6 tolerance, meaning they are slightly oversize for an interference fit.
The corresponding holes are usually reamed to allow for a press fit, clearance fit or transition fit.
