1/2 x 4 Pull Dowel Pin (Threaded Dowel Pin) is a pull-out dowel for reamed holes that need later service access. Pull dowel pin is the catalog term; threaded dowel pin and removable dowel pin are common engineering search terms. A standard dowel in a blind hole has no back side for punch-out access, so the tapped end provides the practical removal path.

In scheduled teardown tooling, wear plates, and die shoes, the pull feature supports service without disturbing more of the assembly than necessary. When a worn precision hole needs its fit restored, 0.001 Oversize Dowel Pins are the related repair option.

Cold Headers brings long-running industrial fastener experience to pull dowel pin quoting and cross-checking. Review the diameter range, recommended reamed hole size, length, hardness, and removal feature before matching this pull dowel to a die, mold, or fixture record.
