1/4 x 3 1/2 Pull Dowel Pin (Threaded Dowel Pin) is selected where die maintenance or fixture teardown requires pulling the pin straight out. The internal tapped end is why this family is often searched as a pull-out dowel or threaded removal dowel. In die work, the pull feature helps remove individual sections for rework without flipping the die or tearing down the whole assembly.

For automation plates, indexing fixtures, or machine nests, check the reamed hole, pull access, and whether the tapped end can be reached after assembly. When a worn precision hole needs its fit restored, 0.001 Oversize Dowel Pins are the related repair option.

Since 1962, Cold Headers has helped industrial buyers locate specialty pin and socket-product configurations. 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.
