5/16 x 2 1/4 Pull Dowel Pin (Threaded Dowel Pin) is a removable dowel pin for assemblies that cannot be punched out from the far side. Buyers may also call this part a pull-out dowel, threaded dowel pin, tapped dowel pin, or removable dowel pin. Otherwise, it performs the locating job of a standard dowel pin: a ground exterior in a reamed hole for repeatable positioning.
For scheduled teardown tooling, wear plates, or die shoes, check the reamed hole, pull access, and whether the tapped end can be reached after assembly. For corrosion-driven precision locating, compare 18-8 Stainless Steel Standard Dowel Pins instead of bare heat treated steel.
For die shops, distributors, and OEM sourcing, Cold Headers can help confirm the diameter, length, and removable dowel style. 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.
