5/16 x 1 1/4 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. The pin can be withdrawn straight from the tapped end, helping protect the reamed hole and the pin during service.

For die sections, punch retainers, or die maintenance plates, 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.

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.
