5/8 x 2 1/4 Pull Dowel Pin (Threaded Dowel Pin) is a hardened, precision-ground dowel pin with an internally tapped hole in one end. The same product may appear on drawings or maintenance notes as a pull dowel, pull-out dowel, tapped dowel, or threaded dowel pin. In die work, the pull feature helps remove individual sections for rework without flipping the die or tearing down the whole assembly.

This size is often reviewed for mold-change tooling, setup fixtures, and locating nests when a standard dowel would be difficult to extract from a blind hole. For corrosion-driven precision locating, compare 18-8 Stainless Steel Standard Dowel Pins instead of bare heat treated steel.

Cold Headers has supplied specialty fasteners since 1962 and helps buyers match exact dowel sizes to drawings and service records. 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.
