5/16 x 3 1/2 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. A standard dowel in a blind hole has no back side for punch-out access, so the tapped end provides the practical removal path.

Typical applications include die-maintenance spares, press-room repairs, and service kits, where accurate location and later service access both matter. Where economical retention in a drilled hole is enough, Tension Pins may be the better product family than a ground dowel.

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.
