5/16 x 2 1/2 Pull Dowel Pin (Threaded Dowel Pin) keeps the standard dowel locating function while adding a threaded extraction feature. The same product may appear on drawings or maintenance notes as a pull dowel, pull-out dowel, tapped dowel, or threaded dowel pin. Otherwise, it performs the locating job of a standard dowel pin: a ground exterior in a reamed hole for repeatable positioning.

This size is often reviewed for gauge fixtures, check fixtures, and precision locating plates when a standard dowel would be difficult to extract from a blind hole. Where economical retention in a drilled hole is enough, Tension Pins may be the better product family than a ground dowel.

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.
