1/2 x 1 1/4 Pull Dowel Pin (Threaded Dowel Pin) is used when a blind-hole dowel must locate accurately and still come back out for service. The same product may appear on drawings or maintenance notes as a pull dowel, pull-out dowel, tapped dowel, or threaded dowel pin. The pin can be withdrawn straight from the tapped end, helping protect the reamed hole and the pin during service.

In automation plates, indexing fixtures, and machine nests, the pull feature supports service without disturbing more of the assembly than necessary. For published shear ratings, see solid Heat Treated Steel Standard Dowel Pins rather than transferring values to tapped pull dowels.

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.
