1/4 x 4 Pull Dowel Pin (Threaded Dowel Pin) is a hardened, precision-ground dowel pin with an internally tapped hole in one end. The internal tapped end is why this family is often searched as a pull-out dowel or threaded removal dowel. 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 fixture subplates, replaceable stations, and workholding tools when a standard dowel would be difficult to extract from a blind hole. When a worn precision hole needs its fit restored, 0.001 Oversize Dowel Pins are the related repair option.

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.
