5/16 x 5 Heat Treated Steel Standard Dowel Pin is specified when a standard dowel pin must seat firmly in a nominal reamed hole. Standard Series dowels are intentionally oversize, with the basic diameter 0.0002 in. over nominal so the pin presses into a nominal reamed hole.

This size is often reviewed for indexing plates, locating plates, and assembly tooling when a drawing calls for standard-series press-fit dowels. Pull Dowel Pins add a tapped end for removal from blind holes when the die or fixture cannot be flipped.

Cold Headers helps toolrooms, maintenance teams, and industrial distributors locate hard-to-find dowel pin sizes. Review the nominal diameter, measured pin range, recommended hole size, end form, and length before matching this dowel pin to an assembly.
