1/2 x 1 1/4 Heat Treated Steel Standard Dowel Pin is used when mating parts need repeatable location instead of relying on bolts for alignment. 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 spare-pin maintenance, toolroom repairs, and production fixtures 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.
