5/16 x 4 1/2 Heat Treated Steel Standard Dowel Pin is a bread-and-butter die and fixture component for repeatable part registration. Standard Series dowels are intentionally oversize, with the basic diameter 0.0002 in. over nominal so the pin presses into a nominal reamed hole.
In machine frame alignment, mounting plates, and machined bases, the hardened ground pin helps repeat location through service, teardown, and rebuild cycles. For worn or re-reamed holes, 0.001 Oversize Dowel Pins are the repair companion to standard pins used for initial installation.
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.
