5/8 x 2 1/4 Heat Treated Steel Standard Dowel Pin is used when mating parts need repeatable location instead of relying on bolts for alignment. For example, this nominal size measures above nominal; the pin is made big so the fit is made right.

This size is often reviewed for jigs and fixtures, locating nests, and drill fixtures when a drawing calls for standard-series press-fit dowels. Bare heat treated steel should be kept oiled in storage and service planning when the environment may promote oxidation.

Since 1962, Cold Headers has helped buyers match specialty fasteners to drawings, repair records, and production requirements. Review the nominal diameter, measured pin range, recommended hole size, end form, and length before matching this dowel pin to an assembly.
