5/8 x 5/16 Heat Treated Steel Standard Dowel Pin is a standard-series dowel for pressed installation into a properly prepared 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 automation tooling, end-of-arm fixtures, and changeover plates when a drawing calls for standard-series press-fit dowels. For corrosion resistance, compare 18-8 Stainless Steel Standard Dowel Pins rather than treating bare heat treated steel as a corrosion-resistant choice.

Cold Headers has supplied specialty industrial fasteners since 1962 and supports exact-size dowel pin sourcing. Review the nominal diameter, measured pin range, recommended hole size, end form, and length before matching this dowel pin to an assembly.
