3/4 x 3 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 mold repair, guide plates, and tooling inserts 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.
