1/4 x 2 1/2 Heat Treated Steel Standard Dowel Pin separates alignment from clamping so the bolted joint does not have to carry both jobs. Standard Series dowels are intentionally oversize, with the basic diameter 0.0002 in. over nominal so the pin presses into a nominal reamed hole.

For retrofit work, die repair, or maintenance replacement, confirm the reamed hole condition, pin diameter, and length before release to production or repair. For worn or re-reamed holes, 0.001 Oversize Dowel Pins are the repair companion to standard pins used for initial installation.

Cold Headers can help confirm the exact diameter and length before quoting pricing and availability. Review the nominal diameter, measured pin range, recommended hole size, end form, and length before matching this dowel pin to an assembly.
