1 x 3 1/4 Heat Treated Steel Standard Dowel Pin is a precision ground pin for assemblies that need controlled press-fit location. 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 gauge fixtures, inspection tooling, and check fixtures when a drawing calls for standard-series press-fit dowels. For worn or re-reamed holes, 0.001 Oversize Dowel Pins are the repair companion to standard pins used for initial installation.

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.
