5/16 x 2 1/4 Heat Treated Steel Standard Dowel Pin is a standard-series dowel for pressed installation into a properly prepared nominal reamed hole. A correctly sized reamed hole lets the dowel become the alignment reference, leaving screws and bolts to provide clamp force.

This size is often reviewed for indexing stops, locator blocks, and gauging hardware when a drawing calls for standard-series press-fit dowels. Alloy Steel Socket Head Cap Screws and Stripper Bolts are natural clamping and guiding partners around a dowel-located joint.

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.
