7/16 x 3 1/2 0.001 Oversize Dowel Pin is specified when the important feature is the extra 0.001 in. over nominal diameter. Selection should start with the nominal dowel diameter and required length, then confirm that a +0.001 in. replacement pin is the right repair choice.

Die maintenance programs often pair standard pins for initial builds with oversize pins for later repair work. Review the nominal diameter, actual oversize diameter range, length tolerance, end style, material, and ASME series before substituting a standard pin.

Since 1962, Cold Headers has helped maintenance and production teams locate specialty pins for repair and replacement needs. Pull Dowel Pins are the tapped-end option for blind-hole removal and are often reviewed when a trapped pin must be extracted.
