7/16 x 2 1/4 0.001 Oversize Dowel Pin belongs to the ASME B18.8.2 Oversize Series for replacement locating-pin service. Re-ream the worn hole clean and true; the additional 0.001 in. of pin diameter restores the interference a standard pin can no longer provide.

Tooling plates and die shoes may call for an oversize dowel after repeated disassembly has loosened a standard pin. Review the nominal diameter, actual oversize diameter range, length tolerance, end style, material, and ASME series before substituting a standard pin.

Cold Headers has supplied specialty fasteners since 1962 and helps buyers identify exact-size dowel pins for repair work. Standard series dowel pins are the initial-installation choice; 0.001 oversize dowels are the repair option when the fit has opened up.
