5/16 x 1 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.

Gauge fixture recovery benefits from an oversize dowel when repeatable location is more economical than remaking the fixture. 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.
