1/4 x 2 3/4 0.001 Oversize Dowel Pin is a precision-ground repair dowel for assemblies where accurate location must be recovered after wear. Use this pin after the hole has been corrected for shape and alignment, because the oversize diameter is intended to recover fit, not hide poor geometry.

Repair departments use this family when the drawings still call out the nominal pin size but the fit has opened up. Review the nominal diameter, actual oversize diameter range, length tolerance, end style, material, and ASME series before substituting a standard pin.

For uncommon dowel lengths or exact repair sizes, Cold Headers keeps the catalog focused on the dimensions buyers need to verify. Tension Pins are the related economical option when retention in a drilled hole is enough and precision-ground location is not required.
