Abstract:
A reduced material fastener has a shank cross-section selected to provide a parting line. Having a parting line means that the fastener may be made using two opposing dies, including roller dies, to cold form the cross-section. The cross-sections do not have to be symmetrical with respect to the parting line as long as hypothetical dies can be separated. Typical fasteners include common nails. Cross-sections having parting lines may have fin-like protuberances that result in less material being used for the same overall outline as a round cross-section. A computer aided design methodology and a nail making apparatus are also disclosed.
