  • Patent number: 10871181
    Abstract: In a method for producing a connecting element, in particular a bolt, a zinc anti-friction coating is applied to a blank made of a metallic base material. Subsequently, the coated blank is deformed in a deformation process to a desired final geometry of the bolt. The deformation process may, in particular, be a thread rolling process. The anti-friction coating is applied in particular by way of a zinc diffusion method. The bolt is in particular an engine bolt, specifically a connecting rod bolt. A bolt of this type has a durability as conventional bolts, but at the same time can be mounted repeatedly by virtue of the formation of the special anti-friction coating without the coefficients of friction increasing above permissible limits.
