Fastening Method And Fastening System

Patent No. EP3612737 (titled "Fastening Method And Fastening System") was filed by Hilti on Apr 18, 2018. The application was issued on Feb 22, 2023.

Patent Summary

A fastening method and system that achieves high holding force in a blind hole by displacing substrate material in the depth direction as the fastener is driven in, resulting in a weld at the peripheral surface. The method involves producing a blind hole with a diameter smaller than the fastener's face diameter, and driving the fastener into the hole while displacing substrate material. The resulting heat causes the fastener to weld to the substrate at the peripheral surface. The system comprises a substrate and a fastener with a shank that displaces substrate material as it is driven into the hole, resulting in a weld at the peripheral surface.
