ABSTRACT:
A pin which has a compressive strength less than the tensile strength of a substrate can be fixed into a hole in the substrate when the substrate is held between a stopping block and a clamp by transporting the pin into the hole with sufficient kinetic energy that the pin is forged into a shape defined by the hole upon impacting the stopping block.
The pin can be retained in the substrate by forging it into a headed and bulged shape defined by recesses in the stopping block and the clamp on either side of the hole.
