Joggle
The act of joining wood or stone with a metal staple is sometimes called joggling. Thus, the staple is called a joggle.
Holes are carefully drilled or chiselled at a slight angle to accept the joggle which is hammered-in under slight tension; this pulls the joint together. Molten lead is then ladled into any gaps to seal the hole to prevent corrosion and lock everything in place. Excess lead is chiselled away when cool.
Seen here is a fireplace lintel that has previously cracked and then joggled.
