Some of the best metal to wood fence brackets available on the market include the Simpson Strong-Tie FB24Z, OZCO 50110, and the USP Structural Connectors FPBB44.

A bolo tie.
A pier is a structure built to extend into (usually) tidal waters to allow ships and boats to tie up even at low water. In many cases today they are similar structures built for entertainment purposes.
Ships sometimes tie up at docks or berths in ports, where they can safely moor to load or unload cargo and passengers. They may also tie up at marinas for recreational purposes or at specialized facilities for maintenance and repairs. Additionally, vessels can tie up at offshore mooring buoys or anchorages when port access is restricted or during adverse weather conditions.
Eventual wear and tear (metal stress), as well as rust, will cause a tie rod break.
