High-quality 4-gauge silicon bronze wood screws in a variety of lengths.  These silicon bronze screws have a slotted countersunk (CSK) head and are ideal for use as boat building screws.

Even buried in the wooden structure of a boat, silicon bronze screws will not corrode - unlike stainless steel screws which will corrode when shielded from oxygen and unable to build a protective oxide layer.

We also recommend silicon bronze screws (or silicon bronze machine screws for high-load situations) for fastening our bronze deck hardware.
