Silicon Bronze is probably the bestmetal formarine nails, screws and bolts.

It is an alloy of copper and small amounts of silicon. It is to all intents immune to self-corrosion either in the atmosphere or immersed in seawater.
It is hard and nearly as strong as the so-called marine grades of stainless steel.

WHY Silicon Bronze over 316 Stainless Steel
Stainless Steels require constant exposure to oxygen to maintain a Chromium Oxide film on the surface. This protects the steel and makes it corrosion resistant.
Inserting 316 Stainless Steel fittings through a deck or other tight cavity that does not allow exposure to air and water makes contact you will get crevice corrosion.
That is why the Australian Yachting Federation banned plastic coated wire for life lines on yachts.
Through deck fittings are classics to suffer from crevice corrosion.

BUYER BEWARE
There are some chinese sourced silicon bronze fasteners and nails around.
We do not stock fasteners from China.  
We source our Silicon Bronze fasteners from the USA & New Zealand.

The reason is not being able to guarantee the quality of the materials being used in the manufacturing process.  With silicon bronze the percentages of the alloys used is critical.  
Small percentage changes can change the strength and corrosion resistance of silicon bronze making it unsuitable for marine use.
