Silicon Bronze Wood Screws
These Silicon Bronze screws have cut threads and the full-bodied diameter shank desired by boatbuilders. Unlike rolled thread screws with their reduced shank--these screws have a shank diameter that is the same size as the outside of the threads. This completely fills the clearance hole normally drilled for the shank thus creating a waterproof seal. These wood screws have a square drive recess to help prevent cam out.

Silicone bronze is what they recommend for boat building. They are quite expensive and the square heads do strip out pretty easily, so pre-drilling is a must. That said. they do what they are supposed to do.

These are the first order for screws from Jamestown and probably my last. These screws are very dull and take a lot of effort to screw in my mahogany.

I've used the square drive SB screws in both boats I've built and find them a great investment. They get pricier as time passes, but always a good investment.

THE SQUARE DRIVE HEAD IS THE ONLY WAY TO GO. Even with square drive these screws won't survive a ham fisted driver. Best to learn some touch on a power driver or get used to throwing away pricey screws. Once mastered, screws are durable and very appropriate for marine environment. I keep an assortment of sizes for a variety of uses.

So much easier to drive these soft screws without stripping the heads as has been my experience with Freerson heads.
