#8 Silicon Bronze Frearson Flat Head wood screws appear similar to the Phillips head but the Frearson has a more pointed 75° V shape. The Frearson tool recess is a perfect cross which minimizes cam out, unlike the Phillips head, which is designed to cam out.
Traditional boatbuilders love these Silicon Bronze wood screws because they have cut threads and the full-bodied diameter shank. 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.

Silicon Bronze is the traditional choice for marine construction. It is corrosion resistant, helps prevent rot around the screw holes when used under water, and is relatively strong. Although stronger than Solid Brass, Silicon Bronze screws are not as strong as Stainless Steel. They require a carefully sized pilot hole to avoid breakage. We recommend drilling twice (once for the root and once for the shank) as well as using fastener lubricant to avoid breakage.

Silicon Bronze is the way to go!
I am very happy with these wood screws that I ordered. I am assembling the cockpit sole framing in my Haven 12 1/2. The white oak is very dense and very strong. I must carefully drill the screw holes with a countersink bit. Previous screws, stainless and brass have routinely snapped off inside the hole. These silicon bronze screws are very strong. It pays to spend the money on quality!

Good, But ask for a box
As of May, 2019, these were shipped in a little plastic bag, not the box like in my previous orders. I have trouble keeping track of all the different size/style/material screws I keep on hand, and at about $30 per hundred, the cost adds up quickly - I cannot imagine how to keep things organized in little, open plastic bags. If you want these in a box, you now have to request a box.
fast, easy and right.
Product was exactly as advertised. Jamestown Distributors web site was very easy to use. The screws and bits were delivered very fast. Very happy with everything.
