Outdoor Screws, Part 2
Here is part two of a two-part series on outdoor woodscrews. Last week we took a look at zinc-plated steel screws. This week, a couple more options.

For many years, woodworkers have relied on solid brass woodscrews for exterior applications. They look good in the wood, but the best thing they have going for them is that they don't rust. The down side is that solid brass screws are relatively soft. So they can strip out or easily break, especially when being driven into hardwoods. Pre-drilling is required.

Another alternative to plated steel is stainless steel. Stainless steel is a chromium-alloy steel, and while not as strong as an "ordinary" steel screw, they're much stronger than solid brass.

For maximum rust resistance, there's a woodscrew preferred by boat builders -- silicon bronze. These screws are made from an alloy of copper with silicon included in the mixture for additional corrosion resistance. Silicon bronze screws are stronger than solid brass, but they're not quite as strong as steel screws. However, they're plenty strong for any home outdoor project. And they look great with most woods.

Note: I have received a couple of questions about deck screws. There are lots of interesting things going on in deck screws, and I'll be taking a look at them in a future weekly woodworking tip.
