Generally a sheet metal screw will have much less bite.

Sheet Metal Screws / Wood Screws / Drywall Screws / Particle Board Screws: Few people know the difference. Here's a short summary. As with all rules, there may be exceptions.
A sheet metal screw is hardened, fully threaded to at least 3 inches, and has a straight shank. They usually have single lead symmetrical threads, though double lead threads are common in some industries. The thread pitch is finer than a wood screw. Most people now use sheet metal screws instead of wood screws -- this is the most common kind of screw used in wood, despite the misleading name.
A wood screw is soft, fully threaded when under one inch in length and threaded approximately 2/3 of the screw length when over one inch in length, and has a tapered shank. They always have single-lead coarse symmetrical threads.
