Difference between wood and sheet metal screws. Wood sheet metal and drywall screws differences uses and head types. Wood screws are numbered from 0 to 20 indicating a diameter from about 1 16 in. While a sheet metal screw can be used to securely fasten wooden pieces a wood screw with a smooth shank portion won t create a tight joint in sheet metal and fully threaded wood screws may hold poorly.

Wood screws are meant to be used on wood while metal screws are meant for metal most commonly sheet metal. Both types of screws are readily available in lengths between 1 4 inch and 3 inches adequate for just about any household fastening job.

The threads on wood screws usually are coarse and deep to help them grab the wood. Machine screws have finer threads than wood screws. I have a lot of black metal screws and the same for silver or other color wood screws.

These screws usually are short and have coarse threads that are designed to grab onto relatively thin sheet metal. The length of wood screws is measured in inches and fractions of inches and ranges from approximately 3 4 inches long to 4 inches. These have a coarser pitch few threads per inch than sheet metal or machine screws and often have an unthreaded shank the threadless shank allows the top piece of wood to be pulled flush against the under piece without getting caught on the threads. It depends on the screw manufacturer.

The sheet metal screws flaunt a straight shank along with a finer threading pattern other than the wooden rivets which are threaded only two thirds of the way up. Pitch refers to the number of threads per inch. The metal rivets feature number of pitches than the wooden ones.
