Although this is some times called a wood tapping screw it is basically a sheet metal design.
Difference between sheet metal screws and wood screws.
Drywall screws can cost between two cents and eight cents per screw depending on the quality brand length and diameter.
A wood screw has threads along about two thirds of its length and costs a little less.
Wood screws can range from eight to 18 cents depending mainly on length and material.
