If you are always working with screws, get yourself at least one of these types of screwdrivers. Its flat screw head cannot be used on sheet metal cross head screws. They are best for application in heavy gauge sheet metal. The sheet metal screws are self-tapping, meaning they do not need pre-drilled holes into the source before inserting them. Note that tapped holes are required before a machine screw such as a hex head screw is inserted. These screws are used for applications in various materials but not on metals because they strictly stay in place once screwed on. Steel is the most common material used for the manufacture of screws. These screws are typically sturdier and stronger than wooden screws because they are made of steel.

Therefore, you need a specialized screw that would be effective in a head wood screw drill. Generally, wood expands and shrinks depending on the surrounding temperature. These are designed for connecting items such as metals to wooden bases. Wood screws are measured the same way as other screws: “The length of a headed fastener is defined as the distance between the intersection of the largest diameter of the head and the bearing surface and the extreme.” Screws less than 1″ are measured in 1/8″ increments screws 1″ to 3″ are measured in 1/4″ increments and screws longer than 3″ are measured in 1/2″ increments. Lengths range from 1/4″ to 6″ the longest typically found is 5″ or so, and larger screw sizes are available in the longer lengths. The number size has no bearing on any measurement. Sizes ranging from #2 to #14 are widely available.

The diameter of wood screws ranges from #0 to #24 the larger the number, the larger the size, and #0 is the smallest screw size.
