How do I select the correct screw and use it properly?

Illustrated are the six types of common screws. These screws can be divided into two basic types: slot-head screws and Phillips-head screws. Both types of screws are available with flat, round, and oval heads.

Illustrated are how these three different types of common heads look when driven into the wood. The oval-head screw extends above the surface in a slight oval. The round-head screw protrudes above the surface in a half-circle. The flat-head screw is flush with the surface.

Type basic types of screwdrivers are needed for driving the different types of screws. The regular slotted screw has a slot in the head, while the Phillips-head screw has a cross slot. Always use the proper screwdriver for the screw you are using.

Use the screw selection chart for selecting the correct size and length of screw for any job (see above). This chart is designed for flat-head screws but can be used for any type. The column on the right shows the size of the pilot hole to be drilled for starting the screw.
