Particle board screws were originally designed for use with particle board and MDF, but are now commonly used with all types of wood. These self-tapping screws feature coarse, widely spaced, sharp helical threads that cut into the base material. They often have sharp tips and are available with bugle or countersunk heads, typically with ribs to allow the head to sit flush with the surface once fully inserted. They are frequently used in joinery, furniture construction, and for fastening items to timber.
