Usually, the coarse threads are better for plywood than fine threads since they establish stronger hold in it. You can get a faster start for single-step installations this way. Self-drilling design saves you time and energy from pre-drilling. Screws are more suitable for the soft plywood blocks since they can be removed more easily and do not cause splintering. Star drive head design is compatible for easy countersinking. You can use a variety of joinery options for making face frames, including dowels, mortise-and-tenons or even small biscuits, but none are as fast as pocket screws.
