Phillips Square-Driv® Replacement Bits
These replacement bits go with the Phillips Square-Driv® Screws.
The square drive recess means there’s reduced stripping and 33% more steel at the torque point, making them virtually unbreakable. Easily drive them with a standard Phillips head driver or a Phillips Square-Driv® bit that comes in every box. Compatible with ACQ, CCA and CA pressure treated lumber. Imported.
