do you know what this screw is

Home Depot deck screws came with a square driver bit. Now they stock SPAX that uses a hybrid Phillips/square drive (ie. Quadrex, Pozisquare). Works great, won't cam out like a phillips. It'll either bog your drill down, hit the clutch limiter or worse, take you wrist for a ride. We had to turn in all our corded drills for clutch type battery drills due to wrist injury potential. I had a Makita 2 speed that would throw you it was so torquey.
