The #14 by 5" screw with.54" truss head work great for joining treated lumber in fences, pergolas or any structural application. It comes with a “knurl“, or multiple small protrusions at the top of the threads. The Modified truss head screw (1/2" head diameter) has better compression that forces deep, wide, sharp screw threads. The wide and sharp screw threads provide maximum holding power.

It provides twice the torque of phillips or square drive screw heads. They secured the caster plates very well, needed no pre-drilling prior to insertion, and the Torx washer-head on the screw engaged the caster mounting plates perfectly. It is great for outdoor wood projects.

Why We Like This:
  • Heat treated steel, triple coated, and acq treated lumber compatible
  • Hour corrosion resistance in both acq and salt spray conditions
  • Penetrate and hold good no predrilling needed
