Unique Net-Coat plating withstands the elements and works to combat the effects of galvanic corrosion, providing 1000 hours+ protection.
CPT hardened to provide an ultra strong core strength, the screws should not snap and in most applications, there's no need to pilot.
A coarse, single thread clamps boards fast with a high pull-out retention whilst the partial thread prevents 'jacking' of the materials.
Patented Tri-Lock thread expands timbers for a fast drive with reduced torque, the timbers then contracts around the screw for a solid fix that will not work loose.
Double collar provides strength and allows for a deeper recess for a secure drive with reduced cam-out.
Ideal for use in decking, pressured treated timbers, fencing and outdoor structures.
