A sharp saw-tooth formation cut out of the bottom threads bite into the timber reducing torque and resistance, enabling fast penetration without a pilot hole.
24 unique grooves self countersink into all materials without the need to counter bore.
A sharp, wide, deep thread formation coated with a unique lubricant facilitates fast continuous insertion.
Double reinforced collar strengthens underside of the head.
Wide, deep Pozi recess dramatically reduces cam-out.
Salt spray tested to 500 hours.
