3.5x16 Optimaxx Premium Woodscrew 200pc Box

WHAT MAKES OPTIMAXX UNIQUE?

The consistent slash at the end of the screw is exclusive to Optimaxx and is designed to pull you in smoothly and quickly and to pull out the material from the hole. Above this self-drill point is a sharp serrated saw-tooth formation that cuts out of the bottom threads and bites into the timber to reduce torque and resistance. This enables fast penetration without a pilot hole, even when working close to the edge.
An exclusive feature you won’t find with no other brand on the market other than Optimaxx is the double reinforced collar which strengthens the underside of the head.
Finally, no other brand can outdo Optimaxx on their 500-hour spray test. With most competitors failing to meet the basic 400-hour salt spray test, this makes Optimaxx the strongest and most reliable woodscrew on the market.”
