From Popular Science:
Hurricane winds rip apart nailed-together walls, and earthquakes shake houses so violently that a nailhead can pull straight through a piece of plywood. Since we can’t stop natural disasters, Bostitch engineer Ed Sutt has dedicated his career to designing a better nail. The result is the HurriQuake, and it has the perfect combination of features to withstand nature’s darker moods. The bottom section is circled with angled barbs that resist pulling out in wind gusts up to 170 mph. This “ring shank” stops halfway up to leave the middle of the nail, which endures the most punishment during an earthquake, at its maximum thickness and strength. The blade-like facets of the nail’s twisted top—the spiral shank—keep planks from wobbling, which weakens a joint. And the HurriQuake’s head is 25 percent larger than average to better resist counter-sinking and pulling through. The best part: It costs only about $15 more to build a house using HurriQuakes. $45 per 4,000.
