Stanley-Bostich’s Hurriquake nail incorporates features that enhance its ability to resist both the side-to-side shearing action of earthquakes and the uplift caused by high winds during hurricanes. But designing stronger nails is easy. Bostitch’s real engineering feat is designing stronger nails that still fit in any modern nail gun.
It’s a ring-shank nail, which helps to keep the nail and whatever it’s holding down from parting company. A wide screw-shank section under the head of the nail compensates for the wider hole made by the barbed ring and adds more holding power, while a larger nail head provides 25% more area to prevent pull-through. And a huge amount of metallurgy research went into making a carbon steel alloy with the proper stiffness while remaining pliable enough to prevent shear.
The bottom line: plywood sheathing attached with Hurriquakes has a much better chance of staying put in adverse conditions.
And while the Hurriquake does cost a little more than standard nails — they run $40 per 5,000 — that translates to something like $15 more per house. That’s a small price to pay for peace of mind.
Note: The Hurriquake was PopSci’s Best of What’s New grand award winner last year. Check out their video interviews with Ed Sutt, the Hurriquake’s inventor and Stanley-Bostitch’s “Dr. Nail.”
