Top Gadget of 2006 — The HurriQuake Nail
eldavojohn writes "Popular Science is naming its Best of What's New of 2006 and the one at the top doesn't have much to do with circuitry or computers. Instead, it's a nail. Not your average nail though, the HurriQuake nail [flash] spent six years in development." From the article: "As the Bostitch team tweaked the head-to-shank ratio, Sutt and metallurgist Tom Stall worked on optimizing high-carbon alloys, trying to find the highest-strength trade-off between stiffness and pliability — the key to preventing snapped nails. 'Meanwhile,' Sutt says, 'we were focusing on how to keep the nail from pulling out.' The team machined a series of barbed rings that extend up the nail's shaft from its point, experimenting with the size and placement of the barbs. 'You want the rings to have maximum holding power,' he says, 'but if they go up too high, it creates a more brittle shank that shears more easily.'"
Haven't spent much time in construction, have we? Through college, I spent a couple summers framing houses. The days were long, and you'd come home exhausted, but you had to absolutely work your butt off if you wanted to come in on budget and actually make a buck after paying labor. Of course, I was one of the labor, but it was a small, family company I was working for, so I got an idea of how the business side actually worked. Screws are *slow* to install, compared with a guy and a nail gun. When every extra minute is eating into the bottom line, the extra time it would have taken to use screws would have "screwed" us.
Non-removable nails don't sound that bad to me - once you knew what the hell you were doing, you didn't screw up much, particularly with a nail gun that drove nails in so deep you couldn't easily get them out anyway. If you missed by a small amount, you generally just threw in another nail and left the first one (bent over, of course, if it was sticking out). If they hold better and fit in the ol' nail gun, bring them on!
