Interest spikes in
revolutionary nailClemson grad’s
invention, designed to resist hurricanes, honored by Popular

Clemson engineering alumnus Ed Sutt might just have nailed his
spot in history.
Sutt has invented a better nail, a staple of construction that
has changed little since the Roman Empire — one that could be a boon
to contractors working in hurricane and earthquake country.
The new and improved sheathing nail developed by the 38-year-old
former home builder has been recognized by Popular Science as the
magazine’s 2006 Innovation of the Year.
“I have difficulty grasping how big this has become,” Sutt said
from his fastener lab in Rhode Island. “You get so involved in a
project, you get sort of numb to the revolutionary nature of it.
“I’m still asking whether this is just an evolutionary step
toward to the ultimate nail.”
The HurriQuake nail, developed by Sutt in his work as a fastener
engineer at Bostitch, could dramatically reduce hurricane and
earthquake damage to homes and other structures.
Clemson estimated the carbon-steel alloy nail would raise the
price of a new home about $15.
The HurriQuake features angled barbs to resist pulling out in
wind gusts of up to 170 mph. The top of the nail shank is twisted to
reduce wobbling by boards, and the nail head is about 25 percent
larger than the average sheathing nail. Sheathing nails are designed
specifically to apply plywood sheathing to floors, side walls and
roofing of buildings.
Scott Schiff, a civil engineering professor who taught Sutt and
works in the Clemson Wind Load Test Facility, said the company’s
challenge will be winning over builders. In addition to the modest
increase in cost, the nail will be substantially more difficult to
remove, he said.
Schiff said he hopes builders and regulators will recognize the
dramatic increase in the strength of structures built with Sutt’s
nail.
“This potentially could make a huge difference on insurance
premiums and housing codes,” he said.
The HurriQuake nail has as much as twice the resistance to being
pulled out of framing or having its head pull through the sheathing
on a house, independent testing has shown.
Currently, the nail only is available in hurricane-prone coastal
areas from North Carolina to Texas, but Bostitch is adding new
production lines to meet increased demand, Clemson said.
Nails came into widespread use to replace wooden pegs during the
Roman Empire period 2,000 years ago. For centuries, nails were made
one at a time by blacksmiths. Schiff said it is obvious nails were
scarce and expensive when Charleston’s Colonial-era houses were
built, because many wooden pegs were used to hold the homes
together.
In 1795, Jacob Perkins received a patent for a process to
mechanically cut and put heads on nails.
And then came Sutt. He understands his nail could substantially
improve the survivability of houses in hurricane zones.
“The invention of the nail allowed the Romans to put things
together quickly,” Sutt said. “This just allows us to do it
better.”
