The Story of the
Drywall Screw
The history of the drywall screw includes many
products and patents-and at least one inventor
who started his business in his garage .
Charles D . Cannon of Cleveland invented
"sheet-metal fastening" in 1930-U .S . Patent
1,749,903 . The screw could fasten metal together without using nuts and bolts .
In the 1950s, Paul S . Quigg of Barrington,
Ill ., studied fire protection and screws . The
screws Quigg developed fastened drywall to
vertical steel studs . "These were to the building
industry what transistors and chips were to the
computer," says the Chicago Tribune .
As a carpenter, Bob Weber of Island Acoustics
in Bohemia, N .Y ., remembers drilling holes and
using No . 8 nuts, bolts and washers to fasten
walls together . He says Parker-Kalon introduced
self-tapping screws in the late 1950s-"we called
them 'P-K screws .'"
In 1965, Simon S . Kahn of Glen Ridge, N .J .,
invented "wallboard screws"-U .S . Patent
3,177,755 . Kahn's screws were "adapted to fasten a wallboard upon an underlying support ."
Next came Robert H . Dylson's 1967 "drill
screw ." Dylson of Morton Grove, Ill ., and assignee Illinois Tool Works, invented "drilling and
fastening a first work member to a harder
second work member," states U .S . Patent
3,358,548 . The drill screw had "a pair of frangible
wing-like elements on the shank ... capable of
boring a hole ."
In 1969, Ned Joseph Gruca of Elgin, Ill ., patented the "screw type fastener"-U .S . Patent
3,478,639 . Assigned to Illinois Tool Works,
the screw could fasten metal, sheathing and
foam insulation material . It had two thread
"convolutions"-one of high thread pitch, the
other of low thread pitch .
John "Brad" Wagner began selling screws
from his garage in Walnut Creek, Calif ., in
1967 . The engineer and graduate of Rensselaer
Polytechnic Institute sought ways to improve
screw designs . In 1970, Wagner introduced
the Grabber, a screw with coarse threads . In
1972, he invented the Grabber Streaker (shown
here) . The Streaker had twin lead threads and
a sharp 23-degree point . Wagner patented
the design in 1976 (U .S . Patent 3,942,405),
and Construction Dimensions dubbed it "the
accepted drywall screw ."
In 1998, Wagner received AWCI's President's
Award for his contributions to the industry .
His company also became an AWCI Lifetime
Member .
