发明名称 PRESS-SET THREADED SCREWS AND 2 STROKE AIR TOOL FOR INSTALLATION
摘要 A press-set threaded screw assembly includes a first member having an aperture. A second member abutting the first member includes a threaded bore co-axially aligned with the aperture. A screw body includes a body flange, a neck portion, and a threaded member. The threaded member in a non-installed condition has first and second displacement portions separated by a tapered slot, each having a main thread portion. A pin is frictionally received in a bore created through the body flange and neck portion in a screw non-installed condition. The threaded member is inserted through the aperture and received in the threaded bore in an initial installation condition. The pin is axially aligned to slide into the tapered slot, whereby the pin oppositely displaces the first and second displacement portions away from each other to contact a plurality of female threads of the threaded bore, defining an installed condition.
