The present invention provides a non-threaded insert operable to transfer
or couple a mechanical load to a structure. This non-threaded insert
includes an upper insert having a noncircular cross section and a lower
insert. The coupled upper and lower insert are received within the
structure and are operable to receive a mechanical load which is then
distributed to the structure. The noncircular cross section of the upper
insert is received within a noncircular receptacle wherein rotation of
the upper insert within the receptacle is inhibited by mating the
noncircular cross section of the upper insert within the noncircular
receptacle. This allows mechanical loads to be distributed to be better
coupled to materials such as composite materials wherein traditional
thread fasteners would intensify mechanical stresses within the coupled
threads.
