Application No. 09/105,150
a screw having a shank with opposite first and second ends and with an
external thread, and having a head on said first end of said shank, said second
end of said shank being circular and substantially planar; and
a deformation in a portion of said external thread adjacent said second
end of said shank, said deformation being a stake formed in said second end of
said shank and extending along a chord of said second end transverse to the
longitudinal axis of the shank;
whereby said deformation limits removal of said screw from said bore.
11. A terminal assembly, comprising:
a terminal having a base plate including a bore with an internal thread of a
first axial length;
a screw having a shank with opposite first and second ends and with an
external thread of a second axial length threadedly mating with said internal
thread, and having a head on said first end of said shank, said second end of
said shank being planar and circular, said second axial length being substantially
greater than said first axial length; and
a stake formed in and extending along a chord of said second end
transverse to the longitudinal axis of said shank, said stake creating a deformed
portion of said external thread having a reduced width between adjacent crests
thereof relative to other portions of said external thread, said deformed portion of
said external thread forming a stop which does not threadedly mate with said
internal thread.
16. A method of forming a terminal assembly, comprising the steps of
threading an external thread of a shank of a screw into a bore in a
terminal with an internal thread, the shank having opposite first and second ends
with a head at said first end; and
deforming a portion of the external thread adjacent the second end of the
shank to limit the amount the screw can be backed out of the bore by staking
said second end along a line extending across the second end and offset from
and perpendicular to a longitudinal axis of the shank.
