Self-Retained Nut Resistance Weld

       A nut is projection welded onto a clip which permits a
quick assembly of a nut with a knurl, a mounting flange, a cover, and
a bolt to fasten these components.

      Fig. 1 illustrates a clip 6 used to hold the assembly in place
prior to bolting the assembly together.  In Fig. 2, a nut 2 with a
knurl 4 is projection ring welded onto clip 6 at points 12.  This nut
and clip assembly is slipped onto a mounting flange 8, where knurl 4
is interference fitted into a hole 14.  A cover 10 is placed over the
assembly.  A bolt 16 is inserted through cover 10, clip 6, mounting
flange 8, and screwed in the threading in nut 2 to fasten the
assembly together.

      Fig. 3 illustrates a different shaped clip 20 used to hold the
assembly together.  In Fig. 4, nut 2 with knurl 4 is projection ring
welded onto clip 20 at points 22.  This nut and clip assembly is
slipped onto mounting flange 8, where knurl 4 is interference fitted
into hole 14.  Cover 10 is placed over the assembly.  Bolt 16 is
inserted through cover 10, clip 20, mounting flange 8, clip 20 again,
and then screwed in the threading in nut 2 to fasten the assembly
together.
