includes a longitudinally extending bore 17 and a counterbore
18 having a diameter somewhat greater than the diameter of the
bore 17. Horling teaches (column 2, lines 35-62) that the
insert 25 is disposed in counterbore 18 and is formed of a
material, such as compressed fiber, softer than the material
of the body 16. The insert 25 has a bore 26 disposed
coaxially of the bore 17. The bore 26 has a diameter somewhat
less than the diameter of the bore 17 and somewhat less than
the diameter of the screw threaded end 30 of a spoke 15 so
that the spoke can be self-threaded into the bore 26 of the
insert 25.
Sauer discloses a self-locking nut. As shown in the
figure, the self-locking nut includes a metal body 10 having a
threaded bore 12 and a locking collar 16 having a bore 18
disposed in a recess 14 formed in the body 10. Sauer teaches
(column 1, lines 20-27) that the bore 18 of collar 16 is
somewhat smaller than the diameter of the thread 12 so that
when the nut is screwed on a bolt, the bolt thread impresses a
thread in the collar 16. Sauer also teaches (column 2, lines
45-55) to make the locking collar from nylon for the following
