gripping parts 25 are axially staggered or offset,
the part 25 at vthe lefthand side or" Fig. 1 being
in a plane slightly above the plane of the part

with the side l5, The base portions I2 and I5
are not directly connected or joined and are free
for relative movement. It is to be observed that
the body i5 just described is a simple, inexpensive
one-piece element.
It is a feature of the invention that the fastener Y
or nut may be provided with as many gripping
parts or lock parts as required. Thus the nut
may have two, three, four, iive or more locking
or gripping parts. The clamp, clip, nut or
fastener of the invention may be used on pins,

in addition to the base portions I2 and iii which Si)
also grip or lock with the thread T of the bolt i i.
Thetop Irl may be provided with a pair of
locking >or Vgripping parts I3. The‘top Iii has an
opening for receivingr the bolt I i and the gripping
parts is are arranged at opposite sides of the
opening to cooperate with the bolt. The parts
i8 may be formed by making two parallel cuts»
in the top Ill and bending 0r striking up the metal
between these cuts. The locking or gripping
parts `Iii may be straight or bowed, as preferred,
andthe inner or active edges I9 lof the parts iii
may be straight or curved. In the particular`
case illustrated the edges I9 are concave, it being
understood that they may be straight, convex, or
waved, as desired. The active edges I9 oi the
parts i8 are not directly opposite but are offset
axially of'thebolt, to have more effective binding
or gripping cooperation with the helical thread

of the portion I6 so that the walls of the opening
may bite 'into the thread T. The lock or grip
part 2l is formed by bending back the material
at the inner extremity of the base portion I5.
The part 2l is pitched upwardly and inwardly
to `,have its'edge cooperate with 4the bolt thread
T. Therpart 22 cooperates with the bolt II in a
plane below the plane occupied by the active
edge of the gripping part 2l to obtain a better
locking orgrippíng action. The active edges of
the gripping parts 2i and 22 maybe straight,
pitched or waved, as desired. From'an inspec
tion of Fig. 1 of the drawing it will be'seen -that
the gripping parts Iï8, 20 and 22 at one side of the
nut have their active edges below the active edges
of the complementary gripping parts at the other
side of the nut. This vaids in causing the nut to
lock or bind on the bolt.
In addition to the locking or gripping parts i8,
20, 2| and >22, one or more gripping parts may
befprovided on the base -portion I2. An opening
24 is provided in the base por-tion I2 to receive
the bolt II. In the construction illustrated a
