Spring washer are mainly punched out from iron plates. Spring
washer: after lock, use elastic pad have the effect of locking, and
of course to a double nut effect is poor.
Single nut + flat mat, play mat: rely on the nut itself locking
force and elastic cushion locking performance, a double nut.
Flat washer: only increase the surface area Prevent the soft
substrate was installed a damaged, or is blocking hole.
Locking method still has a lot of, this is just a very old some
basic locking method, but also very practical.
Trampoline's role is to prevent the screw loose caused by the
vibration of the machine or heat bilges cold shrink.Role is flat
mat, increase the contact area of the screw and machine 1, 2,
eliminate the trampoline at the time of discharge screw damage on
the surface of the machine must be a spring when using a flat mat,
flat pad close to the surface of the machine, spring cushion
between the plain washers and nuts.
Flat mat role is long screw is screw is half buckles added flat
washer cap can take full 2 is the place on the screw hole is too
large added a flat washer not leak down
Trampoline is mainly used for locking, used in vibration is not
big, if the vibration is big, generally want to use the double nut
locking or other locking method, flat washer is mainly used to
increase the contact area, like on the bearing seat because the
drive is long and narrow hole, must be the home of the flat washer.

the head of bolts and nuts. The toothed elastic washer is smaller
