Lock Nut is a maintenance time saver with multiple applications
for electricians, mechanical contractors, plumbers, steamfitters,
general contractors, mining contractors, telecommunications industry
personnel, etc. These lock nuts can be used either as stops or quick-change
adjustments on molds, dies, fixtures, and jigs using bending machines,
lathes, extruders, industrial cutters, fabricating machinery in
general, plus a lengthy list of other applications.
The lock nut consists of an assembly of two permanently joined,
independently rotatable slotted nuts, designed for direct slip
on installation and compression-type locking action. The nuts are
six-sided with one of the sides removed to form the slot in each
of the nuts. The slotted nut looks similar to a horseshoe. Users
install the nut assembly by rotating both nuts to the nut assembly
by rotating both nuts to the open position. In the open position,
with the open slots of the two nuts aligned, users slip tech assembly
on or off a threaded rod or bolt therefore eliminating rundown.
On the closed position, with the slots of the nuts opposite each
other, users tighten the nuts with conventional wrenches. This arrangement
of nuts provides high clamp loads or torque specification comparable
to those obtained with standard nuts. The clamp load or torque specification
depends on the size of the nut. The Slip-ON Lock Nut also gives
a compression-loaded locking action which is extremely resistant
to the loosening effects of vibration because it uses two nuts stacked
end-to-end. Users remove them by loosening the nuts as units and
then aligning the slots or the two halves.
Lock Nut is patented in the U.S., Canada, Japan, and Europe. The
patent covers both physical apparatus as will as method of manufacturing.
It is available in zinc plated steel and stainless steel in metric,
UNC, and UNF.
Lock Nut eliminates the need to spin nuts to the desired location,
bypasses damaged threads on a threaded rod or bolt, and speeds up
project completion time. Another benefit is the nut's superior anti-vibratory
characteristics. The Detroit Testing Laboratory technicians conducted
a test to evaluate the vibration resistance of the Slip-ON Lock
Nut's locking action. The technicians torque the nuts to 50 foot-lbs.
And then subjected them to a three-hour test consisting of five-minute
periods of sinusoidal vibration at frequencies ranging from 5 to
2,000 Hz, double amplitudes as high as 0.4-inch displacement, and
generated shaking forces as high as 35 G's. The technicians concluded
that the nuts were not loosened.
