Services and Applications

We can build to meet customer specifications.
Slip-ON 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.

The Slip-ON 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.


The Slip-ON 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.
