▲Slide the Pre-drilled threaded fastener through the installation material
▲Rotate the nut onto the fastener(slotted portion away from the installation material)
▲Apply the appropriate torque to the nut
▲If the bolt has no hole, once it is torqued properly drill a hole between two of the slots
▲Rotate the nut +/- 30% to align the hole with the slots in the nut
▲Slide the cotter pin through the slots, into the hole and out the other side
▲Using pliers, bend the cotter pin so that it cannot freely come out of the hole
