Flex Type Lock Nuts is an all-metal, one-piece, hex-shaped lock nut with a round collar at its back end. The collar is segmented with opposed slots cut into it above each corner of the nut. When the screw or bolt reaches the collar, the slotted portion expands which creates the prevailing torque locking action.
The real secret of the FLEXLOC® design, however, is the slotted locking feature. As the bolt engages the locking feature, the slotted section expands, initiating the locking action. This expansion lifts the nut upward, causing the threads to bear against the lower surface of the bolt threads.
Flexloc nuts are reusable for a limited number of times except unplated stainless steel nuts, which are not recommended for reuse. Always follow the manufacturer's recommendations regarding nut reuse, thread lubricants and torque values.
