Bi-Way Lock Nut
These nuts have a locking mechanism in the middle of the nut so they can be installed in either direction. It locks onto the mating part by slightly compressing the threads in the locking section of the nut. This permanently distorts the threads of the mating part.
Other Names: Two Way Lock Nut, Reversible Lock Nut, Centerlock Nut
