Drake Two-Piece Lock Nuts

Drake Two-Piece Lock Nuts, or Two-Piece Lock Nuts, are free-spinning two-piece lock nuts that can be positioned anywhere along the length of the thread. The two pieces give the nut double-locking action where the bottom nut's flexible slotted crown digs into a male thread as the second nut is fastened on top. This action locks the nut, providing superior holding power compared to prevailing torque style lock nuts in high-vibration applications.
