Dexter Hex Lock Nut, 1/2-20, Zinc Plated - Trailer Brake Actuator Hardware, Part 006-256-00

The Dexter 006-256-00 is a hex lock nut sized for 1/2-20 threaded studs and bolts, finished in zinc plating for corrosion resistance. It is used as trailer brake actuator hardware, securing components in the actuator assembly against loosening from vibration and repeated cycling during towing. The hex head allows the nut to be tightened and removed with a standard wrench or socket, and the lock feature is designed to hold torque over time rather than backing off under load. At 0.03 pounds, it is a small, lightweight fastener meant to be paired with the correct matching stud or bolt of the same 1/2-20 thread pitch. This is a genuine Dexter part, identified by part number 006-256-00, intended as a direct replacement when the original hex lock nut on a trailer brake actuator is worn, corroded, or missing.
