Dexter Hex Lock Nut 7/16-20, Zinc Plated, 006-257-00

The Dexter 006-257-00 is a 7/16-20 hex lock nut with a zinc-plated finish, used as hardware for trailer brake actuators. The nut measures 0.25 inches thick and is designed to thread onto a 7/16-20 stud or bolt while resisting loosening from vibration, a common requirement on trailer running gear and brake components. The zinc plating provides a protective, corrosion-resistant surface suited to the exposed conditions trailer hardware typically sees.

This is a small, precise replacement fastener rather than a full kit, making it useful when a single nut is lost, damaged, or worn during trailer brake actuator service or maintenance. At just 0.01 pounds, it ships easily alongside other small hardware items.
