Dirt King Jam Nuts are low‑profile locking nuts designed to secure threaded rod ends and prevent unwanted rotation in suspension and steering assemblies. These jam nuts are zinc plated to resist corrosion and provide durable locking performance in high‑stress environments.

Sold individually, each jam nut offers a reliable locking solution for adjustable linkages, clevises, and other threaded components where secure positioning is critical. Their compact design allows them to be used in tight spaces while ensuring a firm lock on threaded connections.
