Jam Nut 3/8-24 Steel RH

The Jam Nut 3/8-24 Steel RH from FK ROD ENDS is a precision fastening component designed for marine propulsion systems, steering linkages, and rod end assemblies where secure, vibration-resistant connections are critical. Anglers and boaters operating in saltwater or freshwater environments rely on jam nuts to lock rod end bearings in place, preventing unwanted loosening caused by engine vibration, prop torque, and repeated mechanical stress. This right-hand threaded steel fastener is engineered to complement rod end ball joints commonly found in throttle cables, trim-and-tilt mechanisms, and custom steering fabrication.

Manufactured in steel with zinc oxide coating, this jam nut resists corrosion in the harsh marine environment while maintaining strong holding torque against the mating rod end bearing. The 3/8-24 thread pitch is a standard specification in marine rigging, offering fine-thread engagement that locks tighter than coarser alternatives and reduces the likelihood of self-loosening under continuous vibration. Right-hand threading ensures compatibility with conventionally wound rod ends and steering components used across most recreational and commercial vessel platforms. The compact 1.3-inch length and 0.5-inch diameter make it suitable for confined spaces typical of engine bays and transom-mounted hardware.

Boaters performing routine maintenance, engine rebuilds, or aftermarket steering upgrades will find this jam nut essential for reassembly of factory and custom rod end configurations. Install by threading onto the mating rod end stud, tightening snugly to lock the bearing without over-torquing, which could strip the fine threads. Sold individually, allowing you to replace worn or corroded units or maintain spares for remote fishing trips and extended cruising. Verify your rod end's thread size and hand orientation before ordering to ensure proper fitment and safe operation on the water.
