Description
When you’re fabricating custom brackets, extending threaded rods, or repairing equipment where the threads are damaged right at the connection point, you need a reliable way to join two pieces together. This zinc-plated threaded coupler does exactly that—it screws onto both ends of 5/16″-18 threaded rod and gives you a solid, permanent connection that won’t back out under vibration or load.
What You’re Getting
- 5/16″-18 internal threads on both ends for clean, secure connections
- 7/8″ length provides enough thread engagement for full strength
- Zinc plating resists rust and corrosion in outdoor conditions
- Hex-shaped body lets you tighten with standard wrenches
Perfect for Shop and Field Work
This coupler handles all sorts of repair and fabrication jobs around the farm. Whether you’re building custom implement brackets, extending tie rods on older equipment, joining threaded rod for adjustable stabilizers, or fixing damaged threads on loader arms, this little part solves connection problems that would otherwise require welding or complete replacement.
Made to Last
Farm hardware takes abuse from weather, chemicals, and constant vibration. The zinc plating on this coupler provides excellent corrosion resistance, while the quality steel construction handles the loads you’ll put on it. It’s the same type of connector used in commercial applications where reliability matters.
Installation Notes
Thread both rods in equally so the coupler stays centered on the joint. A drop of thread locker helps prevent loosening if the connection will see vibration. If you’re working with rusty or damaged threads, run a 5/16″-18 die over them first for smooth assembly.
