Coupling Nut for Threaded Rods

This MIDWEST FASTENER coupling nut connects two threaded rods end to end. It features 3/8"-24 threads and a Grade 2 steel construction with zinc plating. The design taps threads from each side to meet in the middle for a secure joint. It serves as a straight-forward hardware solution for extending rod length.

Suited for Light-Duty Rod Joining

Builders joining two 3/8"-24 threaded rods in low-stress applications will find this nut appropriate. The Grade 2 rating limits its use to non-critical structural connections. Buyers who need higher tensile strength or corrosion resistance beyond zinc plating should look at something else. It is not intended for high-vibration or heavy-load environments.

Fits Standard 3/8"-24 Rod Assemblies

The nut threads directly onto any compatible 3/8"-24 rod without special tools. Its zinc finish provides basic protection against rust in dry conditions. Using this coupler frees up the need for a single continuous rod of extended length. Ensure both rods have matching thread pitch for proper engagement.

Questions about this item

What thread size must the two rods have to work with the 3/8"-24 coupling nut?

Both rods need 3/8"-24 threads so they can screw into each end and meet in the middle of the nut.

Will a Grade 5 or Grade 8 threaded rod work safely with this Grade 2 coupling nut?

The nut is Grade 2 steel, so it will be the weaker link; the assembly strength is limited to Grade 2 capacity.

How can I confirm the zinc-plated coupling nut is properly installed after threading both rods in?

Check that both rods are visible in the centre meeting point and that the joint holds firm under load.
