Choosing a coupling nut
Match the thread form and size to the rod or bolt you are joining, and choose the finish for the environment: zinc for dry indoor use, hot dip galvanised for outdoor use and 316 stainless steel for corrosive conditions. For lifting or structural joints do not rely on a standard coupling nut unless the manufacturer rates it for the load. Always check the data sheet for sizes, grade and load rating of the exact nut before you order.

Coupling Nut FAQs
What is a coupling nut used for?
A coupling nut is a long nut that joins two threaded rods or bolts end to end, or extends the length of a threaded rod.
Can I use a coupling nut for a lifting application?
Only if the manufacturer rates the nut for the load. A standard coupling nut is not a lifting component. Check the data sheet and, for lifting or structural joints, confirm with the engineer.
Do you stock coupling nuts in other threads?
Metric, UNC and BSW coupling and coupler nuts are listed, along with a Champion assortment kit. Call us if you need a thread that is not listed.
