DOTTIE RC5 coupling nut 5/8-11

The DOTTIE RC5 coupling nut is a steel fastener with 5/8-11 threads and a zinc-plated finish. It comes in a pack of 25 pieces for bulk use. This hardware suits maintenance crews and assembly lines that need a reliable supply of coupling nuts.

5/8-11 thread specification

The single specification that decides fit is the 5/8-11 thread size. Only rods or studs cut to that exact pitch will engage correctly. Builders using any other thread diameter or pitch cannot use these nuts.

Integrates with threaded rod assemblies

Each nut measures 2-1/8 inches long and joins two threaded rods or extends a single rod. The zinc plating resists corrosion in damp environments. Buyers who need a different thread size or a smaller quantity should look elsewhere.

Questions about this item

What does the 5/8''-11 thread size mean when I use these coupling nuts on a job?

The 5/8''-11 thread matches rods or bolts with that diameter and 11 threads per inch, letting you join two threaded lengths end-to-end.

How does the zinc plating hold up in practice?

Zinc plating gives a sacrificial layer that resists corrosion on steel, suitable for indoor and general outdoor use.

What length of threaded rod do I need to engage the full 2-1/8 inch body?

Each nut is 2-1/8 inches long, so both rods must thread in far enough to meet near the centre for full strength.
