Metric Coupling Nuts

Metric Coupling Nuts connect any two threaded items like two pieces of threaded rod. They have coarse right-hand machine screw threads at both ends. Length is dependent upon size, which is about 3 times the size of the nut. Choose from zinc plated steel and stainless steel. They are also known as Extension Nuts and Hex Spacers.
