How a Spring Nut Works

A spring nut is a rectangular nut with grooves on top and a spring underneath. You push it into a strut channel and give it a quarter turn: the grooves lock onto the channel lips, and the spring holds the nut in position while you fit the bolt.

Applications

  • Cable tray and conduit supports
  • Pipe, duct and HVAC supports
  • Solar panel mounting structures
  • Electrical and MEP installations

Spring Nut FAQs

Which channel size does a spring nut fit?

Spring nuts are made to suit the channel width, most commonly 41 mm strut channel. Tell us the channel size and the bolt size in your enquiry.

Which bolt goes with a spring nut?

A hex bolt of the same thread and material, with a washer under the head. Choose a bolt length that passes fully through the spring nut but does not touch the bottom of the channel.

Which spring nut finish suits outdoor and solar structures?

Hot dip galvanized spring nuts suit galvanized channels outdoors, while zinc plated spring nuts suit indoor and mild conditions. Use SS 304 or SS 316 spring nuts with stainless steel channels, and do not mix stainless steel and galvanized parts outdoors.
