Spring Nuts

Channel nuts, also known as spring nuts, are a type of nut that is designed to be used with slotted metal channels like Unistrut or Superstrut. They have a closed shape on one side and a flat side with a threaded hole on the other side. The closed side has indentions or teeth that grip the edges of the channel when the nut is inserted.
