What is a channel spring nut you ask? It’s a channel nut, with a spring on one side, that slides inside of a piece of strut channel designed to decrease your installation time.
The spring takes up the extra space inside the channel, keeping the nut flush against the in-turned edges of the channel, so you don’t need an extra hand to hold it in place, while you’re busy trying to affix parts and tighten them down.
Channel nuts, including spring nuts, typically have a threaded hole in the middle which is used to attach fittings to the strut. Strut & Support Solutions nuts are available with a variety of hole sizes, to accept a range of hex head cap screw (hex bolt) sizes.
Channel Nuts and spring nuts also have serrated grooves on one side to help you correctly align them within the channel’s track, and hold them securely in place, during the tightening process and after being tightened.
