Channel Nut

Channel Nut
Not sure what nut you have?
Two ways to identify it - whichever is easier with what is in front of you.
1If you have the nut

Find the spanner that fits it snugly, then measure the hole. Our nut identification chart lists every metric and imperial nut we stock side by side, sorted by spanner size.

2If you have its bolt

The fastest check is the male thread: the right nut spins onto its bolt by hand with no force. Identify the bolt size and pitch first with our bolt and screw guide, and the nut follows.

Spring channel (strut) nuts are rectangular nuts with a captive spring that locks the nut into a slotted channel or strut profile (Unistrut, Powerstrut and similar). The spring holds the nut at any point along the channel until tightened — used widely in cable tray, pipe support and HVAC. We stock 36+ variants across the channel nut range.
