There is only one Unistrut Metal Framing System. It incorporates the innovative product improvements that our research and development group has created to give you the most complete and flexible support system available. Backed by our worldwide network of engineering and distribution centers, Unistrut provides customers with total-resource capability.
We invented it. The one you know, the one you trust, the one you ask for by name… Unistrut, accept no substitute.
 Hex-head bolt threads easily into a spring nut, connecting fitting to channel in one quick one-hand operation.
 Chamfer in the nut eases starting of the bolt. Nut teeth create a strong, vise-like grip when tightened against the inturned channel edges.
 Channel edges and the nut's tapered grooves act as guides to provide fool-proof alignment of connection.
 Nut teeth create a vise-like grip, tying sides together in a strong “box” configuration, when the nut is tightened against the in-turned edges.
 Spring allows precision placement anywhere along channel length, then holds the nut in position while connection is completed.
