Spring Nut, 1/2"-13 Thread, 1/2" Thickness, Steel With Zinc Finish

B-Line spring nuts make strut connections fast, secure, and adjustable—ideal for trapeze hangers, brackets, clamps, and support frames. The spring holds the nut in place for easier one-person installs, while the “twist-and-lock” design lets you position hardware anywhere along the channel and fine-tune alignment without drilling. Built for dependable grip and long-term performance, B-Line spring nuts help reduce labor time and deliver clean, professional strut assemblies.
