The ABB A1005/8 is a spring nut designed for use with S-Strut framing channel systems. Spring nuts insert into the open slot of strut channel and lock in place under tension, providing a secure threaded attachment point for hanger rods, pipe clamps, equipment supports, and other hardware. This hardware is sold in a 100-unit pack and is a standard fastener component used by electricians, plumbers, pipefitters, and mechanical contractors in both new construction and retrofit applications. The pack ships in a box measuring 8 inches long by 21.5 inches wide by 6 inches high and weighs 14 pounds per 100-unit pack.
Spring nuts are used wherever strut channel serves as the primary support structure — suspended ceiling grids, pipe and conduit runs, cable tray supports, and mechanical equipment mounting. They are a routine consumable on commercial and industrial job sites and are compatible with standard S-Strut channel profiles. Installations follow typical mechanical support requirements under applicable building and electrical codes.
Designed for use with S-Strut framing channel systems as a standard spring nut replacement or supply component for strut-based support structures.
Spring nuts are installed by electricians, pipefitters, plumbers, and mechanical contractors working with strut channel support systems. To install, tilt the nut diagonally to insert it into the channel slot, then rotate it flat so the spring seats against the channel rails. Ensure the channel run is adequately secured before loading the spring nuts with hardware. Follow applicable NEC, IPC, or IFGC support-spacing requirements for the system being hung.
