The ABB B-914-5/8 is a channel square nut designed for use with strut channel framing systems. It features a 5/8-11 thread size and a body thickness of 3/8 inches. Constructed from steel, this nut is sized to drop into standard strut channel slots and torque down against the channel flanges, creating a secure attachment point for threaded rod, pipe hangers, equipment supports, and other hardware. Electricians, plumbers, and mechanical contractors rely on channel nuts like this one to build out support structures in commercial and residential installations.
This channel square nut is used wherever strut channel framing is installed as a support system. Common applications include pipe and conduit hangers, equipment mounting rails, cable tray supports, and unistrut-style framing assemblies in mechanical rooms, ceilings, and utility spaces. The 5/8-11 thread size suits heavier-duty fastening applications within standard strut channel track.
Designed as an OEM-style replacement and standard hardware fitting for use with standard strut channel framing systems in mechanical, electrical, and plumbing support applications.
Installation is typically performed by licensed electricians, plumbers, or mechanical contractors working under applicable NEC, IPC, or IFGC support and hanger requirements. Drop the nut into the strut channel slot at the desired position, then align and thread the fastener before tightening. Ensure the strut channel run is de-energized or isolated from active systems before working in energized panels or raceways. Do not overtighten beyond the fastener and channel manufacturer specifications.
