Abb B9125/16 Spring Nut 5/16 Inch Strut Fitting

Product Description

The ABB B9125/16 is a 5/16-inch spring nut designed for use with channel strut framing systems. It provides a secure, tool-assisted threaded connection point within standard strut channel, allowing threaded rods, bolts, and fittings to be anchored without welding or drilling additional holes. The spring mechanism holds the nut in position inside the channel during installation, which simplifies alignment and speeds up assembly. Electricians, pipefitters, and mechanical contractors use spring nuts like the B9125/16 when building pipe hangers, cable tray supports, equipment mounts, and conduit runs supported by strut systems.

This spring nut is suited for both residential and commercial applications wherever channel strut framing is used as a structural support system. Common installation scenarios include mechanical room pipe supports, electrical conduit hangers, HVAC duct support frames, and general-purpose unistrut assemblies. The 5/16-inch thread size makes it compatible with standard 5/16-inch hardware used throughout strut-based support systems.

Key Features

• Spring-loaded design holds nut in place inside strut channel during installation
• 5/16-inch thread size fits standard strut hardware and threaded rod
• No welding or additional drilling required for installation
• Compact form factor suited for tight strut channel clearances
• Fits standard strut channel framing used in electrical, plumbing, and mechanical applications

Compatibility

Designed as an OEM-style replacement and standard-fit spring nut for use with conventional channel strut framing systems accepting 5/16-inch threaded fasteners.

Installation Notes

Installation is performed by electricians, pipefitters, and mechanical contractors working with strut channel support systems. Insert the spring nut into the open channel slot, rotate 90 degrees to engage the channel lips, and thread the fastener in place. De-energize any electrical circuits in the work area before installing conduit or cable tray hardware nearby. Follow applicable NEC and local mechanical code requirements for support spacing and load ratings.
