Thomas Betts B911-1/4 Spring Strut Nut 1/4-20 100 Pack

Product Description

The THOMAS BETTS B911-1/4 is a spring strut nut designed for use with 1-1/2 inch deep strut channel systems. It features a 1/4-20 inch thread size and a Galv-Kron finish that provides corrosion resistance in exposed or damp installation environments. This hardware is used to secure threaded rod, bolts, and fittings to standard strut channel without welding or drilling additional holes. Electricians, mechanical contractors, and pipefitters install these nuts when building unistrut-style support systems for conduit, cable tray, HVAC equipment, and piping runs. Each package contains 100 nuts.

Spring strut nuts are a standard component in electrical and mechanical support assemblies across residential, commercial, and industrial applications. The spring-loaded design allows the nut to be inserted into the channel slot and rotated to lock in place, enabling fast positioning along the channel length before final torque is applied. These are commonly used in suspended ceiling grid support, equipment mounting, and seismic bracing installations where repeated adjustment is needed during rough-in.

Key Features

• Spring-loaded design locks into channel slot without tools for quick positioning
• Compatible with 1-1/2 inch deep strut channel
• 1/4-20 inch thread size accepts standard 1/4 inch bolts and threaded rod
• Galv-Kron finish provides corrosion resistance for damp or exposed locations
• Sold in a 100-count package for high-volume installation work

Compatibility

Designed for use with 1-1/2 inch deep strut channels and 1/4 inch bolts. Confirm channel depth and bolt diameter before installation.

Installation Notes

Installation is typically performed by licensed electricians or mechanical contractors following NEC and applicable local code requirements. De-energize any nearby electrical systems before working in the vicinity of live panels or conduit runs. Insert the nut into the channel slot at a 90-degree angle, then rotate to engage the spring clip before threading the bolt. Do not overtighten without verifying the channel manufacturer torque guidance.
