Thomas Betts B-100-1/2 Short Spring Nut Strut Channel

Product Description

The THOMAS BETTS B-100-1/2 is a short spring nut designed for use with strut channel systems in electrical, mechanical, and plumbing support applications. Manufactured from steel with an electro galvanized finish, this hardware component threads onto a 1/2-13 in bolt and seats securely inside the channel to allow quick, tool-free positioning before final torque. The spring action holds the nut in place along the channel track, speeding up layout and reducing dropped hardware during overhead or vertical installations. Electricians, mechanical contractors, and plumbers use this nut wherever strut channel is used to support conduit, pipe, ductwork, or equipment.

This short spring nut is rated for use with Thomas Betts Channel Type B strut channel only. It is a standard component in commercial and industrial construction, used in data centers, mechanical rooms, electrical rooms, and any installation requiring adjustable channel-mounted support hardware. The short profile suits applications where clearance inside the channel is limited or where a flush, low-profile seating is preferred over a standard-height nut.

Key Features

• Short spring nut profile for low-clearance channel installations
• Electro galvanized steel construction for corrosion resistance in typical indoor environments
• 1/2-13 in thread size accepts standard 1/2 inch hardware
• Spring-loaded design holds nut in position during layout before bolt tightening
• Compatible with Unistrut P4010 and B-Line N525 as cross-reference part numbers

Compatibility

Designed for use with Thomas Betts Channel Type B strut channel only. Cross-references to Unistrut part number P4010 and B-Line part number N525.

Installation Notes

Installation is typically performed by licensed electricians or mechanical contractors working with strut channel support systems. Insert the spring nut into the channel track, rotate to lock, and thread the bolt through the fitting before final tightening. Follow applicable NEC or IPC guidelines for support spacing and load ratings on the overall strut assembly. Do not use this nut with channel profiles other than Thomas Betts Channel Type B, as dimensional differences may prevent proper seating and secure engagement.
