Thomas Betts A-100-1/2 Regular Spring Nut 1/2 Inch Bolt

Product Description

The THOMAS BETTS A-100-1/2 is a regular spring nut designed for use with strut channel systems in commercial and industrial electrical installations. Manufactured from steel with an electro galvanized finish, this spring nut accepts a 1/2 inch bolt with a 1/2-13 thread size, providing a secure mechanical connection within the channel assembly. It seats and locks into strut channel without requiring access from the back of the channel, making it a standard hardware component for panel support, cable tray, conduit runs, and equipment mounting. Licensed electricians and electrical contractors install this hardware as part of larger strut-based support structures governed by NEC guidelines.

This spring nut is compatible exclusively with Thomas Betts Channel Type A strut profile. It is used in residential, commercial, and light industrial applications wherever strut channel support systems require field-adjustable bolt connections. Typical installations include electrical panel bracing, conduit support racks, mechanical equipment mounts, and suspended ceiling grid support. The electro galvanized finish provides basic corrosion resistance suitable for interior dry or semi-protected environments. Cross-reference part numbers for this item include Unistrut P101 and B-Line BLN225.

Installation Notes

Installation is typically performed by licensed electricians or electrical contractors following applicable NEC requirements for equipment support and grounding. De-energize any nearby electrical systems before working within an energized panel or raceway support structure. Insert the spring nut into the channel slot and rotate to lock before threading the bolt; do not overtighten by impact tools without verifying thread engagement. Verify the channel profile is Thomas Betts Type A before installing, as spring nut geometry is channel-specific.
