Thomas Betts A-100-3/8 Regular Spring Nut 3/8 Inch

Product Description

The THOMAS BETTS A-100-3/8 is a regular spring nut designed for use with strut channel systems in electrical and mechanical installations. Manufactured from steel with an electro galvanized finish, this spring nut accepts a 3/8 inch bolt with a 3/8-16 inch thread size. It seats securely inside Type A channel and provides a fast, tool-free positioning method before bolt tightening. Electricians and mechanical contractors use spring nuts when building pipe supports, cable tray hangers, equipment mounting rails, and similar strut-based assemblies. The electro galvanized coating provides corrosion resistance suitable for indoor and protected outdoor environments.

This spring nut is intended for use with Thomas Betts Channel Type A only. It is a standard component in commercial and light industrial electrical installations where strut channel systems are used to support conduit, cable trays, and mechanical equipment. The 3/8-16 thread size makes it compatible with standard 3/8 inch hardware commonly used in these assemblies. It is sold individually and is well suited for repair, retrofit, or new construction work requiring single-unit replacement or low-quantity installation.

Compatibility

Designed for use with Thomas Betts Channel Type A only. Cross-references with Unistrut Part Number P1008 and B-Line Part Number BLN228. Not intended for use with other channel types or profiles.

Installation Notes

Installation is typically performed by licensed electricians or mechanical contractors following NEC guidelines for equipment support and grounding continuity. Before servicing an existing strut assembly, de-energize all conductors and equipment supported by the channel. Insert the spring nut into the channel slot, position it under the desired bolt hole location, then thread and tighten the 3/8 inch bolt to secure the fitting. Do not over-torque, as this can deform the spring clip and compromise holding force.
