Also known as insert nuts, these convert slotted holes to threaded round holes and keep them centered in the channel.

In addition to serrated grooves for gripping the lip of the channel, these nuts have wings for easy positioning.

A spring plus serrated grooves that grip the lip of the channel provide a more secure hold than standard strut channel nuts.

Insert these nuts into the long open side of strut channel and twist to secure. A built-in washer enables one-handed installation.

A tab fits tightly against the lip of the channel to keep these nuts from slipping.
