Serrated grooves grip the lip of the channel.

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.

Push these nuts into place rather than threading them onto a fastener.

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