Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

4130 alloy steel has a low carbon content that provides good weldability. It's often used for gears, fasteners, and structural applications.

Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, rollers, and bushings.

Push these brackets into strut channel and tighten the included cam screws for a partially concealed connection.

This welded, one-piece strut channel combines two strut channels side-to-side.

Up to two times the height of regular strut channel, this high-profile channel is stronger than regular strut channel.

Half the height and the same width as regular strut channel, this low-profile strut channel fits into tight spots and is compatible with many of the same brackets.

This welded, one-piece strut channel combines two strut channels back-to-back.

Position two strut channels at a 30° to 60° angle, then tighten the bolt to secure.

A tab on the end of these shelf brackets fits inside the strut channel for extra stability.

Slip these hangers onto the lip of top-opening strut channel to attach chain, wire rope, pipe, and threaded rod.

Brackets mount on the outside of strut channel to allow trolley movement.

Create a four-sided raceway for cable, or give a more finished look to strut channel structures.

There's no need for additional fasteners with these nuts—they combine a strut channel nut with a spring and a threaded stud.

Cover rough ends of strut channel.

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

Quickly attach these nuts by twisting them closed at any point along a threaded rod.

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.

Add hardware to strut channel without having to hold the washer in place or reach inside the channel.

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

Provide a stable, nonmarring base for strut channel legs.

Create posts of varying lengths.
