Strut Channel Nuts with Springs
A spring plus serrated grooves that grip the lip of the channel provide a more secure hold than standard strut channel nuts.
Zinc-plated steel nuts are corrosion resistant in wet environments.
Galvanized steel nuts resist corrosion in wet environments better than zinc-plated steel nuts. They can also be used outdoors.
304 stainless steel nuts resist corrosion better than zinc-plated and galvanized steel nuts. They also have good chemical resistance.
316 stainless steel nuts have excellent resistance to chemicals and salt water.
Aluminum nuts are about half the weight of steel and resist corrosion in wet environments.

Strut Channel Nuts with Studs
There's no need for additional fasteners with these nuts—they combine a strut channel nut with a spring and a threaded stud. The spring plus serrated grooves that grip the lip of the channel provide a more secure hold than standard strut channel nuts.
Zinc-plated steel nuts are corrosion resistant in wet environments. 304 stainless steel nuts are more corrosion resistant than zinc-plated steel nuts. They also have good chemical resistance.

T-Slotted Framing Fasteners
Screw and nut sets or nuts secure brackets and other accessories to rails.
End-feed fasteners slide into the end of the rail to attach components. They form stronger connections than drop-in fasteners because more surface area touches the rail.
Drop-in fasteners fit directly into the T-slot to attach components—no need to disassemble your existing structure. However, they form less secure connections than end-feed fasteners because less surface area touches the rail.
Flanged button head screws have a wider head than standard button head fasteners, so you don’t need a washer for wide mounting holes.
Spring nuts hold themselves in place, so they won't slide down vertical rails.
Offset nuts have a mounting hole close to one end, so you can install them next to corners and rail ends.

Spring-tab nuts have a flexible tab on the side that holds them in place on vertical rails. It also compensates for different slot depths.
Spring-loaded ball nuts hold themselves in place, so they won’t slide down vertical rails. The ball glides over holes, so they’re easy to reposition.
