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.
Center Hole and
Flanged Button Head
Offset Hole and
Flanged Button Head
Flanged button head screws have a wider head than standard button head fasteners, so you don’t need a washer for wide mounting holes.
Nuts with threadlocker have an adhesive on the threads that prevents loosening due to vibration.
Use double and triple nuts to install brackets with multiple holes. They eliminate the need for a single nut and screw for each hole.
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-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.
Flanged button head screws have a wider head than standard button head fasteners, so you don’t need a washer for wide mounting holes.
Nuts with a handle are easy to grip and drop in place. The flexible rubber handle bends to fit underneath objects mounted to the rail.
Hammer nuts drop in to the slot and turn into place when the screw is tightened.
Offset nuts have a mounting hole close to one end, so you can install them next to corners and rail ends.
