End-feed fasteners slide into the end of the rail to attach components.
Use double and triple fasteners to install brackets with multiple holes. They eliminate the need for a single nut and screw for each hole.
Self-aligning fasteners have a ridge that keeps them centered in the T-slot.

Drop-in fasteners can be placed directly into the T-slot to attach components—no need to disassemble your existing structure. They consist of a screw and nut.
Spring and spring-tab fasteners hold the nut in place so it won't slide down vertical rails.
Hammer fasteners drop in to the slot and turn into place when the screw is tightened. They're serrated to break the anodized coating on the rail, allowing static to dissipate.

T-Slot Nuts

Designed to slide into T-slot tracks on machine tool tables, use these nuts to secure clamps and workpieces.
Fully threaded nuts allow a stud to extend beyond the bottom of the nut.
