T-Slotted Framing Structural Brackets
Connect T-slotted rails and reinforce joints for structural stability. Fasteners are included.
For technical drawings and 3-D models, click on a part number.
Concealed brackets mount internally and stay out of sight once installed.
Tee concealed brackets thread directly into a T-slot and use the included fastener to secure.
T-Slotted Framing Fasteners
Screw and nut sets or nuts secure brackets and other accessories to rails.
For technical drawings and 3-D models, click on a part number.
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.
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. Partially threaded nuts keep studs from traveling past the bottom of the nut and damaging your table.
Stainless steel nuts have excellent corrosion resistance. They are a good choice for use with stainless steel parts or in EDM applications.
