An essential for working with slotted Aluminium extrusion, these slim metal nuts slide into the ends of the extrusion. The oval shape means that as they screwed-into the nut jams against the slot. This is for our 20x20mm slotted extrusion, not "OpenBeam" 15x15mm
This product comes as a bag of 50 T-nuts, with M4 threads. If you want to be a little more lux, check out our "slim" T-nuts that be dropped into the slot from the side rather than from the end. Works with any of our M4 screws.
