An essential for working with slotted aluminum 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.
