Simple question: how are people fastening the top extrusions in the Eustathios- the screw

Simple question: how are people fastening the top extrusions in the Eustathios- the screw head is too large to fit into the groove of the extrusion. Do we need to drill the hole wider, grind the screw head smaller, or just use long screws and tighten them on the outside of the extrusion?

Slide the screw heads in from the ends of the extrusion. Use the holes to access the screw heads in order to tighten them.

doh! damn, that’s ingenius. ok

thanks
