8040 4040 Aluminium Extrusion Tee Nut

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4653064.

A simple tee nut for 4040 8040 etc aluminium extrusion with an M5 suitable hole.

An M5 screw self-threads easily into the 5mm hole.

Can be inserted and extracted directly, no need to slide in from the ends.

I used it to hang a mains extension lead. Probably not recommended for anything structural!
