I would like to put some threaded inserts into my finished carbon fibre piece, bonded like you guys did with the fittings on the car bonnet instructional video project. I have see Warren mention 'off the shelf' inserts that have the perforated or scored load plate on them for better bonding but can't find a source of these off the shelf inserts. 

I have used what is called T nuts. These are usually meant for timber furniture and you can see they have these 4 spikes sticking up which would normally key into the wood.
