I think I'm better off just using an M5 and then putting some shrink wrap over the first 5mm of threads. I just got all excited about being able to have an M6 bolt to fill up the 6mm hole
Maybe sleeve a long M5 with 6mm x 5mm brass tube? Bond the sleeve in place with Araldite or Chemical Metal if it needs to stay in place. I take it this is still for your bar-ends / mirror fittings.
Cheers. This is what I thought.
