@XyphoidProcess That's the ideal setup. I did have a look to see if I could buy M1.7 bolts on their own somewhere. The best option I could find online was a sack of 500 direct from China - even less reasonable than the mixed box I ended up with. Meanwhile, the town I currently live in is so useless that I couldn't even find screen cleaning wipes in any shops in the town centre. That's what's "killing retail" (well, that and sky-high rents), not online shopping.
