I've seen suggestions on putting in wax, solder, and gluing ball bearings into the head of the different allen bolts on the bike, but I'm hoping I could get something that looks a little cleaner without getting ridiculous. I'm thinking replacement bolts on the seat collar, maybe the seatpost bolts, the handlebars, the water bottle cages, and possibly other bolts for other parts.

I understand companies wanting to deal with quantities, I'm open to that and paying a higher price for smaller quantities. That's all a given to how things are run. I'd just like to start finding the crap! The closest I got was metric security bolts with button heads. I'm looking at mostly M4, stainless steel, socket head in various lengths. Some M5s too.

Any sources for these bolts?

Thanks for reading this and I'm open to any and all suggestions on curbing this problem.
