Bolts - buy from official sources (DS, CMS) or source them other places?

Hey all

When restoring bikes, do you usually buy new bolts from CMS or DS, or do you source them from any where you can get them? Can't figure out the best way forward. DS or CMS would be the most expensive way forward. Don't know if all their bolts are stainless steel etc. Many of my bolts are rusted through, and replacements have been made during the life of the bike. Looking to replace them with fresher ones, also to shine up the look a bit.

What do you guys recommend?

Talk to nurse julie, she has the proper jis screws, you do need a jis screwdriver NOT a phillips or pozi

The original bolts are plated (zinc usually) that has a role in corrosion resistance.

In the aluminium cases the zinc coating is sacrificial in that it's this part that changes to white corrosion and preserves the aluminium casting from being eaten away.

Stainless steel has the affect in the same conditions to cause the aluminium alloy to be corroded.  They need to be assembled with a sacrificial metal grease (zinc, copper, nickel types) to avoid promotion of this corrosion when used instead of original fit bolts.

When I rebuilt my 400 I used a small bottle brush dipped in Copperease to coat the thread holes as well as the stainless bolts.

There are some bolts available that use a small bolt head instead of the JIS cross heads. Not being a purist I used SS Allen key headed plus a washer.
A lot to be said for using the original design that Julie's sells.

When I reassembled my engine, I used Allen head bolts with copper grease. But I am in the middle of renovating the front forks, and need bolts for attaching the front brake, the wheel etc. They all seem like regular bolts, so just wondered if there was something to just sourcing regular stainless steel bolts locally and assemble with copper grease, or if using other bolts than from CMS/DS will have some sort of cosmetic effect I am unaware of as of right now?
