since my brakerotor bolts is 34 years old they tend to rust and get ugly very fast after riding in the rain i needed a fast way to make them shiny .
I found making a casting of the screw with epoxyputty and a dremeltool worked well.It now takes 30 seconds with some autosol and a little paper inside the socket
to get them shiny
Awesome idea! :good2:
Update : The polishing tip is not so good because the bolts will start to rust again fast :flag_of_truce:. I got tired of trying to keep them rust free i even
painted them with clearcote to se if it held the rust away ,but it did not last for long so i finally had to bite the rotten apple and buy new bolts .
Titanium bolts arent THAT expensive when its what holds your brakes together.
Stronger than stainless and corrosion resistant to a very high degree.
Wherever i can im swapping to these as the salt on our roads takes no prisoners...

Embrace the patina, just accept and move on, those bolts not match the hub patina :boredom:
Im not impressed with the bolts i bought from yamaha dealer, they got a strange light bluish shine.I have after i bought them found that it was possible to buy stainless steel bolts on ebay
they vould have matched the stainless rotors ,but stainless screwed into aluminium will seize so then i will have to add antiseize on the bolts.I used
akrapovic bolt sealant as loctite. It is not so important how tey look anyway better than the brown rust =). Next up is the spacer and axlecastle nut and some other screws that rust after som rain weather.
Unless you're planning on restoring or keeping the bike showroom standard then stainless steel fasteners are a no brainer, M10 x 1.25 are a little expensive but for M6/8 you can buy a handful for under a tenner (UK)
As for UK riders, Screwfix sells packs of common size cap heads cheaper than you'll find online and they're open 7 days a week
As for shouldered bolts on non structural parts I've used 8mmx1mm wall aluminium tubing on M6 bolts

Yes i found out later about stainless steel bolts and they vould have had a better color match ,but it is a little drawback and it is they seize in the aluminium
and if not covered in antiseize sealant it is easy to damage the treads when trying to get them out. The bolts i bought at yamah was expensive so not going
to buy more bolts :smile:
I have *never* had a problem with my stainless steel rotor bolts in any of my FJ's.
I have had a problem with those butter soft oem Yamaha bolts stripping the hex Allen threads.
The harder SS rotor bolts are superior to the oem.

Im not saying it is somthing wrong with installing stainless steel bolts into aluminium ,but that is if you use blue locktite or other sealant on the treads
if not there is a risk that the treads will cold weld toghether especially if moisture gets in there wich it does if not using some sealant on the treads.
If i had found stainless steel bolts before i bought the oem bolts i had bought them instead.
I know the hex allen can be rounded and make a mess so i use a mini torch to heat the bolt first then a good quality bit that fits snug and a longarm wrench to get them out. All 18 bolts came out without any problems just start slow and the bolt must be hot.Here is a pick of what i used
And if anyone needs to know the bolts torque is only 20 NM and with blue locktite
