Hi There,

I am upgrading my front brake system on my 2007 GTS 250, and wanted to find out if anyone has found a polished steel option for the brake rotor bolts? I am upgrading to the Brembo Caliper and the Zelioni Type 3 rotor. With such a nice finish on that rotor I'd like to find an equally attractive rotor bolt.

I know pro-bolt will happily sell me 316 Stainless Steel set, but I am leery of the material strength. link: https://www.probolt-usa.com/stainless-steel-disc-bolt-dome-m6x20mm-xs-front-pack-x-6-ss6discfb620xs/

There is the grade 5 titanium option:

* the head of this bolt is 5mm tall whereas the OEM bolt is 3mm tall, would there be clearance issues with the 2mm difference?


I don't mind the extra expense of the titanium if a steel version cannot be found. I just wonder if the grade 5 titanium is strong enough to use.

I ride spirited, and at times with my wife as a pillion. I am not one to sacrifice safety for vanity. If great looks can't be achieved with safety in mind then ugly unpolished steel it is.

Any advice is highly appreciated.

*as a side note I did upgrade the suspension system to the sip kit as the stock shocks started leaking at 25K miles.


Thank you,

ride like this and stop worrying https://modernvespa.com/forum/post2530382#2530382

the stainless fasteners should be more than adequate. PB sells them as replacements for the specific application so I'd buy with confidence.

personally, I don't care for stainless fasteners so I can't speak to the aesthetic component but 316 is plenty strong.

I'll bite. Why don't you care for stainless?.

Thank you greasy125 for the confirmation on the 316 stainless. Why are you not a fan?

frankly, I just don't care for how they look. I'm not anti-bling, but I just like coated or stock hardware.

some of cheaper quality stuff has poor engagement with tools, like the manufacturing is just off enough that things strip super easy-- allen heads seem the most common, and by coincidence also tend to be used mostly in brake hardware that is always tight as balls and usually has a thread locker too.

I agree with your post Greasy , so many times I've rounded the hex on a countersunk head screw and ended up having to loosen it with a centrepunch and hammer and this on a hi-tensile screw . Using stainless screws is not advisable in my humble opinion , the hexagon is too soft to take a lot of torque without " rounding off " .

I dislike them only because drilling a broken SS stud is a pain.

Buttonheads & flatheads are problematic, allen the worst, torx much better no matter the material

frankly, anything stainless is just a pain in the ass.

the: I broke my rack or a crack in a pipe or broke off bolt- NBD get out the mig.

oh it's stainless. *groans loudly* goes to get the TIG *drags feet* sets everything up *sighs deeply* fineeeee. it's fiiiiinnnnnneeee.

10min turns into 2hrs.
