Hello everyone.
I am using Zipp Service Course SL stem with 120mm and -17 degrees.
The bolts I am using now are the stock ones, which have T mark on it, I guess they stand for titanium, have worn on the heads a bit.
Before it is too late to replace them, I want to buy new bolts with T25 heads and change.

Do you guys recommend me some bolt manufacturer to change it, or all Titanium screws will be the same regardless to brand or origin.

Also while I am changing the bolts of the stem, I want to change seatpost clamp bolt to titanium too. But I wonder if it is safe to use a soft material like titanium there.

Seatpost clamp bolts are fine to change to Ti. Normally, any place where you are using a steel bolt on a bicycle you can sub in a Ti bolt with no issues.

Avoid using Aluminum bolts in single sheer or any high stress points. Bottle cage bolts are about the only place I use them on a road bike.

There are quality differences among Ti bolts. I would not use anything from eBay. I get mine from
My favorite components are the ones I never have to think about.

I bought Ti bolts from the far east to put on the stem on my winter bike once the original steel ones had started to corrode. No issues with them at all.
