Just get ready for "Bill shock" when you get the good Proti stuff. It is beautiful but the most expensive I think. I have spent way too much money on it on my 1199S. I also recently made a big order for the engine bay in my car.I’ll definitely have some questions when I’m at the titanium stage. Thank you very much for the info.
Six or seven years ago I used a different Ti bolt in the front calipers on my 1199S. I was still learning from experience and did not put enough anti seize on one of the bolts. That brand used tapered Cap head Hex. I used a gold colour and later decided to change to a silver polished Proti, (It is all now silver polished Proti) anyway when trying to remove one it would not come out and I twisted its neck off. That then leads to the very labour intensive drilling out of the old Ti part left without damaging the caliper. This took me a long time. It has only happened once but the calipers produce so much heat and without the anti seize in there they may lock themselves in. I had carefully done all the threaded portion but not the non threaded part. Now I do the whole length of the bolt and no problem since. You will see on the Proti site that Sherman particularly mentions the difference at the neck of his bolts and how they are forged.
I whole heartedly agree with H that the Torx seems to get a better grip on the bolt especially if you use the correct Torx tool and it is good quality. I use "Hazet" I have also found that sometimes when you are in a hurry you think the Torx size is the one as it fits but sometimes the next size up fits better. It is easy to use an undersize one when you are in a hurry. I have done it a few times when pressing on late at night.
