Honda titanium panel bolts
These are titanium panel bolts for a Honda, they are tapped M5 down the shank. Tapping titanium is always fun, you just never know when its going to snap the tap! The smaller the thread the more buttock clenching it is, because its such tough stuff smaller taps often don’t have enough strength in them to cope, which is why you have to use best quality taps that are really sharp. The main danger areas are running too far down a blind hole (but any metal will snap a tap if you hit the bottom of the hole too hard), and coming out. It generates a fantastic amount of heat when you tap it so it tries to grab the tap on its way out, i often leave it to cool before withdrawing the tap.
