Ti Bolts for bike?

[Gerry Attrick]

As I said, I have used Dave Middleton for stainles fasteners for donkey's years including countless fasteners on large motorcycles. I don't willingly risk my neck. Have no fear, stainless is more than strong enough for cycling applications.

rather depends on the thread quality of the bolt and frame ....

I've twisted the head right off an socket head M5 bolt made from A2 stainless, just by giving the long 4mm allen key a bit of extra welly.

buy a torque wrench (please)

for my titanium frame I bought bolts from here

A dab of grease on the threads of a bolt, prior to assembly, is a good idea for several reasons.

316L (low corrosion version, resistant to chlorinated cleaners, if you can get this to rust on a bike you park it in a bleach works.)

The L stands for low carbon - which means that it is weldable without all the corrosion resistant chromium being hoovered up by carbon atoms.

I would have thought pretty much any grade of austenitic stainless would be good enough for bottle cage screws and the like.

As already stated on here, for load carrying applications then austenitic stainlesses don't have great strength.

There is definitely no need for titanium fasteners.

The only reason I considered Ti was for anti-rust tbh.

Just seen these and wondered if they would be suitable: http://www.screwfix.com/prods/16785/Bolts/Socket-Screws/S-Steel-Socket-Cap-Screw-M4-16

I would say so. It's a bike that occasionally goes out in the rain and sees a bit of road salt every so often, not a chlorine dioxide tanker. They cost how much? £2-odd for 50? Sounds like a bargain to me, and if you can break one using conventional hand tools then you need to be less brutal.
