Big difference in torque values for different stems?

    Pinno, winter bike or not, stop being a cheapskate and buy some new bolts. That looks 'orrible as it is and you should be ashamed :D:D

    The whole thing needs tlc. Most of the bolts are like that. I'm still alive. :D

    Stem bolts are chrome/nickel plated. You can buy stainless steel or titanium ones, if you wish.

    Bungle - don't go anywhere near 10Nm with the new stem/steerer or any future stems/steerers.

    Just checked my stem bolts (with a magnet) Tioga - all stainless
    Ritchey- all stainless
    Planet x- all stainless
    2x Deda - all magnetic so probably chrome plated steel.

    Other stainless ones- bottle cage bolts, Shimano crank arm pinch bolts, some seatpost clamp bolts, Ultegra caliper bolts, stem topcap, all spokes (which are actually bolts) mudguard hardwear . See there are some stainless bolts on bikes.


    Not all stainless is non magnetic, so can't say 100% that magnetic bolts aren't stainless but probably are not.

    Maybe I shouldn't have said "nearly all bolts are stainless" rather many bolts are.

    I don't think anyone ever claimed different. At least you've gone from 'nearly all' to 'some', which is a step in the right direction, I suppose...

    Except for the 'silver' ones I checked earlier, including rear mech mounting bolt, cable clamp bolt, limit screws, saddle clamp bolt, seat collar bolt, front mech mounting bolt, top cap bolt, stem clamp bolts, bar clamp bolts......all non-stainless. They're still silver though.

    BTW - spokes are not 'bolts' - but I expect that's a whole new thread... :roll:

    ...and the plating can make them seem less magnetic. How strong is your magnet?
    ...and we have no idea of the grade of stainless steel.

    Strong magnet. Spokes are bolts just long and thin but still threaded with a nut/nipple .

    I think you're just trolling now.. :lol:

    A 'spoke' has its own definition in engineering, which differs considerably from that of a 'bolt'. But again, if you can evidence your assertion, I'd be glad to read it.

    If a 'spoke' is a 'bolt'.......then a 'bolt' must also be a 'spoke'...

    A bolt:
    Definition- long pin with a head that screws into a nut, used to fasten things together.

    A spoke connects the hub to the rim

    What is the OED definition of ‘spoke’..? Maybe post that up as well... :roll:

    Leave out the pathetic insults and just post up the meaning..? Makes you look like a sore loser otherwise...

    A spoke isn't a bolt, FFS. You lot can debate the rest til your hearts are content, but I'm not having a spoke being a bolt.

    I don’t understand what the argument is all about, stainless steel is resistant to corrosion to a much greater degree than other ordinary or carbon steels.

    The level of corrosion resistance is dependant on the materials used to make the steel. In bike applications the two most likely causes of stainless corrosion are galvanic (quite possibly from rain) and pitting due to chlorides. Winter riding obviously sees chlorides in contact with your bike and sweat from turbo sessions is frequently left to do its thing. Bolt screw nuts call them what you will, they’re going to corrode.

    Here endeth the lesson.

    End of debate.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    A bolt has a plain shoulder, a screw is threaded right up to the head. But to call a spoke a bolt is stretching things somewhat.

    If the thread is stretching that’s waaaay too much torque :)

    Well if you want to make a spoke out of a bolt :lol:

    but surely the final torque settingl depends on whether the bolts are greased or not?

    Anyway, OED is hardly the best place to go for a definition on anything to do with Engineering.
