how many nm for dome nuts on wheel axle?

I don't know how hard I have been pulling them hitherto but my intuition tells me this was considerably harder. I read that Shimano recommends 260 - 290 inch pounds for axle nuts which is 28Nm - 32Nm. Excellent, thank you! Probably less on an alloy frame - I frequently have to file the drop out slots because I over tightened it and squashed it. |

Probably dome nuts look better but regular old nuts hold just as well :-) The saying goes that the dome will protect the threading of the axle, right? From what? Cosmic rays? vermin? zombies? I suppose if the bike falls over or strikes into other objects when people muscle it into and out of over-crowded racks. Perhaps dirt will find a home there rather than the more level dome... Most dome nuts are 2 parts pressed together, they can let water accumulate and trap. Corrosion can go un noticed. I like the suggestion someone made of SS nylocks, but I've never seen any with the right thread offered for sale - not that I bothered looking very hard. They use a lot of dome nuts on motorcycles and corrosion isn't a common problem - but its a PITA when it does happen. |

They use a lot of dome nuts on motorcycles and corrosion isn't a common problem - but its a PITA when it does happen. Automobile muffler clamps are an extreme corrosion situation, and the nuts that tighten onto the U-shaped clamp rod often can't be removed because the threads beyond the nut rust badly. Eventually, I learned to just install extra nuts to cover and protect those threads. That would work for bike axle nuts too, if it were really a problem. (Not that I've ever had the problem on a bike.) Drivel: last year I finally sold my dearly beloved Honda station wagon. It was only 26 years old. But not long after I bought it (used), I had to replace the muffler. My locally-owned auto parts shop said "We can give you a standard muffler for $XXX, or you can get one with a lifetime guarantee for 20% more." I went for the lifetime guarantee. It paid off in spades, of course. I probably got four free mufflers while I owned that car. But the first couple times I couldn't get the new muffler until I took the old one in to the shop along with the original receipt. Eventually, they let me take the new muffler home, install it and bring the old one in. I'm proud to say I astonished one worker by returning the old muffler in about half an hour, driving the car with the new muffler installed. Extra nuts on the clamps, anti-seize everywhere, and practice paid off. -- - Frank Krygowski |

Doug Landau wrote: switch to SS Nylocks n paint exposed threads with thinned linseed ^^ excellent advice ^^ Dome nuts are the original component. To get anything else would be impractical as there are so many such bikes around, and besides I don't see anything wrong with using dome nut and washers. Rather spend my $$ on Donuts |

Rather spend my $$ on Donuts I use lock nuts on things that are never removed, e.g. rack, fenders, stays, and kickstand. The wheels I stick with dome nuts and washers as it is the original component, it looks good and I have no bad experience with it. For the brake arm and chain guard which are also subjects to removal just M5s with a split washer and nut - if the chain guard stay have threaded, just the nut. But it is just what I do at the moment, I have dropped many ideas and habits and came up with new ones since I started doing this... -- underground experts united http://user.it.uu.se/~embe8573 |
