Help! Thank's. Mick. The socket size is 3/8w. These images might help and they show the difference between the original nuts and the new ones currently available from JRW. I have replaced all mine and they're fine but "dig" in more to the nut recess because the shadow profile is the same shape but shallower on the new nuts so the flats start to bear on the recess sooner. I don't know about any other source of wheel nuts but I suspect the profile will be different than original and I haven't ever seen NOS available. Too shallow a profile might be dangerous.  |

I would be wary of stainless steel nuts. I see this advertised usually as for show use which would suggest they are not suitable for normal road use. I believe the tensile strength of stainless is relatively low. Perhaps someone could confirm if I am right.

I think the main problem with stainless steel nuts and bolts generally is that they are much harder that ordinary carbon steel, and the threads tend to bind. Stainless on stainless is worse.
I think the problem is that if you did them up tight, you may not get them undone again without breaking the stud or damaging the thread. The binding action is called galling.

the chrome nuts tend to peel at the edges very soon if used every now and then. next time i possibly prefer stainless steel.

Galling is a problem Warwick if the threads are tight ::)but can be avoided if the threads are lubricated slightly with Copaslip  Nothing wrong with SS in the compression mode you just have to be "careful" if used in the shear mode  best avoided if you aren't aware of what the grade properties are! |

John, I'm also forgetting that stainless steel bar stock probably comes from China these days.

John, I'm also forgetting that stainless steel bar stock probably comes from China these days. So are possibly the chromed wheel nuts. No proper layer build up in professional terms I would say. Galling is an interesting point so lubrication will help. Good advise... |

Thank's everyone for your replies, i have an idea that mini nut's might fit, i hope so as they are only £1 each as apposed to JRW's £3.50. |

Proper minis (not the BMW contraptions) have 3/8 unf wheel nuts. Be a bit careful of ordering from a couple of places on ebay,who according to their listings seem to regard imperial and metric threads as interchangeable.
