Wheel nuts

[stonedrive]

Hello everyone, l have just noticed that one of my wheel nuts is different from the rest,l have alloy wheels and have wheel nuts that have a concave top l think that's the right word for it or maybe inverted dome.Are the nuts different between steel and alloy. If so would anyone have a spare concaved one so they all match. Willing to pay.Many thanks Steve

I suspect the concave one is an original alloy one, and the others are replacement steel ones. Old alloy ones are prone to stripping their threads, so I would advise that you replace any you still have, with new steel ones. They will probably match the ones you already have.

Hi Mike, sorry my post is probably not very well put,all of mine are concave apart from one odd steel one.would it be best to change them all to steel. Are steel and alloy ok when put together or would stainless steel be better. Many thanks Steve
