Need a bit of advice on threads..... I want to attach an item under the rear of my car (BMW) and found a long bit of spare 12mm thread sticking out from a bolt holding the rear silencer that would be ideal.
Anyway, with great difficulty (age and shingles!) I managed to just about get at it to screw a nut on but the nut only just got started and then went tight. In my complete ignorance I thought it was just a bit rusty and got a bigger spanner and went at it with all my (reduced) might but no good it would not tighten.
In a flash of inspiration I realised it might not be a standard 12mm thread so I sent for some 12mm course nuts! They came today and it was then I realised I was already using 12mm course nuts!
So now, after a google search, I need some 12mm fine thread nuts but there seems to be two types..fine and extra fine or 1mm or 1.5mm thread...oooer...which ones do I buy next anyone???
