When I ordered my sills I ordered the bolts from BMW as well, if I remember they sold them in bags of 10 bolts.

Thank you for helping

I would get the plastic fasteners for the plastic trims inside the doors too as these need to come off, they have a tendency to snap when removed

When I removed the cover sills on my Z3 I did replace some with BMW screws obtained fom Sophers at Lincoln using the forum discount, would use the stainless ones if I were to do it again.
Oem shows size of the screws as 4.8 x 16

I just purchased a pair of outer sills plus a whole lot of screws clips etc for my M Coupe (they will be same as roadster) cost me £331. Didn't realise that Vertu who took over Cooper's dealerships where only giving half the discount that Coopers used to give.

 

[Paul H]

I didn't ask for a discount, I had no idea they'd do that.

Thank you everyone for your help

It would help if you were careful when replacing thresholds. After dismantling the thresholds, remove the sharp metal notches and cut off all remaining elements. The inner part of the threshold is processed using a grinding machine, which can completely remove the foci of corrosion and damaged paintwork. Also, processing using a rust converter will not be superfluous. I also replaced the bolts by buying new ones at Scrooz. Otherwise, you risk losing a new part due to old rusty bolts. All actions must be performed as accurately as possible, precisely fitting the part to the mating parts, thereby ensuring the rigidity of the entire structure
