First time taking off the wheels for new tread. The lug nut pictured as B is what’s on the car. Is that the correct lug nut for the wheel or should it be the lug nut pictured as A ? Different shoulders/flang as I’m not sure which is stock for the rims.

Is bolt be the correct length? Seams about right as the hub of the wheel is fairly thick.

I forgot to measure the bolts

Almost 100% that my Pedrinis use a 40mm lug bolt

Bolt A has the correct flange (ball seat cup) and needs to be 40 mm.
Bolt B is totally incorrect.

Here is a more correct option. Factory bolts had 19 mm heads, these are 17mm.

Thanks for the help. I wasn’t sure if it was the same lug nut that used on the four spoke Fuchs or not. Sounds like it’s the same.

I’ll order the proper ones in black to replace the genky ones

Same for Mahle and Pedrini I am guessing?

Yes. Fuchs, Mahle and Pedrini all use the same 40mm lug bolt.

I believe the short ones are for steel wheels because they are not as thick.
