W221 Lug Bolts

Trouble with the flower head ones is that some shops use 17mm sockets on them which, whilst they will get the job done, they don't fit properly and damage the bolt heads... Better to fit the standard bolts and not worry about it although the flower bolts do offer a degree of anti theft protection.
You need to get the correct length though, too long and you'll tear up the parking brake fittings on the rear hubs, so would recommend MB sourced bolts over aftermarket.

The wheel nut wrench for trunk that Mercedes specifies for cars fitted with the flower bolts is a standard 17 mm hex, and therefore that's the correct wrench size although it doesn't mean there won't be damage, especially with impact tools.
I try pretty hard to avoid generic tools and consequently have a German Hazet socket for flower bolts and experience no fit or damage problems using hand tools. In addition I have a nice German Stahlwille torque wrench sourced through the Mercedes parts system, which is unique in that it does not require zeroing and is active in one direction only, meaning same wrench removing and reinstalling bolts. The ratchet head is removable and reinstallable in other direction for those right hand thread applications.
they get beaten up by morons in stupid garages

I forget where I saw it recently, possibly Vice Grip Garage, but apparently, you can order genuine parts from a reputable seller via Amazon, but Amazon will fulfill your order from central stock rather than with items provided by the seller. So there's a very real chance of receiving any old knock off tat even though the seller you purchased from supplied genuine parts to Amazon.
Not that Amazon would give a flying monkeys if all your lug bolts snapped. Probably just refund you the purchase price and pass the blame back to the seller🤐 And people wonder why the world is so messed up.
Apologies for the rant😳
If I ever go to Hong Kong, unlikely by choice, then I will visit the sellers address so you can see exactly where they came from.

the wheel hub of 18" x 8.5" ones are massively thicker and stupidly heavy - and required much longer bolts
the little ones I show are of the better to drive 17" x 8" wheels that used to run 235 55 17 tyres - the car almost rides correctly when it has tyres - and were the original size when the car was first launched - trouble is they look so silly
