I have to swap my summer tires to winters soon. I usually go to a tire shop but I purchased a real jack and will start doing this myself.

I’d like to buy the following but I’m not confident after looking on line what I need.

Set of black lug nuts for a 2019 540 running stock rims. I have the thread pattern but are they a cone seat or rounded.

Set of wheel hangar pin guides for same car

Set of jack pads to fit BMW jack points. I have read it’s better than the pinch weld.

Lastly what is correct torque spec for the lugs. I have a torque wrench but don’t know the specs.

Thanks

Jeff

Your factory lug bolts should work fine for both summer and winter wheels, assuming you aren't using spacers which require longer bolts. I stopped swapping wheels when my G30 came with AS tires, but prior cars always used factory lug bolts for summer OEM wheels and winter aftermarket wheels. Torque is 140NM or 101 ft-lbs.

As for jack pads, yes they are recommended and the raised center section should be tall enough that the outer edge of the plastic doesn't rest on the jack pad. It's not really strong enough to bear the weight of the car.

From the front jack point, I've been able to raise the car enough with an aluminum race jack to put a jack stand under the rear jack point on the same side of the car. This makes it quicker to change both wheels on a side with less jacking.
