Measure your lug nuts (yes, lugnuts!), please?

[JKav]

This might sound like a strange request, but can someone confirm whether their stock lug nuts have the geometry shown below?


It is an open-top lugnut with shank and washer. Toyota used this a lot... but I don't know on which model car. I think its Lexus SC300/400 and LS400 but I want to be 100% certain. Can you help?

from my personal experience, it seems that the nuts with the open tops, were used on cars with alloy wheels, that have a large plastic cover that covers all the nuts. Ones I know off the top of my head are SC300 w/ 15" wheels, 90+ LS400 (not sure what the last year was of covered lug nuts), ES250.
If you're running long studs and that's why you wanted these nuts, the top of the covered nuts usually pops off with little trouble, as it's just a thin piece of metal.
