71177B means bag rather than a blister "clamshell" pack of 4 if my google info is correct!
So a bit lighter for shipping.
Depending on where you are in the world,or who you know,I would go for the Gorilla automotive products Acorn lugnuts type 71177 and 7/16".
They are great quality and can be had at a very good price per pack of 4 or as a job lot of 20 deal by some suppliers.
I got 40 nuts for £55 direct from the USA via a mate who was there.
USA car parts suppliers worldwide should stock them.
