Correct, they act as an extended wheel stud.
<<<<<<<<< Thats my lad there, he uses 2 inch ones on each side.
Loctite them to the studs in the hub, and use lug nuts at the wheel.
The Loctite stops them coming off when you remove a lug nut.
They work pretty good, we aint broke one yet and my lad flys a little bit.
