Thread: 1 and 1/2 wheel nut away

They used to be quite common even on cars, but this is probably why they stopped fitting them to light vehicles where the studs were small enough to break fairly easily.

Hi John

I'm wondering if there are any vehicles being built today, that still use LH threaded wheel studs?

Cheers Arthur

Weren't Valiants, or at least some models of them fitted with LH threads on the left hubs and RH threads on the right side ?

It used to amaze me on the old corrugated Stuart Highway to Alice Springs, the amount of rims along the roadside that had become loose with the vibrations, then flogged the stud holes right out before parting company with the vehicle.

Cheers, Mick.
