Lug nut studs.

My bad, I was referring to the torque to install the new stud.

Ahh right

As long as the serrations align when putting it together, the new stud will pull in pretty easy. The wheel stud installer is around $10, so it's a cheap investment.

If you are really worried about it, grab a cheap 1/2-20 nut at the local box store and the nut will strip out and fail long before the good stud will. Of course, I'm not sure if you can readily buy Imperial (not the car) nuts and bolts easily where you are.

We definitely can, but not as cheap as you guys across the pond - you guys might pay 3-5 bucks for a pack of 10-20 nuts at Autozone or similar, here, for the same thing, expect to pay 6-10 instead (exchange rate taken into account).
That's exactly what I did with my old Toyota though. Used a sacrificial nut and a washer but forgot the oil. The nut was already starting to get chewed up after just two studs.

I just clocked some narrow gauge wire between the splines on stud n hub, rusted in place n that was 10+ years ago...... shrug
