I thought those "bolts" are actually studs that are pressed into the hub. The
unthreaded portion of the stud has splines which should prevent them from
turning when you tighten the nuts.

Subject: [Healeys] Rotor Bolts
My P2 BJ8 has bolts holding the front hubs to the brake rotors. I'd like to
check torque on the nuts occasionally (yearly), but the bolts turn. It
occurred to me that I could tack MIG weld the heads to the rotors on the
backside. I mentioned this on the Forum and a racer said he tried it on the
rear studs and the studs failed almost immediately and he lost a wheel. He
attributed the failure to the heat from welding.
Anyone tried this on front bolts? Recommendations for/against using Grade 8
(or Grade 5) bolts? I wouldn't want to gas weld the bolt heads, but it seems
to me MIG tacks would keep the heat more localized and not cause embrittlement
but, obviously, there are potentially serious possible consequences.
