This is what I found for removing studs, the allen keys are only used upon installation. Removal tips: • When removing studs do not use the allen as doing so may damage the stud. Thread two nuts on to a stud and lock them together. Then use a wrench on the nut closest to the hub to loosen and remove stud.

I think Harold is saying that the RB studs WON'T strip like the typical allen key driven studs when removing. A simple 8mm hex socket will do the trick.

So, if this technique is used by all either for removing or installing, allen key or hex head becomes unimportant??

So with allen-ends, do you use them at all for initial installation or is it still recommended to use the double-nut method?
Also, am I correct in thinking you install the studs dry, torque to 40-50ft/lbs then still use the standard 88ft/lbs on the nuts? |

I believe some manufacturers recommend low torque e.g. 16 lbs + 1 or 2 drops of loctite. Others recommend dry installation 40-50 lbs.

Obviously you can always double nut. It's not hard to do, but you sort of need to know how to do it right, or at least watch someone do it once who knows how to do it right to do it right. Allen key and hex head takes all that out of the equation. To me, the key features are still the tensile strength of the studs and the finish on the studs. Allen key or hex head is a nice feature to have. Bulleted thread is a nice feature to have. If the studs you're looking for meets the tensile strength and the finish criteria, and are priced competitively, I'd go to the next two features and use that as the deal breaker.

But be sure you get the RIGHT loc-tite. There are multiple grades of "red" and "blue" and they all have different properties. For example, the 262 commonly found at autozone or pepboys are not "permanent." They're high heat, high strength and provide and approximately ~40-50 ft-lbs of break-away torque without the actual stretching of the fastener to achieve that torque. Clarify with the manufacturer which specification thread fasteners they recommend.
