People run the aluminum cheap ones all the time. You just have to religiously check them. But I wouldn't trust them. Steel, probably the safest way
I know this. But other sites swear up and down to use thread locked. Which confused me.
Please keep in mind just because other folks ( meaning anyone no matter who or where ) have a differing opinion on a subject doesn’t make them correct - even if they out number the opposition…
That being said there has been some very good advice given earlier and since it’s a safety issue it can’t hurt to add another plea for doing it by what is known as a “best practice “
Once thread locker has been set/cured it’s doing its job - once it is disturbed it’s done and must be disassembled thoroughly cleaned and reapplied to start over. Any movement of the hardware post initial torque is game over - it still helps but is not working as designed.
NOTE: I do believe that if a spacer is used it must be torqued in a star pattern in graduated increments followed by several verifications initially and rechecked periodically ( every time the wheels are off and at a minimum every six months depending on use, size of tires and type of application ). This means that a thread locker might not be the right choice on this type of application - thread locker is fantastic in areas that are in extreme vibrations or not easily accessible but you have the ability to verify the condition of the stud torque anytime and relatively easily and often ; so in this application it may not be the best practice. If thread locker is the only thing keeping the hardware from backing off than there is a greater issue !
Also mentioned earlier the studs are only designed for clamping force not torsional force but you could use a surface mount adhesive ( NOT a thread locker ) like Loc Tite 660 for added grip on the mounting surface of the hub to adapter side.
There will always be folks that never had any issues doing things many different ways on many different things but there has been some good advice passed on along by several folks here so please think about this application and use the best practice on these parts that are adding leverage and stress - it should require more attention and maintenance….
