Wobble bolts

[SlimDubs]

Just bought some Mini Lites off a mate for my 6n (will get some photos up soon as it looks pretty sweet)

They're on the car at the minute and seem to fit fine but I know i really need wobble bolts for safety!
Just wondering will these do the job?

Don't wanna get 'em and they don't fit the in the hub or whatever... Not sure about all the sizes

Thanks
