Is this a 2 piece nut where the outer hexagon part is not threaded and simple locks into the 1/2 that seat into the wheel with a locking drive ?

Are they aluminium or steel ?

Hi Andrew,
My latest purchase arrived with these (no locks). Think they are aluminium - will check and let you know.
Cheers, Richard.

So arecthey in 2 pieces - a base and locking keyed hexagon top ?
They are described as longing nuts so they must lock or key somehow?

2 pieces - yes. (Mine are the part number you mention).
type911 description spells it out, I think:
"Old style nut that takes the lockable barrel type lock. Price is for one nut without lock"

The part I have works standalone as a nut: has domed part, thread to engage with stud, hex part for spanner, you know the sort of thing... but it's longer than a normal aluminium nut and has a hole in its centre.
I assume the locking part (different part) fits into that hole, and that when in place the lock part prevents our would be thief from getting a spanner on the nut.

I have these on mine. The out locking part/barrel with key slots over the nut, an expanding mechanism open and closed by a quarter of the key engages on the inside/hollow part of the nut.

So, just to ne clear, is the blsck aluminium nut in the link 2 pieces or one piece?
One of the descriptions above just implies that it is an extended open aluminium nut (1 piece?)

One piece extended open nut

Yes one piece, but part of 2 piece system. It doesn't spin or anything. It's the nut part of these. Barrel with a key in it slots over the nut covering the flats so you can't get a wrench on it. A quarter turn of the key releases the barrel/cover, exposing the nut so you can undo it.

Thanks guys, this has been very usefull
Cheers
