Cooker hood - Nut problem

[spookly]

I've got a Baumatic F90-2SS cooker hood, and about 6 months ago it decided to lose a nut and the impellor broke.. specifically the plastic sleeve that fits around the rotor.

I've bought a new impellor, but can't find the nut that secured the impellor onto the rotor. It appears to be about M5 in size, and is left hand threaded. I can't seem to find anywhere that stocks left hand threaded nuts in anything below M6 size... any ideas?

I can't find a parts list for your hood but the place that supplied the blade may be able to supply a nut.

Had a look at the parts list and for some reason it's called a screw, nuts if you ask me. Anyways, part number is SYS020.
All you need do is find a supplier.

Thanks for that. I'll try and track down someone who stocks that "screw" then...
