wheel nuts

Have the Thailand makers somehow made the nuts with an imperial size head ?

Don't know if the Mk 1 BT50's wheelnuts are the same as a PX 1 or not, but the BT's have a decorative cap on them which is easily damaged by a 12 point double hex socket. Use a single hex socket and they're fine. Standard wheelbraces and single hex sockets fit properly.

As your tyre fitter said, change them we some decent after market ones. Do it now and you won't be left frustrated on the side of the road. The standard ones on Ranger and BT are renowned for the decorative head being damaged.

Mine were butchered by the dealer and overtorqued, so I couldn't get them off with the standard tools. Lucky I discovered that in the drive and not the middle of nowhere.
The chrome cap only goes over the nut and is crimped on just clear of the clamping surface of the nut.

If you are careful with a cold chisel and a pair of pliers you can peel the chrome cap off and then get a good fit with a 18mm (I think) socket on the steel nut to get them off.

I was lucky and had 24 spare nuts that came with a set of rims I bought, but you are better off going and buying a solid set of wheel nuts that don't have the stupid decorative cap squished onto them.

wheel nuts thanks for replies lucky i found out before travelling ,new nuts from ford 30 dollars,after market i do not know the price,as the tyre shop gave me some

They are the same as the bt50 nuts which are a lot cheaper. Only use a deep hex drive socket and there will be no problems.

stupid me thought they were met to be like that .... lol ... but i don't have any problems with wheel spanner fitting etc but i will be changing them pronto !!
luckily i'v already got 2 sets of spares i got b4 my last trip away
thanks for letting us know about this problem...... cheers
