Acme thread nut

[AdrianLR]

Does anyone know where I can buy a 3/4" LH Acme thread nut in Australia for less than $40? For a jockey wheel on a boat trailer.

Alternative is to buy a whole wheel but a bit more mucking around to change over.

Could you get a scissor jack from the wreckers or auto shops for about  $20 should be the same threads on the screw blocks or a pair of caravan wind down O'L school stabilizer legs .. then it would be a bit of grinder / file time ..

Or try Newcastle hi tensile. They will sell over the phone and mail it to you. They seem to stock everything.
