Castle Nuts wanted

[STDDIVER]

 I am chasing  a few castle nuts zinc coated M 28 x 1.5 pitch.  These are for a MFK modification to the towing hitch to improve the articulation of the jointed adjustable tow bar.   Any one know of any?

I'd be appreciative if any one has a couple or knows where I can find them.

Update to the last - Part No required - 01.03.01   Supply No 5430-66-123-2994   factory no P. 02258  and the dimension is incorrect in the CER as the nut is 27 mm x 1.5

Any help greatly appreciated!

They have been great in my stainless steal fastenings change over/rebuild needs for the entire Perentie.  I used to take sandwich bags of nuts and bolts screws etc. in with the number that I wanted written on it and picked it up the next day. No minimum order you can get just one of anything if you want. I've got neatly 5 kg of fastenings swapped out sitting in kerosene.

Thanks Phil - Have been in contact with these guys,  nuts priced @ $84.70 for 5 only 20mm nuts.  27mm nuts are WOW $ - but have found another source and far, far cheaper!   

This was really hard to place, It pays to shop around!
