Try www.rdgtools.co.uk.
they have a vast selection of weird and wonderful things and always excellent service and reasoanble prices

Try Tracy Tools as well. Always excellent.

Steve make sure you are not looking at an M16 x 1.5 metric fine tap, from our discussions you need a non standard Acme or ISO metric trapizoidal thread form.

Can't you just screwcut the nut on a lathe

Thanks Jason, I have not got a tool nor have I tried screw cutting yet, I will as friend is going to teach me. I studied the thread further and the only gauge that fit is as above, I have ordered a M16 1.5mm RH so will tried first for y axis, I noticed that the drill taping size size is 14.5mm but the hole size is 15mm ID and 16mm OD so they (Far East) could have use a 15mm dill to get flat threads. To be honest, I think I will have to cut a tread, I'm just being impatient and look at easy option first. plus another tap for my collection.
