Does anyone happy to know what the thread is on the flexi brake pipefemale brake union as I want to get some thin nuts to hold the flexi secure in a little bracket I have made up.

thanks,
Rich.

Usually M10 x 1mm offset

IFAIK the thread is a bit special and I don't imagine there is a tap/rollers off the shelf. Maybe a small subcontractor with a CNC lathe could produce a bundle of them.

I've even thought of buying a CNC lathe meself to produce a few bits.

10 mm. fine (1.0 mm pitch) Just bought some myself for exactly the same job.

Just to confirm (if it needs it) 10mm fine.

Bought some 2 weeks back from BBN Fastnet.

Just a small bit of slightly relevant info. here.....

Unlike most of the inch threads where there a coarse and fine range, in metric there is usually a standard thread which is coarse and usually more than one fine thread, so it is always best to add on the actual pitch to the size (as Mark and Geoffe did) although only one fine size is considered standard, in this case the actual listed standard M10 fine thread is a 1.25 pitch........so although the M10x1.0 is very common it is not the standard fine thread usually listed....

All according BS 3643: Part 2: 1981

So the moral is, to be absolutely certain specify the pitch too..........

Hmm.....I think I need to get a life...

I have always known metric coarse to be known as standard,anything less(10x1.25) as fine,and something like 10x1mm would be referred to as superfine.
A common fix when stuck for locking nuts is to cut a brake female end down to size.

i have stacks of these nuts to hand mail me offlist and i'll send you some.

Alan,
I did say referred to! Don't know the exact answer to your question on 8mm threads,only been in engineering for 24 years so I dont know everything.
I've personally always referred to anything less than a standard fine thread as superfine..

All the best DEAN.......
I'll have to blow the dust off my old books from all those years ago at tech college ....

Hi Dean...yeah about that long myself......old gits aren't we...?

The gist of what I was saying was (and I'm sure you'll agree).....it doesn't hurt to include the pitch when spec'ing metric fasteners/taps etc...

I hear you about the dusty old books too...
