I have some DT Swiss 140mm twinshots with their 15mm bolt thru.
They are ace, except the 15mm bolt thru bit on one of the legs keeps coming loose, so the disc brake doesn't align up.
It looks like some proprietary (sp) pattern type thing is required so I can tighten and get some thread lock on there. Anyone any idea where I can either borrow or buy one?

The gold bits in this picture are unscrewing from the white fork legs.
Some sort of pin spanner would do it

Long shot but would a cassette tool do it ?

hadn't thought about a cassette tool - although I suspect the diameter is too far "off" - I'll investigate tomorrow.
I'll order the pin spanner if the above doesn't work and see how it goes. Just slightly worried about damaging the gold bits.
I've been using a half coiled bungee to tighten up so far (fold over, ram in gap and twist into position) but that's just normalising the problem.

Used one of these the other week to do the same job on a new pair of forks - or simply ask your LBS to do it as its a one-off
Yep pin/peg spanner would do them up.
Hydrospanner
looks like a bloody big torx might do it
I have a T60 which is about 13.5mm outer diameter
Guess you want maybe 17mm outer. No idea if they exist or whether there's a chart somewhere to tell you what number it'd be
Addit: [url= https://en.wikipedia.org/wiki/Torx ]https://en.wikipedia.org/wiki/Torx[/url] T80 maybe ?
Looks like the sort of thing that I would usually bodge some sort of tool for out of whatever was to hand. Probably best just buy a peg spanner as suggested above though.
Many thanks to people suggesting the pin spanner - it's ordered.
LBS said he didn't have the dtswiss tool to do it and that tbh it wasn't worth him buying it just to do a 1 off fix for my forks (which is fair enough) and showed me how to tighten it up each time but that's getting on my nerves now.
He's a bit of a hike to get to, other bike shops sell bso's and the like until I drive over an hour away to get to a proper decent place.
Great to know someone else (dovebikes) has done the same.
Many thanks all!
If you really wanted to bodge it, you could just use a screwdriver as a drift and then hammer them round...
I really don't fancy bodging the last set of 26" straight steerer xmm140's in Europe because they match the bike exactly.

Might want to fit them the right way round....

Seatpost's a bit low.
No, it's the new 10" Reverb.
Yeah, I do get a bit of stick for saddle height - it's just comfy like that, any lower and my knees feel like they are going to pop.

I think I'd try a very large "screwdriver", 18mm ish wide, so that it would fit in diametrically opposite pockets. While I've never seen a screwdriver that wide, it would be easy enough to make one - file down the edges of a bit of flat steel and hold it in an adjustable spanner or molegrips.
Definitely not a cassette tool. Pin spanner may work, I'd be tempted to try strap wrench on the outer edge though. Certainly none of the stuff in my tool box fits the one on my fork
Have you thought about using a large hex head socket - i.e a 20mm (or whatever it is) allen key?
Failing that, hold a large bolt by the threads in a set of mole grips and pinch it up.
Was going to suggest similar^^^
Find a bolt where the head fits the hole but won't spin. The better the fit, the better it will work. Now thread 2 nuts onto the threads of the bolt and using 2 spanners tighten the 2 nuts against each other. et voila. You can now turn the outer nut while the bolt head is in the fork and it will tighten the insert. I use the same method for removing odd (large) size hex fixings like on the XT freehub.
Can't you use the qr/axle as a screwdriver? I've no idea but if it fits the splines then it might work? Maybe with some mole grips wrapped in inner tube to protect it?
This may be entirely off the mark but I was recently struggling to do up my Middleburn crank extractor bolts and just before ordering a pin spanner I tried my chainring bolt spanner and it was perfect. One of these, you might have sat in your tool box:

I like welshfarmers idea - I'll give that go tomorrow (I just need to sneak the bike into the workshop), if not fingers crossed the pin spanner will work.
