Just noticed one of the leg hinge bolts on my Tactical X Compact bedchair has lost it’s nut, I don’t suppose anyone knows what size they are, I don’t have any callipers?

I don't know but safe to say 5 or 6mm. Go into a local fixings company and you will probably get one of each for 50p

If it's not a royal PITA then you could take out another nut/bolt - then go to your local hardware store (as Paul suggested)
They can test to see what fits from their stock (or you could do the testing if all the nuts/bolts are on display in an aisle)

Something that needs to support bodyweight might be M8
M = Metric
8 = mm

I tend to find most 'stuff' is M6 or M8

If it's a new nut you need then you could get the nylock version so that hopefully it grips better and doesn't wiggle lose.

If you still have the bolt just take that to somewhere like b and q and have a look in the pick and mix section.

Just checked mine.
The bolt is 10mm head size so 6mm thread.
Only just long enough as it is with a Nylock nut.
Might be worth getting slightly longer bolts with nylocks if you just have standard nuts on at present

Thanks for the info chaps, most helpful 👌

You were spot on by the way, they are M6, all sorted now, cheers 👍
