Cam locks come loose on bed frame: imminent disaster feared!

[HappyJoe]

I have a solid wooden double-bed frame from John Lewis that is held together by two pins and associated cam locks (nuts?) at each corner. After some years - so no guarantee - two of the cam locks are getting loose and do not hold their newly-tightened state for more than a few days. I replaced an original as it was a bit damaged with one from Ikea (a bit smaller but still serviceable) and it is still loosening as before.

Is there any way to stop these things loosening? A sort of LockTite for wood would be nice!

Or a very reliable alternative way of fixing the joins that can be disassembled, if needed ?

I've used these before, available in a variety of sizes, any builder merchant should stock.

Thanks for the response!

I would have, but John Lewis said they were out of stock...

Herewith (I hope - I've not used this system before, I think) are 4 shots of
1. the bed frame corner, showing the latest fitting in situ.
2. the frame corner disassembled, showing the two cam pin fittings which are Allen-key-screwed into the frame
3. the pin. It's OK.
4. the cam-lock, showing how it is distorted wider; probably a factor in its easy loosening.

I have screwed the pin seats in further in the hope that this will exert a bit more pull on the cams when locked. (Might just splay the cam locks more quickly!)
Also moved the bed-head up against the wall to reduce movement.

It would be nice to have a rigid frame but I think the cam-lock system won't let that happen. Unless you have some ideas...

the way i normally fix these assuming theres enough meat
is on posts 2 to 3" thick i use 1 or 2 5 or 6" no 12 wood screw
or less than 1 1/2" 4 inch screws should do

washer on the head off the screw 5mm hole throught the post 3mm pilot in the rails

I'm also having this issue and finding it impossible to get the correct replacement cam locks did you have any luck ?

It's a 10-year-old post, start your own.
