These came from an old folding garden chair I want to make some copies of, there's an unthreaded section at the end which slides in a groove when you fold the chair

You could make your own with a bolt and file.

They look like some kind of 'socket' bolt, tightened by an Allen key. Surely anything of the right size would do the job? Unless there's a special fixing inside the joint.
I could have a look through my 'miscellaneous' tins if you'd like.

Cheers

it looks like a bolt used in cars to fasten seats and seat belts what about a car breakers ?
 
Try one of the long established garden furniture companies - somebody like Westminster :https://westminsterteak.co.uk/index.php/refurbishment-service and ask them if they can supply them. If you look at the photo of the chair these are the type of bolts you are after - you may also need the corresponding cap that acts as a nut for some of them. Not sure about you type but mine have the thread all the way to the end.

I think they're called "custom"

:wink:

No they are from some mass produced eastern chairs, I know it looks a bit home made but its just the wear/ weathering.

I could just use any old bolt but because they are sliding in a groove the thread would start to chew up the wood, hence the unthreaded bit at the end. Doesn't seem to be available in this country despite a lot of searching...
 
Couldn't find anything I'm afraid and I expect you've found The flat top hex bolts on fleabay, some are stainless.
Without the use of a metal lathe, With some careful use of the drill chuck and angle grinder looks to be the only way to make up some sets.

Could be a low profile socket screw with just a reduced end. Should be easy enough to turn the end down if you can get the screws.

I guess it depends what you mean by "custom". Mass produced Bailey planes have quite
a few nuts and bolts that I would deem "custom"; they may be made in substantial
numbers, but they're not used on anything else (e.g. the notorious #12 x 20 TPI bolts, the l/h thread adjuster screw)

I think your bolts are no more (and no less) custom than that.

You may be right, shame as I like the design and the chairs are comfortable. I will have a chat with the guys in the local light engineering workshop I expect they will be able to help. I don't have a metal working lathe unfortunately.
 
How many do you need? If it's only 2 or 4 then a few minutes with a file is all you need. Or you could get smooth ends by filling up some of the thread with epoxy, rather than removing metal. Or add some suitably sized tube. I'm sure there must be a practical answer!
 
Hmmm, all possible answers, I will be making 4 chairs so 8 bolts needed. Since the chairs will be oak I will need to use stainless steel bolts, and have tried filing ss before with not much success. I like the idea of gluing a piece of tube, it's just finding the right sizes, I run the risk of spending more time and effort on these 8 bolts than on the chairs themselves. Thinking about finding another design tbh
 
You can lock two nuts together on a bolt leaving the required amount of thread showing, and with a new file wizz round filing off the threads.
Should tale an hour at the most even with SS bolts.

Pete
 
That doesn't work very well, the couple of teeth that in contact with the work clog very quickly, you still need to push the file across the work.
It will help smooth the filled bolt.

Pete
 
I would have thought that someone of this parish with a metalworking lathe would offer to help..... On the other hand, it's a good excuse to buy one. Not sure if my other half would accept that I want to help others so much though......
