Something like that it's too bolt a chain to my jetski trailer to secure the ski to when not in use to deter the little scrotes the ones I have seen have been a cone shape with 3 slots in them that I'd think a special spanner goes on to put them on

I'm thinking something like m8/10 around 40-50 mm long but I'll have to double check and if you have something like that it would be great

And these as its a noisy job to remove

All the others the thief can buy a tool to easily remove them

Just use a normal bolt and put a blob of weld on the nut?
They'll only cut the chain instead.

hope u got a good chain ?

Take regular threaded stud, put a cross cut in the end with a hacksaw. Fasten up and then peen the end to spread it and the nut cannot be removed without a grinder etc.
My std with security shuuers and such. If they bring cutting gear anything is done for

I'll see what happens I'd like something that fits without sharp edges

There are no sharp edges - you peen it! You only need a couple of mm to lack the nut and as you peen you are deburring.

I thought you meant cut and fold both sides like a split pin I'll give it a go

To be clear cut a cross in the end and take a ball hammer and spread the last section of thread out so it cannot be unthreaded. I mean you don't need to do much but if you realy wanted to you could given time form a type of rivet head, pointless but possible

Bit of stud with a shear nut on either end the type thats used on park fencing where the hex breaks off and just leave a cone

 

[Thrashsmith]

Do both? Shear nut + pein. That's what I did on some gates I recently finished, though I didn't first cut the thread as Kent does.

In fairness I never secure my gates from theft.. It's incredibly rare here to have gates stolen. Scrap is low and second hand gates no matter how nice are hard as heck to sell for decent money and very identifiable
The only time I secure in the way mentioned is on the likes of security measures like the fitting of security grills etc.
