What type of screw/bolt is this?

[5 albert square]

Hello,

Can anyone help me identify what type of screw/bolt this is please? Having to buy a replacement.

You could replace with a standard screw thru a washer.
It’s an Allen head screw , can be purchased but not essential .

Thanks. It's for a chair. 1 screw fell out today and it won't stay together without it. Would these do as a replacement?

The original screw is a pan head allen......but we don’t know if it has a machined thread or a standard screwed one.
Remove one and give us a look!

It looks like it could be a rivet to me, a badly formed pop-rivet?

Second pic shows it as an allen/hex head fitting.
@5 albert square, you need to show us what the thread is like. If it's a 'machine screw' it will be the same diameter all the way to the tip. If the tip has a point like a normal wood screw it will be a self tapper. Either way, you will need to know what the diameter and length is so you can buy the right size.

Spec savers ?

It might be a button-head screw, commonly used to fix fairings and other plastic parts onto motorcycles, usually Allen key, in satin black or plated silvery, or stainless.



Also available are flanged button-headed

I can see the head clearly, and I can see what appears to be a hex shape, but a badly deformed hex - hence my assumption of a rivet.

It doesn't look anything like a rivet.

This is the other screw.

Clearer, but I am still not seeing an Allen key socket, despite the surrounding edge of it being perfectly clear. Yes, it is definitely a screw, and not a rivet

Maybe 6mm?

That’s because it’s upside down , pic does not show the head .

OK - OP, can you take another photo, close-up, facing the head of the screw/bolt please?
