Unknown screw type- pls help ID!

[Tom lanzafame]

Hi there,

I came across a type of screw that I’m not familiar with. It’s to attach an arm test to an old chair.
The screw it’s self is attached to the arm but there is another part which goes underneath (that which I’m holding in photo) which has the corresponding thread inside the hollow barrel.
Any idea how to find a replacement and what it’s called so I can search for it?
Thanks!
Tom

Binder screw. What size is the thread? Can the head of the replacement binder screw be bigger than the old one? Have you lost one presumably?

Steel ones are stronger

The male part is a screw, the female part is a nut.

Hence sometimes called a sex bolt

Thanks everyone.
I never knew this forum would lead me to sex.
