Skeletal mesh : attach specific bone to a socket

Hi,
I’ve got a skeletal mesh (in a blueprint) and I’m looking for a way to attach a specifi bone to another mesh (static for this purpose). I’ve got a socket on the StaticMesh, and my skeletalmesh’s skeleton is made of 3 bones in line. I want to attach a bone that is NOT the root bone to the StaticMesh. Is that possible ? Or do I have to change my root bone for this bone ?
For details the skeletalmesh is a swipe card and it’s holder (a pincer). The root bone is on the card itself, and I want to attach the pincer to a staticmesh.

Still no answer to this? :frowning:

I’m looking for a way to this too (and this was the first hit google search brought up:) for a weapon with a left-hand and a right-hand part. Using 2 separate meshes seems redundant while I don’t want to include the character skeleton to be able to animate all 3 together.
It would fine if I could just take the bones of each gun and attach them to the respective sockets, like SocketHandR and SocketHandL or even SocketHolsterR/L,
