Need help identifying L shaped shelving supports

usignuolo

We recently found three shelves in our cellar which we decided to reuse. They come supplied with a set of shaped screwed end hook (like a small allan key with a screw on the long end of L). Basically the long of the L screws into the wall, leaving the short end pointing upwards. Each shelf has two holes, one at end underneath and they sit on the short end of the L screws, which point upwards.

Anyway two of the screws are missing and need replacing but I am struggling to find these on line. Anyone know what they are called, are they screws, hooks or something else?
