Looking for whatever this is called - I've located the type of thing it is from Amazon as its basically what is used for connecting Pool / Snooker cues together - a Male and Female connector.

I am however looking for a larger version of the same - to allow connection of two parts of wood via a screwed/glued in Male.
As what I have it planned for is somewhat chunkier than a pool cue it an be larger and it could even come with Two male ends and one female connector?
The thing I'm trying to join is standard tool handle width.
Ideas/Links for what this is called from the Tinkerers please. Thank you.
