Does anyone know what this type of screw is called in the UK?
I ask because I have some flat pack furniture that has been sitting in the attic for ages, and now I try to assemble it I find some of the screws are missing. Unless I can buy some more screws like the one pictured I'm going to have fun trying to assemble the furniture.
The screw has a 4mm hex socket in the end. I'd guess they're targetted at us amateur flat pack assemblers rather than the professional woodworkers. But as I don't know what this type of screw is called I don't even know where to start Googling.
Later:
Many thanks to everyone who answered. Several people suggested this is a custom made screw and I suspect they are correct. The paperwork with the furniture (a bed) is missing, but I think it is this bed made by Birlea.
With clues from all the answers I've found several similar screws - they all have sharp points but I don't think that matters as I suspect the tips have been removed just to stop amateurs like me impaling themselves. The closest seems to be these screws from Spax, though they are startlingly expensive! Searching for timber construction screws, lag screws and coach screws returns an array of likely looking hits.
