Hi Guys,
Does anyone know what this head type is called and/or when I can get a bit for it?
Its on our security sliding fly wire door. It looks like its stopping me from replacing the door rollers that 'she' wants fixing.....

It must be a 'security' type as it has a nub in the centre. A Clover Bit?....lol
