French door hinge adjust

[Stormfly1985]

I'm struggling to find a key to fit the hinge adjust slot on my wood framed French doors.

It's a small square hole rather than a traditional Allen key. Looks about 4mm.

Any thoughts on what the right tool is?

Cheers

Anyone?

Plenty of 4mm square bits out there - google is your friend. Or if you aren't sure of the exact size, look for a manufacturer's name on the hinge and call them. Or just buy a set of bits from 3 - 6 mm, whatever is easiest!

Thanks - I did a google and couldn't find anything appropriate. I'll take another look.
