Using a metal tool will change the inductance, meaning have to turn a bit, remove tool for effect, replace tool and adjust again and again.
A tool may be able to be fabricated from a rigid thermoplastic sleeve, heated to the point of softening. Then insert a warmed Allen key the same size as the hex in the coil. Allowed to cool...

Brenda, you might try a nylon socket head screw as a tool. A 5/16 screw has a wrench size of 1/4 inch, a 3/8 screw is 5/16 which is also very close to 7mm or a M10 screw has a drive size of 8mm.
