FR Allen Key 4mm

The standard Seba Allen key 4 mm is the Allen key which is delivered together with most FR and Seba inline skates. This Allen key has the right size for the wheel screws of alle Seba and FR inline skates and for most inline skates wheel screws (axes) of the other brands. It fits also on the frame screws of some inline skates. It is a simple Allen key that in 90% of the cases will do the job. But of course, if the screw is fixed too hard, you will need a somewhat better tool like e.g. this Sonic tool or this Allen Master key ).
