Will this work on a SCREW EYE and not a Hook ??? Screw eye is 5/16" and 2 7/8 long !!! I will take three if they will work on 5/16' screw eye. Why is no size shown ??? Thanks, FESTOOL Team !!!

No, it will not work with that type of fastener. The hook driver is only open on one side and therefore cannot interface it.
