The screw you can make from a 8/32 flat head screw just check the length.You'll have to grind part of the head to fit the inside plastic peace so it does not turn when you loosen and tighten the screw. The tool is a flat screwdriver with a slot in the center look at Tim's pic above you can make one in 5 min.Make the screw driver take it apart make the new screw and use the old inside nut with you're screw driver ,use a new 8/32 nut to hold the dis. wire and you're done
