Hex screwdriver sizes are as follows:
- 5/64“ for motor screws and locking collar set screws (grub screws)
- 3/32” for structural screws
- 5/32“ for playfield screws
The 3/32” and 5/64“ non-ball end hex screwdrivers that are available in the Performance Tool Kit can be “renewed” when they round off by grinding the rounded end off on a bench grinder or belt sander. You can also remove the metal shaft from the holder using a pair of pliers and flip the shaft around in the handle. This does not work with the 3/32” ball end screwdriver, as the shafts on those are larger than 3/32“.
The Wiha screwdrivers are expensive, but very high quality and round less frequently than the performance tool kit screwdrivers do.
Torx screwdriver sizes are as follows:
- T15 - Star drive structural screws
- T8 - Star drive couplers
Wrench sizes are as follows:
- 11/32” - normal hex nuts
- 1/4“ - standoffs
- 7/16” - large playfield screws
11/32“ nutdrivers and combo wrenches are commercially available. The stamped steel combo wrenches are not available separately from VEX and must be purchased as part of the Tool Kit
