While assembling a treadmill, I screwed through one of its wires (pretty sure it's the I/O cable). Can I fix this with electrical tape, or do I need to get this repaired? Any advice is much appreciated!

If you're absolutely sure you only damaged the outer insulation of an I/O cable then electrical tape would be Ok. If any other cable insulation or conductors are at all damaged, then you should get it repaired or get a replacement cable. Treadmills can be dangerous so you don't want to take chances with them malfunctioning or the dead man switch not working.

Thanks Jack. The screw went through the insulation and likely the conductors - I could see through to the other side. Since it's probably involved in treadmill controls, I'll get it repaired.– SteveJJul 14, 2021 at 4:10

1if you can see any metal in the hole, don't use tape, otherwise it's probably ok.– JasenJul 14, 2021 at 8:37
That appears to be a data cable.
data is normally low voltage and electrical tape would be fine starting 1/2” or more away make a tight wrap over coating at least 1/2 with each additional wrap will provide plenty of insulation for this.
The NEC doesn’t deal with equipment but having worked for a large company that was the method used to repair skinned cables.
If copper is showing on multiple conductors sealing then protecting with tape is preformed for field repairs.

+1... definitely strip (carefully!) the outer sheath to see what has happened to the interior wires. Jul 14, 2021 at 3:16
