What to use instead of a screwdriver

If you need a temporary substitute, the best option is a properly sized multitool with screwdriver bits; if that is unavailable, a few common household items can work for simple screws like flatheads. For a quick fix, people often use a coin, butter knife, or metal nail file, but only on the right screw type and only with care to avoid damage.

Quick Scoop

For flathead screws, the most common makeshift choices are:

  • A coin for small, slightly loose screws.
  • A butter knife for light-duty turning.
  • A metal nail file for tiny screws or tight spaces.
  • A flat-edged tool like a small chisel or similar sturdy edge, if it fits the slot well.

What is safest

The safest answer is still to use the correct screwdriver or bit, because makeshift tools can strip the screw head or slip and injure you. If you only need to get through one quick repair, choose the tool that fits the screw head most closely and apply slow, steady pressure.

Avoid these mistakes

  • Do not force a tool that is too wide or too thin, because it can damage the screw head.
  • Do not use fragile items that can break under pressure.
  • For delicate electronics or valuable items, avoid improvised tools unless you are sure they fit safely.

Best practical pick

If you want one answer: use a multitool with interchangeable bits if you have it, and otherwise a butter knife or coin only as a temporary backup for a flathead screw.
