Symptoms

  • Screwdriver slips without turning the screw
  • Screw head looks rounded or chewed up
  • Screw won't back out even when it turns
  • Corrosion visible around the screw

Likely causes

  • CommonCorrosion seizing the screw threadsMoisture around the handle base can corrode the screw over years.
  • CommonStripped screw head from a poor-fitting screwdriverUsing the wrong size or type of driver rounds off the head.
  • PossibleOvertightened screw from a previous repairCan make it harder to break loose.
  • Less commonPaint or debris filling the screw headCan prevent a driver from seating properly.

What to do

  1. Clean out the screw head with a small pick or toothbrush to remove any debris or paint.
  2. Apply penetrating lubricant to the screw and let it sit for 10–15 minutes.
  3. Try a properly sized screwdriver again, pressing firmly while turning to get better grip.
  4. If the head is stripped, try a rubber band between the screwdriver tip and the screw for extra grip, or use a screw extractor tool.
  5. As a last resort, a small manual screw extractor or a Dremel to cut a new slot can work.
  6. Once removed, replace the screw with a new one if it's damaged, coating threads lightly with anti-seize to prevent future sticking.
  7. If the screw truly won't come out, some faucet manufacturers sell replacement handle assemblies that avoid needing that screw removed.
