There are several effective methods to get out a stripped screw. Some common ways include:

• Using a wide rubber band or rubber glove placed over the stripped screw head to increase grip, then turning the screwdriver slowly counterclockwise.
• Applying friction drops (available at hardware stores) to add resistance before turning the screw.
• Using pliers (channel lock or locking pliers) to grip the screw head or shaft and twist it out.
• Cutting a new slot into the screw with a rotary tool and using a flathead screwdriver to turn it.
• Adding superglue or epoxy to bond the screwdriver to the screw head, then removing it after drying.
• Using screw extractor bits designed to grip and remove stripped screws.
• Tapping a manual screwdriver into the screw head with a hammer to lodge it in for better grip.

These techniques vary depending on the screw type, how stripped it is, and the tools available.

Would a specific method more suited to a particular screw type or toolset be helpful?
