A broken faucet screw can keep you from getting water from your kitchen or bathroom sink. Faucet screws are used to hold the faucet handles in place. The handles turn a faucet stem, which allows the water to flow through the faucet spout. A broken faucet screw can be removed or extracted in a number of ways. Try one of the steps or a combination to remove the screw and get your faucet working again.
Remove the faucet screw cap, if present. These usually are concealed as the "Hot" or "Cold" temperature indicators on the top of the faucet handles. Insert the edge of a flat bladed screwdriver or sharp knife underneath the faucet screw cap and pry it off to remove it.
Spray the broken faucet screw with penetrating lubricant. Unscrew it with a pair of pliers.
Insert a metal cutting blade into a rotary tool. Saw off the head of the screw. Pull off the handle straight up. Use a pair of pliers to remove the base of the screw by twisting counterclockwise.
Attach a screw extractor to a power drill. These extractors have reverse threading that backs the broken screw out slowly. Set your drill on the lowest speed and slowly back it out of the faucet.
Use an impact driver to loosen the screw. Fit the head of the impact driver over the screw. Tap on the head of the driver. Continue this process until the screw is extracted.
Use the proper safety equipment, including glasses and gloves, when removing a broken screw.
