Place a rubber band over the stripped screw head and press your screwdriver into it firmly while turning counterclockwise. If that fails, use a screw extractor, vise-grip pliers, or drill out the screw. Always wear safety glasses and work slowly to avoid damaging the workpiece.
Why Stripped Screw Heads Happen
Stripped screw heads occur when the recess (Phillips, flathead, Torx, etc.) becomes rounded or damaged, so the screwdriver can no longer grip. Common causes include using the wrong size or type of driver, applying too much torque, or the screw being rusted or painted over. Soft metals like aluminum or brass strip more easily than steel. Understanding the cause helps prevent future stripping. For example, using a Phillips #2 bit in a #1 recess will cam out and strip the head. Always match the driver size and type to the screw.
How to Fix a Stripped Screw: 5 Proven Methods
Our editorial team compared specifications, buyer feedback and key decision factors to compile these methods. Always start with the least invasive technique and escalate if needed. Wear safety glasses and work in a well-lit area.
- Rubber Band Method - Place a wide rubber band over the screw head. Press your screwdriver firmly into the band and turn counterclockwise. The rubber fills the damaged recess and provides traction. Best for lightly stripped screws. If the band tears, try a thicker one or move to method 2. For example, a thick rubber band from a produce bunch works better than a thin one.
- Screw Extractor - Select a screw extractor set (e.g., Irwin or Craftsman). Drill a small pilot hole into the center of the screw head using a drill bit slightly smaller than the extractor. Insert the extractor, tap it gently with a hammer, then turn it counterclockwise with a tap handle or drill in reverse. The extractor bites into the screw and backs it out. Ensure the extractor is straight to avoid breaking it.
- Vise-Grip Pliers - If the screw head protrudes above the surface, clamp locking pliers (vise grips) onto the head as tightly as possible. Turn the pliers counterclockwise. For countersunk screws, you may need to first notch the head with a hacksaw or Dremel to give the pliers a grip. For example, cut a slot across the head to create a flathead recess.
- Drill Out the Screw - Use a left-hand drill bit (available in most hardware stores) in reverse rotation. Drill into the center of the screw head. The bit may catch and spin the screw out. If not, continue drilling until the head separates, then remove the remaining shank with pliers. Protect the surrounding surface with painter's tape. For example, use a 1/8 inch left-hand bit for a #8 screw.
- Cut a New Slot - For screws with a slightly damaged head, use a rotary tool (Dremel) with a cutoff wheel to cut a deep slot across the head, creating a flathead recess. Then use a flathead screwdriver to turn it out. This works well on pan-head or round-head screws. For example, cut a slot about 1/8 inch deep to ensure good engagement.
Safety Tips for Stripped Screw Removal
Safety should be your top priority. Always wear safety glasses to protect against metal shavings and broken tools. Use sharp drill bits and apply steady, even pressure to avoid slipping. If using a screw extractor, ensure it is straight and centered to prevent breakage. Broken extractors are difficult to remove. Work in a stable position and keep hands clear of the drill chuck. For electrical or gas-related screws, turn off power or shut off the gas supply before attempting removal. Also, consider using a magnetic pickup tool to retrieve metal shavings.
When to Replace the Screw
After removal, inspect the screw. If the threads are damaged, rusted, or the head is completely gone, replace it with a new screw of the same size and material. For critical applications (e.g., automotive, structural), use a grade-8 or stainless steel screw. If the original hole is stripped, consider using a larger screw or a thread repair insert (Heli-Coil). Always apply a drop of threadlocker or anti-seize compound to prevent future seizing. For example, use blue threadlocker for removable applications and red for permanent ones.
When to Call a Professional
Call a professional if the stripped screw is in a sensitive or expensive component like a laptop, camera, or musical instrument. Also seek help if the screw is in a load-bearing structure, electrical panel, or gas line. If you have tried multiple methods without success, a pro can use specialized tools like an impact driver or ultrasonic removal. Know your limits to avoid costly damage. For example, a stripped screw in a smartphone motherboard is best left to a repair technician.
Preventing Stripped Screws in the Future
To avoid stripped screws, always use the correct screwdriver bit that fits snugly into the recess. Apply steady, even pressure and turn slowly. Avoid using power tools at high torque settings for delicate screws. Lubricate screws with a drop of oil or penetrating fluid before removal, especially if they are rusted. For frequently removed screws, consider using socket cap screws or hex head bolts that are less prone to stripping. Also, replace worn bits regularly to ensure a good grip.
