Screwdriver Slipping? How to Fix Stripped Screw Heads

Why Screw Heads Get Stripped

Stripping happens when the screwdriver bit loses its grip inside the screw head. The edges of the head become rounded or the internal cross or slot deforms. Common causes include using the wrong tip size, applying too little downward pressure, or using a worn bit. Power tools at high torque can also strip screws quickly if the bit cams out. Understanding why it happens helps you choose the right fix.

How to Fix a Stripped Screw Head

Try these methods in order from least invasive to most aggressive.

1. Rubber band method. Place a wide rubber band (or a piece of a latex glove) over the screw head. Press your screwdriver bit firmly into the rubber and turn slowly. The rubber fills the gaps and increases friction. Works best on moderately stripped Phillips or flathead screws.
2. Screw extractor. If the rubber band fails, use a screw extractor set. Drill a small pilot hole into the center of the stripped screw head (use a drill bit slightly smaller than the extractor). Insert the extractor, tap it gently, then turn counterclockwise with a tap wrench or drill in reverse. The extractor bites into the screw and backs it out.
3. Impact driver. For stubborn screws, a manual impact driver (struck with a hammer) can deliver a strong rotational force while pushing the bit into the head. Set the driver to reverse, place the bit firmly, and strike with a hammer. The combined force often breaks the screw loose without further stripping.

If none of these work, you may need to drill out the screw entirely or use a rotary tool to cut a new slot.

When to Replace the Screw

Once you remove a stripped screw, always replace it with a new one of the same size and type. The stripped head means the threads are likely damaged too. Using a new screw ensures proper grip and prevents future issues. If the original hole is enlarged, use a slightly larger screw or fill the hole with a toothpick and wood glue before inserting the new screw.

How to Prevent Stripping

Prevention is better than any fix. Follow these tips every time you drive a screw.

• Match the tip size exactly. For Phillips, use the correct size (PH0, PH1, PH2, etc.). For flathead, the tip should fill the slot width. For Torx, hex, or square, use the exact size.
• Apply firm downward pressure. Push the screwdriver straight into the screw head before turning. Keep the tool aligned with the screw axis.
• Use a sharp, unworn bit. Replace bits that show rounding or wear. A worn bit increases cam-out risk.
• Pre-drill pilot holes. For hardwoods or dense materials, drill a pilot hole slightly smaller than the screw diameter. This reduces the torque needed.
• Use the right tool for the job. A manual screwdriver gives more control than a power drill. If using a drill, set the clutch to a low torque setting and drive slowly.

FAQ

Does the rubber band trick actually work?

Yes, the rubber band trick often works on moderately stripped screws. The rubber fills the gaps between the screwdriver bit and the stripped head, providing extra grip. It works best with a flat rubber band or a piece of a latex glove. Apply firm downward pressure and turn slowly. If the screw is severely rounded, you may need a screw extractor.

Can I use an impact driver on any stripped screw?

An impact driver is most effective on screws that are not completely rounded out. The hammering action helps drive the bit into the remaining material while turning. Use a high-quality bit that fits as snugly as possible. For very small or delicate screws, an impact driver may cause damage, so consider a manual screw extractor instead.

How do I choose the right screwdriver tip to prevent stripping?

Match the tip size exactly to the screw head. For Phillips screws, the tip should fill the cross without wobbling. For flathead, the tip width should match the slot width. For Torx or hex, use the correct size. Apply steady, firm pressure directly downward (axial force) before turning. Avoid using worn or rounded bits, and never use a power tool at high speed on a tight screw.
