How to Easily Remove Rusted License Plate Screws with Pliers

Removing rusted license plate screws can be a frustrating task for any vehicle owner. When exposed to the elements, these small but critical fasteners often become stubborn obstacles due to corrosion. The good news is that with a pair of pliers and the right technique, you can extract these troublesome screws without damaging your car.

Simply grip the screw head firmly with locking pliers or vice grips, apply steady pressure while turning counterclockwise, and be patient with the process. A penetrating lubricant like WD-40 applied beforehand can help break down the rust and make removal significantly easier. 

Why Rusted License Plate Screws Are Hard to Remove

Rusted license plate screws become difficult to remove due to oxidation that fuses metal surfaces together. The rust creates a tight bond between the screw and surrounding metal material. Weather exposure accelerates this rusting process, especially in humid or coastal areas. Time only worsens the problem, making screws increasingly stubborn to turn.

Rust expands the metal, creating pressure that can jam screws in their holes. This expansion causes the screw to become wedged tightly against the surrounding metal. The corrosion deteriorates the screw head, making it harder to grip with tools. Attempting removal often leads to stripped screw heads if proper techniques aren’t used.

What You’ll Need to Remove Rusted License Plate Screws

A good set of locking pliers or vice grips is essential for gripping stubborn screw heads. Penetrating oil like WD-40 or specialized rust remover helps break down corrosion. A wire brush can be useful for cleaning rust from the screw head surface. Protective gloves will shield your hands from sharp metal and chemicals.

You may need a screwdriver with the appropriate head type as a backup option. A small hammer can help tap the pliers for better grip or loosen stuck components. Rust converter can be applied if you encounter extremely corroded screws. Having replacement screws ready ensures you can immediately secure the license plate afterward.

Step 1: Assessing the Condition of Your Rusted Screws

Examine the screws to determine how severely they’ve been affected by rust. Look closely at the screw heads to check if they’re still intact enough to grip. Try turning each screw gently with a screwdriver to test resistance levels. Note which screws might need special attention due to extreme corrosion.

Check the surrounding area for rust damage that might complicate removal. Determine if the screw heads are stripped or still have defined edges. Take photos of the current plate position if you need reference for reinstallation. Ensure you have adequate lighting to properly see what you’re working with.

Step 2: Choosing the Right Pliers for the Job

Select locking pliers or vice grips with adjustable jaw pressure for optimal grip. Needle-nose pliers work well for recessed or hard-to-reach license plate screws. Ensure the pliers you choose have serrated jaws for better gripping power. The size should match your screw heads—not too large or small.

Channel-lock pliers offer good leverage but require more space to operate. Test the grip strength of your pliers before applying them to the rusted screws. Pliers with rubber-coated handles provide better comfort during extended use. Keep alternative pliers nearby in case your first choice proves ineffective.

Step 3: Applying Penetrating Oil to Loosen the Rust

Spray penetrating oil directly onto the rusted screw and surrounding area. Allow the oil to sit for at least 15-20 minutes to penetrate the corrosion. For extremely rusted screws, consider applying oil and waiting overnight for best results. Tap the screw gently with a small hammer to help the oil penetrate deeper.

Apply a second application of penetrating oil if the first doesn’t seem effective. Use a cotton swab to apply oil to hard-to-reach areas around the screw. Wipe away excess oil to maintain a clean work environment. The oil will work by breaking down the rust bonds between the metal surfaces.

Step 4: Using Pliers to Grip and Turn the Rusted Screws

Position the pliers squarely on the screw head, ensuring maximum contact surface. Adjust the pliers to lock tightly on the screw without slipping off. Apply steady downward pressure while turning the screw counterclockwise to loosen. Maintain a firm grip and use smooth, controlled movements rather than jerky motions.

If the screw begins to turn, continue applying constant pressure until removal. Should the pliers slip, readjust your grip and try again with slightly more pressure. For severely rusted screws, try alternating between clockwise and counterclockwise motions. Take brief pauses between attempts if the screw refuses to budge initially.

Step 5: Dealing with Stubborn Screws and Alternative Methods

For extremely stubborn screws, try applying heat with a mini torch to expand the metal. Create a groove across the screw head using a rotary tool if pliers can’t grip. Consider using an impact driver with the appropriate bit as a powerful alternative. As a last resort, drill through the screw head using a metal drill bit.

Try using a screw extractor tool designed specifically for removing damaged screws. Apply more penetrating oil and let it sit longer if initial attempts fail. Gently tap the screwdriver with a hammer while turning to help break the rust seal. Remember that patience is crucial when dealing with particularly stubborn screws.

Safety Tips for Removing Rusted License Plate Screws

Always wear protective gloves to prevent cuts from sharp, rusty edges. Use safety glasses to shield your eyes from rust particles and debris. Work in a well-ventilated area when using penetrating oils or chemical rust removers. Keep your face away from the work area to avoid respiratory irritation.

Avoid applying excessive force that could damage your vehicle’s body panels. Have a first aid kit nearby in case of minor injuries from sharp edges. Be cautious with heat-based methods that could damage paint or surrounding materials. Take regular breaks to prevent hand fatigue that might lead to accidents.

Common Mistakes to Avoid When Using Pliers for Rusted Screws

Avoid using worn-out pliers with damaged jaw surfaces that might slip. Don’t rush the process by skipping the penetrating oil application step. Never force pliers with excessive pressure that could break the screw head off. Avoid twisting too hard in one attempt, which can strip what remains of the screw head.

Don’t use pliers that are too large or small for the specific screw head. Avoid sudden jerking movements that can cause the pliers to slip and damage surfaces. Never use pliers with loose pivot points that won’t maintain consistent pressure. Don’t give up after just one or two attempts without trying different angles.

How to Identify If the License Plate Screws Are Beyond Repair

Screws that crumble or flake apart when touched are beyond salvation. If the screw head is completely worn down with no edges to grip, replacement is necessary. Extensive rust that has consumed most of the screw indicates replacement is needed. 

Signs of metal fatigue like cracks in the screw indicate imminent failure. If rust has spread from the screw to surrounding metal, more significant repair may be needed. Screws that appear to be fused completely with the surrounding metal require drilling. Excessive wobbling in a screw that won’t turn suggests the threads are destroyed.

How to Prevent Rust from Affecting Your License Plate Screws

Use stainless steel or galvanized screws when replacing your license plate hardware. Apply a thin coat of anti-seize compound to new screws before installation. Consider using plastic screw covers that shield metal from moisture exposure. Regularly clean your license plate area, especially after winter driving conditions.

Apply a small amount of water-resistant grease to screws during maintenance checks. Use clear nail polish on screw heads as an inexpensive protective barrier. Check and tighten license plate screws periodically to prevent water infiltration. Consider applying automotive wax to the entire license plate area during routine car washing.

When to Use WD-40 vs. Penetrating Oil for Rusted Screws

WD-40 works well for light rust and general maintenance situations. Dedicated penetrating oils like PB Blaster are better for severely rusted screws. WD-40 acts faster but doesn’t penetrate as deeply as specialized products. Use WD-40 for preventative maintenance and quick jobs requiring less penetration.

Penetrating oils should be used when dealing with years of accumulated rust. WD-40 is more readily available and works for moderate rust problems. Specialized penetrating oils require longer soak times but provide better results. Consider using penetrating oil for critical fasteners that must be preserved during removal.
