Rusty screws can quickly become a hindrance, so it’s best to remove them before the damage worsens.

This oxidation of the metal can bond the screws too tightly, preventing standard tools from being able to remove them.

However, with the right tools and approach, you can tackle even the toughest of screws. Stick with us as we guide you through the removal process for rusty screws, ensuring a quick and clean task.

Gather The Necessary Tools

Before you begin, ensure you have the following tools and products:

Hammer
Pliers
Screwdriver
Lubricant (WD-40 or a rust penetrant)
Drill with screwdriver bits
Blowtorch or heat gun
Safety goggles

1. Prepare the Area

Before you begin, clear the area of any obstructions and ensure proper lighting to prevent any accidents or injuries.

Put on your safety goggles to prevent rust from getting in your eyes, and open all windows to ensure adequate ventilation indoors.

2. Break the Rust Seal

Gently tap the hammer to the screw to crack the seal of rust around the screw. This will loosen the screw, making it easier to twist.

Apply a layer of lubricant, such as penetrating oil WD-40 or Liquid Wrench. Spray this around the screw head and the threads (if reachable) and let it sit for at least 10-15 minutes.

After the time is up, tap the screw head gently with a hammer to further break down the rust.

3. Attempt to Unscrew

Before you begin, select the right screwdriver for your screw:

Philips head: for good grip.
Torx or hex: for specialised screws in electronics or machinery.
Flat-head: for single groove screws.

Then, position the tip of the screwdriver firmly to the head of the screw and turn it clockwise. Apply even pressure to unscrew the screw efficiently.

4. Use Pliers or a Drill

If the screw starts to turn but not all the way, use pliers to finish the job and remove the screw completely.

Using the pliers, hold the screw head and rotate it anticlockwise. This provides extra leverage, which is especially useful when the screw head is stripped or broken.

For screws that still refuse to budge, use a drill. Set this to a low speed to avoid stripping the screw head and start with gentle pressure, gradually increasing for a successful job.

5. Apply Heat (Optional)

If you still can’t get the screw to move, apply heat using a blow torch or heat gun. This will cause the metal to expand, breaking the rust’s grip.

Apply cold water immediately afterwards to create a thermal shock. This will loosen the rust even more. Then, unscrew the screw. An impact driver may be useful for deeply rusted screws.

6. Clean Up

Once the screw has been removed, clean up any debris or materials from the area and apply a rust inhibitor.

This will create a protective barrier to prevent moisture and air from sitting on the metal surface.

FAQs

How can I prevent screws from rusting in the future?

Use rust-resistant screws, such as those composed of stainless steel or coated in rust-resistant coatings.

Another helpful method is to apply a protective layer, like a rust inhibitor or oil, and store screws in a moisture-free environment.

What should I do if the screw head is stripped?

If the screw head is stripped, try the following:

Use a screw extractor kit
Use pliers to grip and turn the screw
Cut a new slot into the screw head with a rotary tool
Drill out the screw

Can household items be used as lubricants for removing rusted screws?

Yes! Common household items such as cola, lemon juice, or vinegar can be used to help lubricate the screw.

Although they might not be as powerful as specialised rust penetrants, these contain acids that help to breakdown rust.
