The Ultimate Guide to Screw Extractors: Efficiently Remove Damaged Screws

Phillips-head screw extractors are a handy tool to have around for removing damaged or stripped screws. They work by using a tapered drill bit with reverse threading to bite down and lock into the head of the screw, allowing you to twist it out. There are various types of screw extractors available, including pliers, drill attachments, and screwdriver-like tools. Screw extractors can be used on screws embedded in metal, wood, or plastic, although extra care is needed to avoid damaging the surrounding material.

Understanding Screw Extractors

Screw extractors are essential tools for both professionals and DIY enthusiasts. They are designed to remove screws that are damaged, stripped, or broken, making them invaluable in various situations. The effectiveness of a screw extractor depends on its design, material, and the type of screw it is intended to remove.

Technical Features of Screw Extractors

When selecting a screw extractor, it’s crucial to consider its technical features. Below is a comparison table highlighting the key characteristics of different screw extractors:

Types of Screw Extractors

Screw extractors come in various types, each designed for specific applications. Here’s a comparison table of the different types of screw extractors:

Type	Description
Manual Extractors	Handheld tools that require manual effort to remove screws.
Drill Attachments	Attach to a power drill for faster extraction.
Pliers	Specialized pliers designed to grip and twist out screws.
Screwdriver-like Tools	Resemble traditional screwdrivers but are designed for damaged screws.
Left-Handed Drill Bits	Drill bits that turn counterclockwise to help loosen screws.

Choosing the Right Screw Extractor

When choosing a screw extractor, consider the type of surface you will be working on, as well as the size and type of screw or bolt you need to remove. Here are some tips for selecting the right screw extractor for different surfaces:

Wood

For wood surfaces, look for a screw extractor specifically designed for wood screws. These extractors usually have a spiral flute design, which makes it easier to remove the screw by gripping it tightly. The NEIKO 01925A Screw Extractor, made from premium HSS M2 steel, is a great option for wood surfaces.

Metal

When working with metal surfaces, choose a screw extractor made from hard metals, such as high-speed steel (HSS) or cobalt steel. The IRWIN Screw Extractor Drill Bit Set, made from cobalt, is a good choice for metal surfaces as it includes multiple pieces that can remove broken screws and studs.

Plastic

For plastic surfaces, a screw extractor with a reverse spiral design is ideal. The Irwin Bolt-Grip 5-Piece Bolt Extractor Set has a reverse spiral design that bites into the bolt head, making it easier to remove bolts that have been painted over or have rounded-off heads.

Electronics

When working with electronics, such as laptop computers, use a small screw extractor kit as the screws in these devices are usually very tiny. The Alden Grabit Micro Broken Bolt Extractor 4-Piece Kit is a great option for electronics.

Thin Surfaces or Softer Materials

For thin surfaces or softer materials, a straight flute extractor is a good choice. Straight flute extractors can remove screws and bolts by themselves or with the help of a nut. The Alden Grabit Pro Bolt and Screw Extractor 4-Piece Kit is a reversible design that eliminates the guesswork of matching drill bits with extractor sizes.

How to Use a Screw Extractor

Using a screw extractor is straightforward, but it requires careful attention to detail. Here’s a step-by-step guide on how to effectively use a screw extractor:

Prepare the Screw: Align a center punch with the center of the stripped or broken screw. Lightly strike the punch with a hammer to create a small indentation in the center of the screw.
Drill a Guide Hole: Select a drill bit that is slightly narrower than the screw head and attach it to your drill. Apply a small amount of thread cutting oil to the head of the broken screw to make drilling easier. Drill about 1/8 to 1/4 inch into the screw head.
Insert the Screw Extractor: Insert the pointed threaded end of the screw extractor into the hole you drilled. If your extractor has a tap handle, attach it and turn the extractor counterclockwise by hand.
Remove the Screw: Continue turning the extractor counterclockwise until the screw is completely removed. If the extractor doesn’t bite into the screw, try drilling a little deeper or using the next size up extractor.

Conclusion

Screw extractors are invaluable tools for anyone dealing with damaged or stripped screws. By understanding the different types and features of screw extractors, you can choose the right tool for your specific needs. Whether you are a professional tradesperson or a DIY enthusiast, having a reliable screw extractor on hand can save you time and frustration.
