What to Consider When Choosing the Best Screw Extractor

Screw extractors come in different types to suit different damaged fasteners. Read on to learn more about each type and crucial factors, including gripping power and the material one should consider when choosing the best screw extractor.


  • Bolt extractor: A bolt extractor looks similar to a standard socket head except for the spiral threads inside it. These threads bite into the bolt head as the user turns the socket counterclockwise using a socket wrench. The threads typically have a spiral pattern that becomes tighter with force.
  • Spiral screw extractor: A spiral screw extractor removes screws or bolts by fitting them into a hole that’s been drilled into the fastener’s head with a drill bit. The extractor has reverse threads that grip the screw as it rotates inside the hole counterclockwise. Many spiral screw extractor kits come with matching drill bits. Some are double-sided, with a drill bit on one side and an extractor on the other.
  • Extraction pliers: Extraction pliers are a good option for damaged screws or bolts whose heads are protruding from the surface of the material. This set of specialty pliers has teeth designed to grip firmly onto the head, allowing the user to remove the screw by attaching the pliers and turning them counterclockwise.
  • Stud and bolt extractor tool: This tool looks similar to the chuck of a power drill. Like extraction pliers, it only works with screws or bolts that are sticking out of the material. To use an extractor tool, place it over the head of the stud or bolt, then tighten the grip around it like a vice. Attach the end to a 0.375-inch or 0.500-inch ratchet and turn counterclockwise to remove the bolt or screw.

Supported Screw Size

Screw heads come in a wide variety of sizes, so it’s important to pay attention to what sizes the screw extractor can accommodate. Most sets include sizes ranging from 0.125 inches up to 0.625 inches. Larger sets have extractors as large as 0.875 inches and are capable of removing large bolts on vehicles and industrial machines. Other sets can remove tiny machine screws found in electronics, such as laptop computers with extractors as small as 0.0781 inches. While a small kit with four or five extractor sizes is adequate for most, it makes sense for pros or DIYers to invest in a set that can cover a broad range of sizes.

Gripping Power

Different types of screw extractors use different strategies for gripping a stripped or rusted screw or bolt head. Some drill into the head and use reverse threads to bite into and grip the head while others grab the head by fitting over it. While the latter generally creates more gripping power, this style of the extractor is limited to instances where the bolt or screw head is jutting out of the material enough to allow the tool to grip it.

The material type also affects gripping power. Drill bits and extractors made of high-quality steel alloys do a better job of boring into and gripping fasteners and last longer than those that use cheaper materials.


Since screw extractors must burrow into metal screws in order to work, they need to consist of hard metal. Most screw extractors are made of high-speed steel, the same steel alloy used in many drill bits and saw blades. This type of steel is harder than other alloys and is capable of enduring high temperatures without softening, a key characteristic for drilling into the heads of metal fasteners.

If it’s in the budget, cobalt steel is even better, but it’s also pricier. It’s harder than high-speed steel and holds up better to the high temperatures created by metal cutting into metal. Cobalt steel also has a higher tensile strength, which makes it a better choice for extractors with a narrower flute of 0.125 inches or less. Stay away from extractors that consist of softer alloys, as they will not be hard enough to do the job.

Ease of Use and Versatility

Screw extractors have features that make them easier to use and ensure that the right drill bit is used with the right extractor. Those that work in conjunction with a drill bit must match the bit size to be effective. This type of extractor should have the compatible drill bit size etched onto its side to avoid confusion.

Double-sided extractors are some of the most convenient models as they feature the drill bit and extractor on a single reversible shank, eliminating the need to hunt for a compatible drill bit. Simply drill the hole with one side, then flip the shank to apply the extractor.

Some kits use magnetic extension bit holders that can hold either the drill or extractor bit. This allows the user to quickly swap between them, speeding the screw removal process along.

Since screw and bolt extractor kits can include 30 pieces or more, most come with handy carrying cases that keep all of the pieces organized so they can be found when needed.

Tips for Using a Screw Extractor

Most screw extractor tools are easy to use, even for beginners. Here are a few valuable tips for using a screw extractor.

  • To use a screw extractor, begin by drilling a hole into the head of the damaged screw. Apply thread cutting oil to the drill bit prior to drilling. This will make it easier to drill through the metal by reducing friction.
  • Before attempting to remove the damaged screw with the extractor, apply penetrating oil to the screw’s threads. Wait at least 15 minutes after application to allow the oil to make its way into the threads, then use the extractor. The oil should help to loosen the screw, making it easier to remove.
  • If using a power drill to remove the screw, use a slow speed. This will maximize the drill’s torque and allow the extractor’s threads to grip the drilled-out hole in the head of the fastener. Using too high a speed can cause the extractor to slip in the hole.

FAQs About Screw Extractors

If you have additional questions about how to use a screw extractor, read on for answers to some common queries about these handy tools.

Q. What’s the use of the drill bit on the extractor?

The drill bit is a crucial part of the extractor that is used to bore a hole in the head of the damaged bolt or screw, creating a place for the extractor to penetrate and grip the screw head so you can remove it.

Q. What’s a screw extractor’s ideal length?

There really is no standard length for a screw extractor. In fact, short and long extractors work equally well at removing damaged screws and bolts. It’s more important to choose the correct diameter drill bit and extractor to suit the damaged fastener.

Q. How do I know which size extractor to use?

To determine the proper extractor size, begin by choosing the proper drill-bit size. The drill bit should be about half the diameter of the screw head. For example, to remove a 0.375-inch screw, begin by drilling a hole in the head with a 3/16-inch drill bit. Once the hole is drilled, use an extractor that’s slightly smaller than the drill bit—most kits conveniently match the bits on the kit to the extractor. The slightly smaller extractor should fit inside the hole but still be tight enough that its threads can lock into the hole’s contours.
