If you use a large 13 or 25-piece kit, it can be difficult to find the right size once the print wears off. Many brands on our list etch the sizes into the steel, while others use ink that rubs off after a few uses. Many cases also have the bit size printed inside so you know which bit to use. While not as essential as hard steel, accessories like a durable storage case make it a lot easier to transport the bits and keep them rust and corrosion-free. Harder steel will allow you to get more uses out of your tool, and we tried to point out any brands that use substandard steel on our list. Steel HardnessĮxtractors are not nearly as durable as most of your other tools, because unlike them, the extractor must bite into the steel bolts and screws, which often damages the tool as well. Most of the bolt extractors on this list are for bolts between ¼ and 1-inch. If you require these tools often, you may want to get one of the larger sets to prepare for any emergency. The size of extractor you need will depend on what size bolt or screw you are trying to remove. There is no need to hit it hard, which could damage the bit. When tapping in the bit, only use light taps with a small hammer to seat it.Patience is key! It would be best to treat extracting as a delicate surgical operation for the best chance of success.

Applying too much torque can cause the extractor to slip, ruining your extracting chances and possibly damaging the bit.

Though many extractors say you can use them with pneumatic and electric tools, we recommend an ordinary wrench or manual socket so you can gently coax out the offending bolt or screw.Screw extracting pliers are the least versatile tool because it only works on screws that are not flush with the surface, and the metal jaws must be extremely hard not to wear down when extracting in this way. Clampdown on the sides of the head of the stripped screw and twist until the screw comes out. They will require the screw to be sticking up from the surface far enough to grab the head’s side but are a single step extractor. Screw extracting pliers are exactly what they sound like-a pair of pliers with specially designed jaws to remove stripped screws. The third step requires gently twisting the extractor with the drill or a pair of pliers to remove the screw.The second step requires you to tap the extractor into the hole you created with a small hammer to get the bit started.Many of the tools on our list have a two-sided bit that features a drill bit on one side and the matching extractor on the other. The second step requires drilling into the surface to create a small hole the same diameter as the extractor you intend to use.The first step requires marking the center of the bolt or screw with a center punch.After enough screws, there will be sufficient damage that it will no longer grip tightly, allowing it to slip as you turn it, leaving the screw in place.

Each screw that you clamp down on to extract will leave a permanent mark on the tool. We loved the name and found the uniquely shaped jaws perfectly suited to removing stripped screws, but the problem we had with the VAMPLIERS was that the high carbon steel is not hard enough. It also has a tamper-proof sheath to cover the jaws when not used to protect them from damage and corrosive elements. It uses high carbon steel and an ergonomic handle with spring resistance to ensure smooth operation and optimal leverage. The jaws also open quite wide, and you can theoretically remove screws almost 2-inches wide if you were able to get enough torque. VAMPLIERS VT-001 Screw Extraction Pliers is a unique extraction tool that resembles an ordinary pair of pliers but with both vertically and horizontally serrated jaws designed to bite into and grip stripped screws tightly so you can extract them.
