A broken bolt can be a frustrating and time-consuming problem to solve. Whether you’re working on a car engine, a piece of machinery, or just a household item, a broken bolt can stall your progress and prevent you from completing the task at hand. Fortunately, there are several techniques you can use to remove a broken bolt and get back on track. Here’s a look at some of the most common methods.
Method 1: Using a Drill and Tap Extractor Set
The simplest way to remove a broken bolt is to use a drill and tap extractor set. This set includes a drill bit and a tap extractor that can be used together to remove the broken bolt. Here’s how to do it:
Step 1: Drill a hole in the center of the broken bolt using the drill bit.
Step 2: Insert the tap extractor into the hole and turn it counterclockwise.
Step 3: Continue turning the extractor until the broken bolt is removed.
Method 2: Using a Left-Handed Drill Bit
The first method doesn’t work, you can try using a left-handed drill bit. This type of drill bit rotates in the opposite direction of a regular drill bit, which can help to loosen the grip of the broken bolt. Here’s how to use a left-handed drill bit:
Step 1: Center the drill bit on the broken bolt and start drilling in a counterclockwise direction.
Step 2: Continue drilling until the broken bolt begins to loosen.
Step 3: Use pliers or a wrench to remove the broken bolt from the hole.
Method 3: Using a Bolt Extractor
If the first two methods fail, you can try using a bolt extractor. This tool is designed specifically for removing broken bolts, and it works by gripping the broken bolt and turning it counterclockwise. Here’s how to use a bolt extractor:
Step 1: Place the bolt extractor over the broken bolt and tighten the screw until it grips the bolt.
Step 2: Turn the extractor counterclockwise until the broken bolt is removed.
Step 3: If the bolt extractor does not work, try using penetrating oil to help loosen the grip of the bolt.
Method 4: Using a Torch
Another technique for removing a broken bolt is to use a torch. The heat from the torch can help to expand the metal surrounding the broken bolt, making it easier to remove. Here’s how to use a torch:
Step 1: Place the torch over the broken bolt and heat the area until it is red hot.
Step 2: Allow the metal to cool for a few minutes.
Step 3: Use pliers or a wrench to remove the broken bolt.
Cutting The Broken Bolt With A Hacksaw
If you’re looking for a quick and easy solution to remove a broken bolt, using a hacksaw may be the answer. It is one of the oldest methods to remove a broken bolt, but it still works. All you need is a hacksaw with a fine-tooth blade, some lubricant, and the right technique.
To start, place the hacksaw blade against the broken bolt and use firm pressure to start sawing away at it. It wants to move the blade up and down with long strokes so that you don’t overheat the metal. As you go, use a lubricant to help keep the blade from getting stuck and to reduce friction on the metal. Once the bolt has been cut off, it should come out with ease.
Using a chisel and hammer
Removing a broken bolt with a chisel and hammer is an effective method that requires you to be precise with your hammer strikes. It will need to place the chisel tip on the head of the broken bolt and carefully hit it with a hammer. The shock of the strike will cause the bolt to break and come off easily.
When hitting the bolt, make sure to angle your chisel downward so that it drives the head down and out of the hole. After a few blows, the broken bolt should be free. Be careful to not overstrike the bolt, as this can damage the surrounding material or even cause further breakage of the bolt itself.
When using a chisel and hammer, it’s important to wear protective eye gear and gloves, and use a face shield if available. Taking precautions to protect yourself is crucial when working with chisels and hammers. You should make sure to hold your chisel at a 90-degree angle to the surface for maximum power.
It’s also important to ensure that your hammer isn’t too heavy, as this can cause damage to the workpiece or break the bolt completely. With a steady hand and precise technique, you should be able to successfully remove any broken bolts with ease.
Welding a nut onto the broken bolt
Welding a nut onto the broken bolt is a good way to remove a broken bolt, but it is important to make sure that you have the right safety equipment and the proper skill level to do so. This method involves taking a nut that fits the thread of the broken bolt and welding it on top of the bolt.
The idea is to then use a wrench to unscrew the nut and pull out the broken bolt with it. This method can be difficult and dangerous if not done correctly, so it is important to make sure you have the necessary safety equipment before attempting this method.
When welding a nut onto a broken bolt, there are a few key things to keep in mind. Make sure the nut is tight against the broken bolt and properly welded in place. Once that is done, you will need to use an adjustable wrench to turn the nut and remove the broken bolt.
Be sure to work slowly and carefully so as to not cause any further damage. It will be sure to clean up any debris or sparks that come from the welding process. Taking these precautions will ensure that you get the broken bolt removed safely.
Using an impact wrench
If the bolt is still stuck in place, you can try using an impact wrench. An impact wrench uses high-torque force to help break the bond between the bolt and the material it’s stuck in. Its uses an impact wrench, attaches a socket head to the end of the wrench, and lines it up with the broken bolt.
Then, turn on the power and apply pressure to the handle. The impact wrench should break the bond and allow you to easily remove the broken bolt.
However, keep in mind that an impact wrench isn’t always the best solution for removing a broken bolt. its high-torque force of the wrench can cause damage to the surrounding material, so be sure to use it carefully and make sure to wear protective gloves and eyewear to protect yourself from any flying debris.
