Removing rusted bolts can be a real pain in the neck, especially if you don't have the right automotive tool for the job. As an automotive tools supplier, I've seen firsthand the struggles that mechanics and DIY enthusiasts face when dealing with these stubborn bolts. In this blog, I'll share some of the best tools for removing rusted bolts and give you the lowdown on why they work so well.
Penetrating Oil
Let's start with the basics: penetrating oil. This stuff is like magic when it comes to loosening up rusted bolts. Penetrating oil works by seeping into the tiny spaces between the bolt and the nut or the threaded hole. It breaks down the rust and corrosion, reducing friction and making it easier to turn the bolt.
One of the most popular penetrating oils on the market is WD - 40. It's widely available and does a decent job of loosening rusted bolts. However, for more stubborn rust, you might want to go for a heavy - duty penetrating oil like PB Blaster or Liquid Wrench. These oils are formulated to be more effective at cutting through thick rust and corrosion.
To use penetrating oil, simply spray it generously on the rusted bolt and let it sit for a while. The longer you let it penetrate, the better. Sometimes, it can take several hours or even overnight for the oil to work its magic. After the waiting period, you can try to turn the bolt with a wrench.
Impact Wrench
If the penetrating oil doesn't do the trick, it's time to bring out the big guns: the impact wrench. An impact wrench is a powerful tool that delivers a high - torque, sudden rotational force to the bolt. This force can often break loose even the most stubborn rusted bolts.
There are two main types of impact wrenches: pneumatic and cordless. Pneumatic impact wrenches are powered by compressed air and are typically more powerful than cordless ones. They're a popular choice in professional auto repair shops. Cordless impact wrenches, on the other hand, are more convenient and portable. They're great for DIYers who don't have access to a compressed air system.
When using an impact wrench, make sure to use the right size socket for the bolt. Also, be careful not to over - torque the bolt, as this can cause it to break.
Bolt Extractor
Sometimes, the bolt head might be so rusted or damaged that you can't get a good grip on it with a wrench. In this case, a bolt extractor is your best bet. A bolt extractor is a tool that's designed to grip the inside of the bolt and turn it out.
There are different types of bolt extractors, such as spiral - flute extractors and square - drive extractors. Spiral - flute extractors work by biting into the inside of the bolt as you turn them counter - clockwise. Square - drive extractors, on the other hand, fit into the square - shaped hole in the center of some bolts.
To use a bolt extractor, you first need to drill a hole in the center of the bolt. Then, insert the extractor into the hole and turn it counter - clockwise with a wrench or a drill.
Heat
Applying heat is another effective method for removing rusted bolts. When you heat a bolt, it expands. As it cools, it contracts, which can break the bond between the bolt and the rust.
You can use a propane torch to heat the bolt. Make sure to heat the bolt evenly and avoid over - heating it, as this can damage the surrounding parts. After heating the bolt, let it cool down for a few minutes and then try to turn it with a wrench.
Other Tools to Consider
While the above tools are the main players in removing rusted bolts, there are a few other tools that can come in handy. For example, a Multifunctional Staple Gun might not seem like an obvious choice, but it can be used in some creative ways. You can use it to hold parts in place while you work on removing the bolt.
A Cordless Drill and Screwdriver is also useful. You can use it to drill out the bolt if all else fails. And a Folding Saw can be used to cut through a bolt if it's accessible and you don't mind sacrificing the bolt.
Conclusion
So, which automotive tool is best for removing rusted bolts? Well, it depends on the situation. Penetrating oil is a good first step, as it's easy to use and relatively inexpensive. If that doesn't work, an impact wrench or a bolt extractor might be your next options. Heat can also be effective in some cases.
