Loosening a very tight bolt can be a daunting task, especially if you don’t have the right tool for the job. Using the wrong wrench can cause damage to both the bolt and the tool, which can result in additional costs and wasted time. Therefore, it’s important to know which wrench to use when you encounter a tight bolt.
Types of Wrenches
There are many types of wrenches available on the market, but not all of them are suitable for loosening a very tight bolt. Here are some of the most commonly used wrenches:
- Adjustable wrench
- Socket wrench
- Open-end wrench
- Combination wrench
- Torque wrench
Which Wrench Should You Use?
The type of wrench you should use depends on the bolt’s size, shape, and location. Here are some guidelines to help you choose the right wrench for the job:
Adjustable Wrench
An adjustable wrench is a versatile tool that can be used for a variety of tasks. It has an adjustable jaw that can be tightened or loosened to fit different bolt sizes. However, using an adjustable wrench on a very tight bolt can be risky because it can slip or round off the bolt’s corners. If you have no other option but to use an adjustable wrench, make sure to grip the bolt as tightly as possible and apply pressure in the direction that loosens the bolt.
Socket Wrench
A socket wrench is a great tool for loosening a very tight bolt because it provides a secure grip on the bolt’s head. It comes in a variety of sizes, and you can choose the right size socket to fit the bolt’s head. Socket wrenches also come in different types, such as a ratchet wrench or a breaker bar, which can provide additional leverage for stubborn bolts.
Open-End Wrench
An open-end wrench is a simple tool that has a U-shaped opening on both ends. It’s ideal for use in tight spaces where there isn’t enough room for a socket wrench. However, using an open-end wrench on a very tight bolt can cause the wrench to slip or round off the bolt’s corners. If you have no other option but to use an open-end wrench, make sure to grip the bolt as tightly as possible and apply pressure in the direction that loosens the bolt.
Combination Wrench
A combination wrench is a versatile tool that has a box-end wrench on one end and an open-end wrench on the other end. It provides the benefits of both types of wrenches, making it a great tool for loosening a very tight bolt. However, using a combination wrench on a very tight bolt can cause the wrench to slip or round off the bolt’s corners. If you have no other option but to use a combination wrench, make sure to grip the bolt as tightly as possible and apply pressure in the direction that loosens the bolt.
Torque Wrench
A torque wrench is a specialized tool that measures the amount of force being applied to a bolt. It’s ideal for use when you need to tighten a bolt to a specific torque setting. However, it can also be used to loosen a very tight bolt by applying additional force. Torque wrenches come in different types, such as a click-type or beam-type, which provide different levels of accuracy and ease of use.
Conclusion
Loosening a very tight bolt can be a challenging task, but using the right wrench can make the job much easier. When choosing a wrench, consider the bolt’s size, shape, and location. A socket wrench is usually the best choice for loosening a very tight bolt, but other wrenches such as an adjustable wrench or a torque wrench can also be used depending on the circumstances. Always make sure to grip the bolt as tightly as possible and apply pressure in the direction that loosens the bolt to avoid damage to both the bolt and the tool.
