Hex Head Fasteners and the Wrenches Needed to Loosen Them


Hex head fasteners, also known as hex bolts, are a type of fastener that has a hexagonal head with six sides. These bolts are commonly used in all kinds of machinery, from automobiles to construction equipment to industrial machines. However, when it comes time to repair or maintain these machines, you need to know the right tools to use. In this article, we'll explore the types of wrenches that are used to loosen hex head fasteners.


What Are Hex Head Fasteners?


Before we dive into the types of wrenches you'll need, it's important to understand what hex head fasteners are and their importance. Hex head fasteners are a type of bolt that uses a hexagonal head to provide a secure grip. These bolts are used in a wide range of applications, from furniture and household appliances to automotive and heavy machinery.


Due to their versatility and strength, hex head fasteners are a go-to choice for many different types of construction and repairs. However, the hex head design requires a specific type of tool to loosen and tighten them effectively.


Types of Wrenches to Loosen Hex Head Fasteners


1. Hex Wrench: The most common type of wrench used to loosen hex head fasteners is a hex or Allen wrench. This wrench has a hexagonal shape that matches the shape of the bolt head. Hex wrenches come in a variety of sizes to fit different bolt sizes, from small furniture bolts to larger industrial bolts.


2. Socket Wrench: Another type of wrench commonly used to loosen hex head fasteners is a socket wrench. A socket wrench comes with a set of sockets of different sizes that fit onto the end of the wrench. To use this tool, you need to attach the socket that matches the size of the hex head bolt you're working with. Socket wrenches are ideal for removing hex bolts in hard-to-reach places.


3. Combination Wrench: A combination wrench is a versatile tool that can be used to loosen many different types of nuts and bolts, including hex head fasteners. This wrench has an open-end side for easy access to bolts and a closed-end side for additional leverage. Combination wrenches come in various sizes and styles, making them useful for a wide range of applications.


4. Adjustable Wrench: An adjustable wrench, commonly known as a crescent wrench, is useful for loosening hex head fasteners of different sizes. This wrench has a sliding jaw that can be adjusted to fit the size of the bolt head. Adjustable wrenches are convenient when you don't have access to several different-sized wrenches, but they may not provide the same level of torque as a specialty hex head wrench.


5. Spanner Wrench: A spanner wrench is a specialized tool designed specifically for use with hex head fasteners. This wrench has a unique shape, with two curved jaws that grip the bolt head on opposite sides. Spanner wrenches provide a secure grip on hex bolts, reducing the risk of rounding off the corners. These wrenches come in different sizes to fit various bolt sizes.


In conclusion, when dealing with hex head fasteners, you need to use the correct tools to do the job right. The type of wrench you choose will depend on the size and location of the bolt you're working with. Whether you use a hex wrench, socket wrench, combination wrench, adjustable wrench or spanner wrench, make sure you're using the right tool for the job to get the best results.
