All About Bolts

Though bolts are simple threaded fasteners, they are indispensable in applications ranging from assembling furniture to constructing massive buildings and bridges. When used with components like nuts and washers, bolts serve to reliably secure materials and structures together. In this blog, we discuss various different types of bolts and their specific uses to assist in selecting the right one for any given task.

A typical bolt consists of two main parts: the bolt head and bolt shaft. The bolt head is the top part of the bolt that can be grasped with a tool, such as a wrench or socket, to tighten or loosen the bolt. Meanwhile, the bolt shaft is the cylindrical part of the bolt that is threaded, which allows the nut to be turned and tightened against the bolt head for a secure hold. Bolts come in various sizes, materials, and designs, each being tailored for specific applications.

Common Types of Bolts and Their Uses

For example, one of the most common types of bolts are hex bolts, which are more formally known as hexagon head bolts. These bolts have a hexagonal head and are widely used in construction and machinery due to their strength and ease of use. For the next common type, carriage bolts are characterized by a rounded head with a square neck that prevents the bolt from turning once installed. Because of their snug fit and smooth head, these bolts are often used in wood connections for a finished appearance, such as in decking and fence building.

As another noteworthy variant, lag bolts are essentially large wood screws that have a hexagonal head. When driven into heavy materials like wood or steel with a wrench, lag bolts provide a strong and sturdy hold. Eye bolts are one that are more set apart from other variations, a result of being designed with a loop or eye at one end instead of a traditional head. Such bolts are used for attaching cables, ropes, or chains, and they are particularly common in applications that require lifting or securing loads.

Bolt Effectiveness with Nuts and Washers

No matter the type, bolts are often paired with components like nuts and washers to enhance their effectiveness. Nuts are a type of threaded fastener that, when tightened onto a bolt shaft, clamp the materials between the bolt head and themselves to create a strong joint. There are various types of nuts, such as hex nuts, lock nuts, and wing nuts, each designed for specific purposes. Hex nuts are the most common, being hexagonal in shape and used in a wide range of applications, while lock nuts have a nylon insert that prevents them from loosening due to vibration.

On the other hand, washers are thin, flat discs with a hole in the center. When placed between the bolt head or nut and the material being fastened, washers serve to distribute the load over a larger area, reducing the risk of damage to the material and ensuring a more secure connection. There are different types of washers, including flat washers, lock washers, and fender washers. Flat washers are the most basic type, simply serving to provide a smooth surface, while fender washers have a larger diameter to provide extra surface area for distributing the load. Alternatively, lock washers are designed with teeth to further assist with preventing bolts and nuts from loosening.

Conclusion

In summary, bolts are essential fasteners in the realm of construction and engineering for securely joining materials together. Whether it is hex bolts for general construction, carriage bolts for wood connections, lag bolts for heavy-duty fastening, or eye bolts for lifting applications, each type of bolt serves as vital to the security of assemblies.
