In the realm of aviation, engineering, and manufacturing, there is a critical yet often overlooked element that holds countless assemblies together: the fastener. These components play an indispensable role in ensuring the integrity, safety, and functionality of countless structures and machines that shape our modern world. From the towering skyscrapers that define our urban landscapes to the cutting-edge aircraft that soar through the skies, fasteners are the pivotal hardware elements that connect and secure components together, designed to withstand the daily rigors of operations and environments. In this blog, we will discuss the basics of fasteners, delving into their diverse types, applications, and their significance across the realms of aviation, engineering, and manufacturing.
At its core, a fastener is a device designed to join or hold two or more objects together in a permanent or semi-permanent fashion. One can think of them like the glue of the industrial world, ensuring that individual components are joined in a reliable manner. Depending on whether one needs to have a rigorous, permanent connection between metal surfaces or simply needs to secure papers together for a short amount of time, there is a myriad of fasteners that exist to accommodate various needs. Next, we will discuss the most common types of fasteners on the market and their popular uses, allowing you to have a good understanding of such hardware and what particular solution may be best for you.
Bolts and Nuts
Bolts and nuts are generally the most recognizable type of fasteners across markets, and they range in application from general-purpose assembly to industrial construction. Bolts are externally threaded rods with a head on one side, intended to have the tail end passed through a preformed hole of an assembly. Meanwhile, nuts are a type of fastener that feature holes with internal threading, allowing them to be tightened onto the end of a matching bolt to secure parts together. The combination of the two fasteners creates a reliable joint that can be easily tightened or loosened with simple tools, the threading keeping the fasteners together and the heads established on each side of the assembly ensuring that pieces cannot be pulled apart with ease. In industries such as construction and manufacturing, bolts and nuts are often used for assembling structures, machinery, and equipment.
Though often overlooked, even in the world of fasteners, washers are essential hardware components that distribute the load of a fastener and prevent damage to the surface it is tightened against. They come in various types, such as flat washers, lock washers, and spring washers, each serving a specific purpose in maintaining the integrity of connections. Alongside load distribution, many washers also perform roles such as acting as a spacer, spring, wear pad, locking device, or vibration reducer.
Screws are similar to bolts, featuring a head on one side and an externally threaded shaft. However, rather than being paired with a nut to secure parts or requiring a preformed hole, screws can often bore their own threading as they are driven into a material. Generally, screws are used for materials like wood and metal, and they provide exceptional holding power.
Rivets are permanent fasteners that are used to join two or more pieces of material through deformation. While coming in a number of types, a basic rivet will feature a smooth, cylindrical shaft and a head on one side, and they are designed to be inserted into a preformed hole. Once placed, a specialized tool is used to upset or deform the headless side of the shaft, creating a second head that secures the assembly parts together until the joint is manually broken. Rivets are a type of fastener that find use in industries like aviation and aerospace, where structural integrity is paramount. The riveting process ensures a tight and reliable bond, making it suitable for applications where welding or screwing might be less feasible.
Pins are common fasteners that come in various forms, such as dowel pins and cotter pins. Generally, pins are non-threaded, finding use in industrial machines, vehicles, electronics, infrastructure, and other assemblies where alignment and connection are paramount. Dowel pins in particular are used for the precise alignment of components, while cotter pins are commonly used to secure parts like wheel axles in machinery.
Clips and Clamps
When a more temporary connection is required to hold things together, clips and clamps are often the best choice. Often being easily installed and removed by hand, clips and clamps are used in manufacturing, automotive, and household applications, where frequent assembly and disassembly are required. While some clips may simply be used to hold a stack of paper together, others may even be used to secure the fuel hose of an engine. As such, they are quite diverse in their use.
