With a myriad of industries relying on fasteners to secure part types and machinery, there are countless types of fasteners available on the market. These include nuts, bolts, screws, and all of their subtypes of specialized designs, such as the focus of this blog: sealing fasteners. Sealing fasteners are unique in their ability to protect contaminants from entering a system. With high-tech properties and reliability across many applications, sealing fasteners are a staple of the military and aerospace sectors, finding use in fuel pumps of jet and rocket engines, satellite equipment, and more. For your better knowledge, we will explore the functions of these specialized fasteners and some examples of typical use.
 
Sealing fasteners can be any type of fastener, meaning a nut, screw, bolt, or other fastener type may contain the parts needed to perform a sealing function. The working principle of sealing relies on the use of a rubber O-ring part type or other rubber element, typically situated in the groove under the head of a screw or the face of a nut.  When squeezed, this element permanently seals out contaminants. This reliable seal protects against both solids and fluids, keeping applications safe from disinfectants, oil, gas, humidity, dust, moisture, debris, or chemicals. Furthermore, fastener seals also prevent the leakage of toxins out of machinery and devices into the surrounding environment.
 
The rubber component of sealing fasteners are the key to their fool-proof design. Although other rubber components are occasionally used, an O-ring is typically squeezed to provide a 360 degree hermetic seal. Under the head of a screw or related part, the O-ring sits in a groove so it is surrounded by metal on all sides, prolonging its life under pressure and ensuring it will not crack or break. Both the metals and rubbers used in sealing fasteners vary by intended use. For example, silicone rubber is popular for its ability to withstand temperatures ranging from 62° to 204° C, while a Buna-N compound is better for applications that require petroleum resistance.
 
Sealing fasteners are beneficial for applications where components must withstand harsh weather conditions and extreme atmospheres and temperatures. For this reason, they are also reliable components for military and aerospace applications. Military-grade sealing screws and O-rings that meet the requirements of the Military Standard Parts MS3212/MS3213/NASM 82496 and are pressure-tested to 1500 psi are available through select manufacturers. Additionally, they are made from corrosion-resistant materials, making them easy to clean. As such, they are often used in medical applications, ranging from laser scopes and surgical robots to kidney dialysis machines. Sealing fasteners also find home in a variety of other high-demand applications, including those with exposure to Arctic temperatures and electricity.

In the world of fasteners, nuts are one of the most common types of hardware used for assembly. Typically, nuts are paired with a correlating screw or bolt, twisting onto the tail-end of the component to hold two or more objects together with compression. Depending on the application in question and the types of materials being used, there are a number of nut types that one may take advantage of. One notable option is the wing nut fastener, that of which is distinguishable by its large metal wings that extend outward from the circular component. Wing nuts are popularly used in applications where tightening and removal are done by hand, and they are used in projects small and large. To help you determine whether the wing nut is the right type of fastener for you, we will discuss its characteristics in more detail!

A fastener is a device used to mechanically connect two objects. Examples include screws, nails, nuts, bolts, washers, anchors, and rivets. They are not permanent in that they can be unscrewed, loosened, and taken apart. The advantage of fastening two objects together rather than welding them is that the separate components can be replaced and maintained more easily. Different fasteners provide different amounts of strength, but there is also more to consider when purchasing fasteners for varying applications.

Fasteners are required to build everything. From bridges to garments, you can find them in every industry vertical. That being said, there are several types of fasteners and even more tools used in creating and securing them. Moreover, it is incredibly important to choose the correct tool for installation as well as the ideal fastener for your application. The use of an incorrect tool is a safety concern and can result in insecure attachment or a damaged fastener.

Fasteners are hardware components that may be used to conjoin parts for assemblies and to distribute loads. Threaded fasteners in particular are extremely common to countless applications and industries, and they are often discernible by a spiraling thread that trails down a cylindrical shaft. With this configuration, such fasteners can ensure more secure connections that are established by applying torque to the component. As there are many threaded fastener types available, each with their own characteristics, being aware of the most common types can be useful when searching for an optimal fit.

A hook and loop fastener, commonly known as velcro due to the Velcro brand name, is a fastener consisting of two linear fabric strips attached to the opposing surfaces to be fastened. The first layer of fabric is covered with tiny hooks, and the second is covered with tiny loops. Resins on the hook and loop fastener offer a secure connection, but one that is still easily removable. They are used in a broad range of industries such as aircraft, automotive, and industrial, as well as applications pertaining to clothing materials, supplies, and consumer products. In this blog, we will take an in-depth look at hook and loop fasteners.

A turnlock fastener is a type of fastener used to secure inspection plates, doors, and other removable panels on an aircraft. Also known as quick-opening, quick-action, and stressed panel fasteners, they are noted for their quick and easy removability for inspection and servicing purposes. The most common types of turnlock fasteners are Dzus, Camloc, and Airloc. In this blog, we will discuss all three and their unique characteristics.

Bolts are important fastener types for a number of commercial and industrial assemblies, allowing for robust connections that can handle shear and tension forces. For installation, a standard bolt is passed through holes of components, and it is then paired with a nut to provide a permanent fastening solution through compressive force. While bolts may provide strong assemblies for a number of applications, certain areas may prove difficult for making connections such as when one side of the assembly cannot be accessed. With a blind bolt fastener, affixing components in hard to reach areas becomes much easier, all while ensuring a strong, lasting joint.

Fasteners can be found, used, and applied in a variety of fields, ranging from industrial to manufacturing to the military and in business. Fasteners literally make up and contribute to the foundation that holds many of the buildings and mechanisms that we use every day. And while fasteners are very common, there are many distinct variations, the differences of which are important to understand (particularly for those working in aviation manufacturing and in the supply chain sectors). To put it simple, a fastener refers to a type of mechanical component used to fasten or tighten two or multiple pieces so as to form one cohesive piece. Fasteners can be applied on many different items including machinery, equipment, vehicles, ships, railways, bridges, etc. The different types of fasteners are categorized by performance, specifications, serialization, etc. In this guide, we will explore a few basic types of fasteners.
