Washers are usually flat, usually disk like with a hole in the middle of it and are used to help distribute the load of a threaded fastener such as a bolt or nut. Available in steel, brass, copper, plastic and even rubber, the type to be used depends on the application and the environment

Washers are used for such purposes as one of the major tasks of a washer is to spread the load in a uniform manner. When a bolt is tightened, the force is applied to a small area on the head and the threads part of the bolt. Under this pressure, if there is no washer, the material may get deformed or even fail to hold the pressure. Washers dispersed this force over a larger area and therefore any point could not be subjected to high stress that could lead to damage. This is more so in assemblies where some of the materials used are soft such as wood or plastic since they are more likely to get crushed under pressure

Vibration or dynamic load in any assembly creates a potential problem of fastener loosening over time. This is where washers come to the rescue The objective of this article is to help the reader understand how washers make life easier during washing. There are special washers like split washer or tooth washer which are especially used to avoid the loosening. They develop a sort of a spring like action, providing a constant force that tends to resist the tendency of vibrations and dynamic forces that tend to cause the parts to become loose. This way, the assembly is kept tight and secure, thus increasing the lifespan and safety of the structure

Washers also have a protective function as they prevent the deterioration of the items they come across. If a washer is not used when a fastener is tightened then the turning motion will actually scratch and wear the surface. This, in the long run, causes corrosion and a weakening of the material used to make the object. The washer is placed between the fastener and the surface, it absorbs the friction while the material of the surface is protected

It is also important to note that the kind of washer that is used can greatly improve the function of the fastener. For instance, a flat washer offer a flat surface on which another object can rest on, this is important when controlling the torque when tightening. This means that the fastener can be tightened up to the right tension than the required level of force, thus making the assembly to be more reliable and consistent. Furthermore, the type of washers to be used should be of the right hardness and material to avoid galling and seizing that are usually associated with some metals

In assembly where electrical components are used, insulating washers may be very essential. These washers are normally made of non-conductive material such as plastic or rubber to ensure that electrical currents cannot flow through the fastener hence no short circuiting and other electrical problems. This is especially crucial in electronics and electrical appliances and devices where the insulation of the electrical circuits is crucial for the effective and safe operation of the gadgets

Washers are very flexible and can be designed to the customer’s specification. There are many types of them in terms of shape, size, and the material used in their construction for various uses. For example, fender washers have a larger outer diameter and are used when thin or soft materials are used. Conical washers also known as Belleville washers are characterized by high load bearing capability and are preferred for applications where high spring tension is needed. This versatility makes washers a necessity in a broad area of applications including construction, automobile, aerospace, electronics among others

At Alloyed Sustainables, we are committed to promoting sustainable practices in every aspect of our operations. Washers contribute to sustainability by extending the life of assemblies and reducing the need for frequent replacements and repairs. By preventing damage and loosening, they help maintain the structural integrity and functionality of assemblies for longer periods. This not only reduces material waste but also lowers maintenance costs, offering economic benefits as well

In the grand scheme of any assembly, washers may seem like minor components, but their importance cannot be overstated. They play a crucial role in load distribution, stress reduction, preventing loosening, protecting surfaces, enhancing fastener performance, providing electrical insulation, and offering customization and versatility. Moreover, their contribution to environmental and economic sustainability aligns perfectly with the values we uphold at Alloyed Sustainables
