Washers are thin, usually flattened, disc or circular-shaped pieces of metal with a hole in the middle used together with threaded fasteners. While they are part of the assembly, they do not hold anything together or drive in surfaces. This article will discuss what washers are used for and why they are an essential component in various applications.
Distribution Of Load
Threaded fasteners such as nuts, bolts, and screws exert significant pressure on the surfaces they hold together. This force can cause damage or deform the surface, leading to cracks and weakening of the material. For example, driving a screw into a wood may create a hole too large for the screw to hold on to, thus compromising its strength.
Washers help distribute this load evenly over a larger area. This distribution reduces the pressure exerted on the surface and prevents damage.
Preventing Leakage
Fasteners pass through holes in the surfaces, getting held together. However, in some cases, such as piping, you need these holes sealed. Washers help create a tighter seal, preventing any leakage between the surfaces.
Such washers are often made of soft material that presses completely against the surfaces.
Reduce Vibration
In applications where the surfaces are prone to vibrations, such as in automotive or machinery, washers play a crucial role. They act as shock absorbers for the fasteners and prevent them from loosening due to constant movement.
Such types of washers are also known as vibration-isolating or vibration-damping washers. They consist of softer materials such as rubber, plastic, or urethane.
Alignment
In some applications, precision is crucial. If bolts or screws are not aligned correctly with their corresponding holes, it may cause misalignment of the entire assembly. Washers with an inner diameter larger than that of the fastener can act as shims and help align these fasteners correctly.
