Firstly, let's explore what a washer is: it is a thin flat disc-like object that is placed under the head of the bolt or nut. It prevents the nut or bolt head from rubbing against the surface of the material that is being assembled, which could cause it to weaken over time. It is typically made of metal or rubber and assists in preventing corrosion, reducing friction and distributing the load evenly.
The use of nut bolt washers is crucial for several reasons. Firstly, they help to distribute the load evenly across the surface of the material being assembled. This prevents the bolt or nut head from sinking into the surface and reduces the likelihood of the material cracking or breaking over time. Secondly, washers help to prevent the bolt or nut from loosening over time with everyday use or vibrations. This is because the washer adds an extra layer of friction, which helps to keep the bolt or nut firmly in place. This is especially important when working with moving parts or components such as wheels, machines and more.
Furthermore, washers are also important for reducing the risk of corrosion. The washer provides an extra layer of insulation between the nut or bolt head and the surface of the material being assembled. If left unprotected, these areas can become a breeding ground for rust and other forms of corrosion. This can weaken the structure over time and make it prone to failure. By using a washer with your bolt or nut, you can help to prevent this from occurring, thereby extending the lifespan of your projects.
Another major benefit of using washers with nuts and bolts is that it significantly reduces the amount of galling that occurs during the fastening process. Galling refers to the friction that occurs when two metal surfaces come into contact with each other. Over time, this can cause the surfaces to seize up and even break apart. However, by using a washer, you can significantly reduce the amount of galling that occurs, which helps to keep your assemblies tightly fastened together and reduces the risk of breakages and damages.
In conclusion, using washers with nuts and bolts is an essential part of any successful project. They work to improve the overall safety and durability of your project, by distributing loads evenly, preventing corrosion, reducing friction and providing an extra layer of insulation. This reduces the risk of damage, breakages and other issues that can lead to serious problems down the line. So next time you are working on a project that requires nuts and bolts, don't forget to use a washer – your project (and your wallet) will thank you for it!
