Type by purpose

A washer is a type of fastener that is placed under the head of another fastener (screw, bolt, self-tapping screw, screw), or under a nut in order to create a large supporting surface area to prevent the part from self-unscrewing. The washer is used if the contact area of the adjacent surface of the bolt head (or nut) with the surface of the part is insufficient or if there is a risk of damage to the material of the part. A washer is a popular type of fastener that acts as a seal when connecting. It is designed for fixing bolts, screws, nuts, studs or other fasteners.
