Flat washers are used under bolt heads or nuts to increase the bearing area or offer greater hardness, so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a nut or bolt.
- Flat washers are used in applications requiring a bearing surface for fasteners to minimize surface wear, as well as, evenly distributing fastener loads to minimize surface deformation when the fastener is tightened
- They are, also, used to cover large clearance holes
- Metallic flat washers can conduct electricity and provide more compression strength than non-metallic flat washers
