Washers are small flat disks used for various purposes of fastening, adjusting, and distributing forces in different applications. They are commonly employed in mechanical, hydraulic, and electrical fields.
Washers are used for several purposes, including:
- Fastening: Washers can be used together with screws, bolts, or nuts to distribute the clamping force and protect the contact surface. They help prevent the applied force from damaging materials or causing bolts to loosen.
- Leveling: Washers can be used to compensate for misalignments or irregularities on supporting surfaces. They allow for a better distribution of the load and ensure a uniform application of force.
- Electrical insulation: Insulated washers are used to create an electrically insulating interface between components. This prevents the passage of electrical current between metal parts, reducing the risk of short circuits or interference.
- Vibration reduction: Anti-vibration or damping washers are used to reduce vibrations and the loosening effect caused by oscillations. These washers are often made of elastic materials or have specific geometries to absorb vibrations.
Washers can come in various types and sizes depending on the specific application. The choice of washer type depends on the fastening needs and the type of load it will be subjected to.
