HIGH-QUALITY PRODUCTS
Washers are often used to optimize the assembly of parts when using threaded fasteners. They are used in assembly systems in various ways:
- to distribute a load over a greater surface area,
- to fasten the system in oval holes,
- to ensure electrical contact and/or compensate for axial play or creep.
