DIN6796 washers are used in a variety of applications across virtually every industry that maintains bolted connections. The washer is not an insignificant engineering contribution—by combining washers in stacks or series or including them in other bolt assemblies, longer service life, lower maintenance and high levels of equipment dependability and safety are realized.

Q: Should one or two washers be used on a bolt?

A: Depending on the application about 90% of the time, the most common bolting arrangement is to have one piece on each side of the joint. On the other hand, there are many applications where a single washer adds enough elasticity to the system. Conversely, there are other situations where three or more washers may be needed for a sound design.
