DIN 6319 spherical washers are used for clamping on non-parallel surfaces. These are sold individually not as sets. Refer to spec sheet for corresponding spherical washer selection.

GN 350.3 features two spherical washers that are used together and cannot be detached from each other. The load bearing capacity of these spherical washers is relatively high. This is not only due to the material quality but also to the matched curve of the concave washer. Height is 13/16". Static Load is 111280 lbf.

Spring Washers compress to act like a spring and deflect when loaded, providing a preload between the two joined surfaces. Fasteners are used where assemblies need a part to eliminate rattle, maintain assembly tension, compensate for expansion or contraction, or to absorb intermittent shock loads for long lasting durability.
