how select all washer
only select all washer
In the case you posted, you could turn the model so you're looking at it from the side (the edge of the plate), then use a click and drag box (left to right) to select only the washers.
For this one, I would use Glenn´s method. If you had a lot of them all over a bigger assembly I would use the filter in the design tree. 2012 SOLIDWORKS Help - Filtering the FeatureManager Design Tree in Assemblies
Use SOLIDWORKS Power Select to select the washer (this works great in larger assembly and specially when washers are placed at different locations). You can save the criteria in case you need to select them again.
