The CableRack M6 Cage Nut and Screw kit includes the nut, screw and plastic washer as shown in the photo. These cage nuts are used in relay rack and four post racks with square holes (which is like 99% of rack systems). The screws are 12mm long, which is 2mm longer than most. The extra length is great when you're dealing with equipment that has thicker rack ears or you just need the extra length to make everything fit. The plastic washers are a nice touch, when you don't wish to turn the screws directly against the rails which often scrapes off the factory powder-coat.
