The end retention system comprises a fastener that has a head and a shaft, and a washer that has an outer diameter and an aperture having an inner diameter. The inner diameter of the aperture of the washer is at least twice the diameter of the shaft of the fastener. The shaft is configured for insertion into a screw boss receptacle of a shutter slat. The end retention system may also comprise a guide track that has retention fins spaced apart a distance that is less than the outer diameter of the washer. The guide may include a channel that partially bounded by the retention fins. The channel may have a width that is greater than the outer diameter of the washer. The washer is located in the channel, and is retained near the slat by the head of the fastener.
