An end retention system (3) for a rolling shutter system is provided. The end retention system (3) comprises a fastener (8) that has a head (21) and a shaft (12, 14), and a washer (9) that has an outer diameter and an aperture (11) having an inner diameter. The inner diameter of the aperture (1 1) of the washer (9) is at least twice the diameter of the shaft (12, 14) of the fastener (8). The shaft (12, 14) is configured for insertion into a screw boss receptacle (10) of a shutter slat (1). The end retention system (3) may also comprise a guide track (43) that has retention fins (46) spaced apart a distance (27) that is less than the outer diameter of the washer (9). The guide (43) may include a channel (48) that partially bounded by the retention fins (46). The channel (48) may have a width that is greater than the outer diameter of the washer (9). The washer (9) is located in the channel (48), and is retained near the slat (1) by the head (21) of the fastener (8). |
