A rail fastening device (10) comprises a clip 16 and a washer (17) for fastening to a rail support (12) by an upstanding bolt 14 having a nut (15), which can be tightened to lock the device (10) in position. The clip (16) and washer (17) comprise respective apertures (18), (19) for receiving the bolt (14). The washer (17) is adapted to rotate as the nut (15) is tightened until a formation on the washer (17) abuts an upstanding formation (24) on the rear of the clip (16) at point A, whereupon continued tightening of the nut (15) causes the washer (17) to pivot at point A around an offset axis, so as to bring the bolt (14) into contact with a front surface (18F) of the clip aperture (18). Further tightening of the nut (15) pivots the washer (17) to a point where any displacement force applied to the clip (16) by the rail is applied directly to the bolt (14) and not to the washer (17). In this manner, the risk of the washer failing, or bolt (14) bending is avoided.
