Mechanical requirements for the fastener parts include a minimum buckle pressure of 18 kN per set. Additionally, each set of fasteners should exhibit a longitudinal resistance of not less than 9 kN on the rails. The fastener system is expected to withstand 3 million load cycles without damage, and the gauge length should be limited to less than 6 mm after the specified cycles. Single rail adjustments include left and right positioning within the range of -8 to +6 mm, gauge adjustment within -16 to +12 mm, and rail height adjustment of 10 mm. These specifications ensure the durability, stability, and operational reliability of the fastening system under various conditions.
