Rail fastener and arrangement comprising such a rail fastener
A rail fastener (7) comprises an anchoring shaft (9) for fixing the rail fastener (7) in a fastening base, for instance a sleeper (2) which bears the rail (1), and a head (10) which is integrally formed on the anchoring shaft (9) and equipped with means for receiving a torque for the purpose of screwing the anchoring shaft (9) into the fastening base. The rail fastener (7) is distinguished in that—a threaded shaft (11) is integrally formed on the head (10) on the side thereof opposite to the anchoring shaft (9) or a bore equipped with an internal thread is made in the head (10) and/or the anchoring shaft (9) integrally formed thereon from the side thereof opposite to the anchoring shaft (9), —the head (7) has a surface portion as a first abutment surface (24) annularly surrounding the threaded shaft (11) or the threaded bore, —the rail fastener (7) has a clamping element (12) seated on the threaded shaft (11) or engaging in the internal thread of the head (10) and/or of the anchoring shaft (9) and meshing with the respective thread, which clamping element has an outwardly projecting projection for supporting on at least one leg of a rail hold-down spring (22) and a shaft portion (15) integrally formed thereon in the direction of the head (10), which shaft portion has a second abutment surface (26) directed towards the head (10) and corresponding with the first abutment surface (24) and—between the two abutment surfaces (24, 26) there is situated a securing disc or a securing disc arrangement (16) which is supported on the abutment surfaces (24, 26) to prevent the clamping element (12) from loosening.
