1. A lock bearing for a points setting configuration, the locking bearing comprising: a lock bearing screw penetrating a foot of a setting tongue and said lock bearing screw having a hexagonal head; a safety plate for rotationally fixing said lock bearing screw, said safety plate having a hole formed therein, said hole having a profile matching said hexagonal head, said hole for latching in place over said hexagonal head and rotationally fixing said lock bearing screw when said hexagonal head is brought into alignment with said hole profile; and a spring package disposed between the foot of the setting tongue and said head of said lock bearing screw, said spring package providing a rotation reserve for rotationally bringing said hexagonal head into alignment with said hole profile while maintaining a definable torque range for preventing said lock bearing screw from introducing impermissible tensions into the locking bearing.
