摘要： The retention value of a screw previously inserted into a wooden railroad tie is increased by an axially extending sleeve ( 20 ) having an external thread ( 24 ) and an internal thread (25). The thread revolutions of the internal thread (25) are offset axially by half (h) the thread pitch (H) of the external thread (24). Due to this offset of the threads, the screw is positioned in the sleeve so that its threads are located between the external thread revolutions affording a new retention, while the external thread (24) seats within the thread previously formed in the wooden railroad tie by the screw.

摘要： A substantially cylindrical washer having two arch-shaped channels 7, on a face on the bore hole side of the washer, wherein said channels connect an opening 2 with a through passage 3. The opening 2 is configured for the passage of an anchor rod and the through passage 3 is configured for filling a mortar mass into the bore hole. The channels 7 open relative to the bore hole and include a substantially semi-circular cross-section to assure the high tensile strength of the washer.
