A seal for use in a ball screw assembly sealingly engages portions of both the nut and the screw. The seal has a plurality of teeth at an outer peripheral surface, and further has a seal thread received in a thread on the screw. The seal is rotated relative to the nut and moves axially due to the screw thread until a seal face sealingly engages the nut. A set screw is then inserted through the nut, into a space formed between adjacent teeth on the seal, to prevent further relative rotation of the seal and the nut. A force from the nut on the seal urges the seal axially such that the seal thread is biased into the screw thread, providing sealing contact between the seal thread and the screw thread.
