This lock nut secures the wiper shaft in the body panel of the vehicle. The product fits classic Citroën models such as 2CV and DS. The nut provides a stable connection between wiper shaft and body, so the wiper can move across the screen without unwanted play. The dimensions match the standard fitment of the wiper shaft. The material is suitable for installation in the exterior area near the windscreen. The nut works together with washers and seals that protect the wiper shaft from water and dirt during operation. Proper tightening supports consistent wiper movement and position.
