When screw performance matters, the TOPRAN 109 779 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Thread Size: M 12, Overall Length [mm]: 133 mm, Spanner Size: Synthetic, Bolt Head-/Nut Design: Steel, Surface: Nylon. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 01198, 32 90 1198, 50978, 8501 N90354401 and 6 more. Matching these numbers confirms a like-for-like replacement with no loss of function.
