A belt tensioner bolt clamps the tensioner body to the engine so the spring arm can hold steady pressure on the accessory belt. It also has to keep its clamp load through constant belt vibration. BMW uses this M8x30 bolt on a long run of cars, including the E82 1 Series, E90 through E93 3 Series, F30, F32, and F22 platforms, F10 and F07 5 Series, F01 and F02 7 Series, E70 and F15 X5, E71 and F16 X6, F25 X3, F26 X4, and E89 Z4. It also appears on several BMW motorcycles. Order the exact count you need, because each bolt is priced separately.
