The specification denotes the dimensions of the fastener used to secure a Camry’s wheel to its hub. This measurement is crucial for proper fitment and safe vehicle operation. For instance, a 2015 Toyota Camry typically requires a specific lug nut dimension, different from other vehicles or even some model years of the same make.
Correct fastener specification is critical to ensure adequate clamping force between the wheel and the hub, preventing wheel detachment. Using an incorrect specification could result in wheel damage, vibration, or, in severe cases, wheel separation, leading to accidents. Historical automotive engineering practices emphasize the precise matching of fasteners to vehicle components to ensure optimal safety and performance.
