Frog Racing Shows How Vibrations Loosen Car Nuts

Frog Racing released a two-minute YouTube video explaining how vibrations cause car hardware to loosen. The video details how vibration leads to nut and bolt loosening, especially in high-stress conditions like hill climbs. It recommends using wedge-locking washers with cam edges and serrated exteriors to prevent loosening. These washers create a wedge effect through a cam surface with a higher pitch than bolt threads. The video advises checking torque paint to detect loosening early.
