An automotive eccentric bolt is a fastener whose central axis is not concentric with the head centre (possessing an eccentric offset). Its design feature involves an eccentric distance between the bolt shaft and the head. When the bolt is rotated, the eccentric portion generates mechanical advantage, making tightening or loosening the bolt less strenuous.

Automotive eccentric bolts are extensively employed in vehicle chassis and suspension systems, primarily for wheel alignment adjustments. Typical applications include:

• Camber adjustment: Installing eccentric bolts modifies the wheel's inclination relative to the vertical plane, optimising tyre contact and traction.
• Toe adjustment: Eccentric bolts also enable precise fine-tuning of wheel toe angles (i.e., the parallelism between left and right wheels), ensuring correct wheel alignment during straight-line driving.
• Suspension component positioning: Beyond wheel angle adjustment, eccentric bolts allow slight rearward or forward movement of suspension components such as steering arms and tie rods.
