TOYOTA 91651-B0822 Bolt with Washer

The genuine OEM Toyota 91651-B0822 bolt with washer (original designation: BOLT, W/WASHER) is a premium quality, high-strength fastener engineered specifically to meet the strict factory specifications of Toyota and Lexus vehicles. The integrated washer ensures even distribution of clamping force, prevents damage to mating surfaces, and reduces the risk of loosening caused by vibration.

Function and Importance

Fasteners used in motor vehicles are continuously exposed to vibration, temperature fluctuations, and environmental influences (moisture, mud, road salt). Genuine Toyota bolts guarantee the correct tensile and yield strength limits, preventing critical components from loosening or breaking. The integrated washer protects the mounting surface from scratching and deformation during assembly.

Signs of Wear or Damage

• Corrosion and Rust: Weakens material structural integrity and makes removal difficult.
• Damaged or Stretched Threads: Threads can deform due to over-torquing or improper installation, leading to fastening failure.
• Deformed Bolt Head: Using improper tools can round off the hex head.
• Loosening: If the bolt loses its clamping tension, it can lead to vibration or detachment of the secured assembly.

To ensure safe and reliable operation, always replace damaged, corroded, or single-use bolts with genuine Toyota parts.
