TOYOTA 91631-B0616 Bolt with Washer

This genuine Toyota (part number: 91631-B0616) bolt with washer is a premium quality, factory OEM fastener. Genuine parts guarantee a perfect fit, maximum reliability, and long service life, meeting Toyota's strict quality control standards.

Technical Features and Benefits:

• Integrated washer: The design with a washer ensures even clamping force distribution across the fastening surface, reducing the risk of surface damage and preventing vibration-induced loosening.
• Superior material quality: Manufactured from high-tensile steel capable of withstanding mechanical stress and shear forces.
• Corrosion protection: Features a specialized surface coating that provides effective protection against rust caused by moisture, dirt, and road salt.
• Factory specification: Precise thread pitch and dimensional tolerances for secure, stable fastening.

Application and Importance:

In vehicles, bolts and fasteners play a critical role in securely mounting various sub-assemblies (engine components, body parts, brackets, or electrical units). Using subpar or damaged bolts can lead to loosening of fastened components, rattling, or even severe mechanical failure.

Typical Signs of Wear or Damage:

• Thread elongation or damage resulting from overtightening.
• Visible corrosion or rust on the bolt head and threads.
• Bolt head deformation (rounding) caused by using incorrect tools.
• Vibration or instability of the fastened component.

For safe operation, it is recommended to immediately replace damaged or corroded fasteners with genuine new Toyota parts.
