TOYOTA 90119-10536 Body and Chassis Bolt with Washer

The Toyota 90119-10536 is a genuine OEM quality hex head bolt with an integrated washer, specifically engineered for the secure fastening of body and chassis structural components. The integrated washer design (Bolt w/ Washer) ensures optimal distribution of clamping force, protecting mating surfaces from mechanical damage and stress concentration.

Technical Features and Benefits:

• Integrated Washer: Prevents surface damage caused by direct bolt head contact, increases the bearing surface area, and effectively reduces the risk of loosening due to vibration.
• Premium Material Quality: Manufactured from high-tensile steel alloy engineered to withstand significant shear and tensile stresses.
• Corrosion Protection: Features a specialized surface treatment (galvanized or phosphated) that provides long-lasting defense against oxidation caused by moisture, road grime, and de-icing salts.
• Precision Thread Design: Guarantees an exact fit and safe application of factory-specified tightening torque.

Applications and Importance:

This fastener is vital for maintaining the vehicle's structural integrity. It is most commonly utilized for securing suspension components, chassis braces, bumper brackets, fenders, or other body elements where vibration resistance and reliable mounting are essential.

Signs of Wear or Failure:

• Visible Corrosion: Severe rust accumulation on the bolt head or threads that compromises material strength.
• Thread Damage: Stripped or stretched threads resulting from improper tightening torque (over-tightening).
• Deformation: Bending, cracking, or distortion caused by physical impact, collision, or mechanical overload.
• Loosening: Rattling, instability of fastened parts, or abnormal noises coming from the chassis or bodywork.

To ensure safe vehicle operation, damaged, corroded, or deformed bolts should always be replaced with genuine Toyota OEM fasteners, adhering strictly to proper factory torque specifications.
