The genuine OEM Toyota 90119-06A13 bolt with washer is a premium-quality fastener specifically engineered for the stable and secure mounting of vehicle body components, particularly bumpers, fender liners, and lower engine splash shields.

Technical Specifications and Design

• Type: Hex head bolt with an integrated, free-spinning washer (SEMS design).
• Material: High-strength, hardened steel alloy.

Function and Importance

The integrated washer plays a critical role in the fastening assembly. It evenly distributes tightening torque across the mounting surface, protecting fragile plastic bumper tabs and trims from cracking or deforming. Additionally, it helps prevent the fastener from backing out due to continuous vehicle vibrations.

Signs of Wear or Damage

• Surface Rust or Corrosion: Makes removal difficult and weakens the structural integrity of the bolt.
• Damaged Threads: Frequently the result of overtightening or cross-threading.
• Deformed Bolt Head: Stripped hex head caused by improper tool use, complicating removal and installation.
• Missing Fastener: Bolts lost due to vibration or previous improper repairs can lead to bumper rattling, sagging, or fluttering at highway speeds.
