TOYOTA 90119-08974 Battery Hold-Down Bolt with Washer

The Toyota 90119-08974 is an OEM-quality hex head fastening bolt with an integrated washer (SEMS bolt), primarily designed for securely mounting the battery hold-down clamp and other structural components. This genuine OEM part guarantees a perfect fit and maximum reliability.

Technical Characteristics and Specifications:

• Type: Hex head bolt with integrated washer (SEMS bolt)
• Application: Battery hold-down brackets, mounting elements, and other body fastening points
• Material: High-tensile hardened steel
• Surface Treatment: Corrosion-resistant zinc-plated coating, resistant to engine bay moisture and battery acid vapors
• Manufacturer: Toyota (Genuine OEM part)

Function and Importance:

The battery hold-down bolt is essential for the safe operation of the vehicle. It prevents battery movement and vibration while driving, protecting the internal cells from physical damage and eliminating short-circuit hazards. The integrated washer ensures uniform clamping force distribution, prevents deformation of the mounting bracket, and minimizes the risk of loosening caused by vibration.

Signs of Wear and Failure:

• Severe corrosion or rust: Acid vapors and moisture around the battery can degrade the bolt surface over time, resulting in structural weakening.
• Damaged threads: Cross-threading or tightening with improper torque can strip the threads.
• Rounded bolt head: Using incorrect tools can round off the hex head, making subsequent loosening difficult or impossible.
