TOYOTA 94184-61001 Lock Nut

This genuine Toyota lock nut (part number: 94184-61001, replacement/alternative part number: 90179-10151) is a premium-quality, heavy-duty fastener specifically engineered for critical vehicle applications. The self-locking design prevents the bolted joint from loosening under vibration or dynamic loads, ensuring secure fastening across the suspension, steering, or other structural assemblies.

Technical Features and Benefits:

• Genuine OEM Quality: Perfect fitment and material quality manufactured to original factory specifications.
• Alternative Part Number: 90179-10151
• Material Composition: High-strength, heat-treated steel capable of withstanding heavy mechanical stress.
• Surface Treatment: Specialized anti-corrosion coating against environmental factors and rust.
• Safety Function: Specialized thread geometry that provides added friction on the bolt shank to prevent unintentional backing off.

Why Is Replacing the Lock Nut Critical?

Lock nuts are safety-critical components. Due to the nature of their locking mechanism, these fasteners are single-use only. Once removed, the locking feature loses its effectiveness, meaning reinstallation cannot guarantee secure retention.

Signs of Wear or Damage:

• Damaged, stretched, or stripped threads observed during disassembly.
• Severe corrosion or rust that compromises the structural integrity of the material.
• Vibration, rattling, or noticeable play in the fastened components.
