TOYOTA 94185-61000 Lock Nut

The genuine TOYOTA 94185-61000 lock nut is a premium-grade, high-strength fastening component specifically designed for use in critical vehicle assemblies subjected to high vibration and dynamic loads. The self-locking mechanism prevents spontaneous loosening of the bolted joint, ensuring the safe and stable fastening of suspension, steering, or other structural components.

Technical Specifications and Product Features:

• Manufacturer: TOYOTA (Genuine OEM Part)
• Part Number: 94185-61000
• Part Description: Lock Nut
• Material Quality: High tensile strength, hardened alloy steel engineered to withstand maximum shear and tensile loads.
• Surface Treatment: Specialized anti-corrosion coating resistant to moisture, road salt, and environmental elements.
• Locking Technology: Precision-engineered self-locking thread profile or prevailing torque deformation zone, ensuring constant clamping force without the need for additional lock washers.

Function and Importance of the Lock Nut:

During vehicle operation, the suspension and drivetrain are continuously exposed to vibrations. Standard nuts may back off over time under constant vibration, leading to severe safety hazards or component failure. Through its internal locking design, the lock nut creates supplementary thread friction, thereby preventing unintended rotation.

Maintenance and Replacement Information:

• Single-Use Fastener: In accordance with factory service procedures, most prevailing torque lock nuts are single-use components. Once removed, their locking capability is compromised; therefore, a new genuine nut must always be installed during reassembly.
• Tightening Torque: Strictly adhere to the factory tightening torque specified by TOYOTA during installation to prevent thread damage.
• Signs of Wear: The fastener must be replaced immediately in the event of thread damage, visible corrosion, play in the secured assembly, or deformation from prior installation.
