TOYOTA 90942-01082 Wheel Hub Nut

The genuine TOYOTA (SKU: 90942-01082) wheel hub nut is a critical fastener responsible for securely and stably attaching the vehicle's wheels to the wheel hub. This premium quality genuine OEM part guarantees precise fitment and maximum safety during everyday driving.

Technical Specifications and Features

While the manufacturer database does not include unique custom specifications, the TOYOTA 90942-01082 wheel nut features the following general technical parameters:

• Thread Size: M12 x 1.5
• Seat Type: Mag seat (flat seat with captive washer) specifically designed for factory alloy wheels
• Hex Size (Wrench Size): 21 mm
• Material: High-strength steel alloy with corrosion-resistant chrome plating
• Fitting Position: Front and rear axle (universal)

Role and Importance of the Wheel Nut

The primary function of the wheel nut (NUT, HUB) is to clamp the wheel rim firmly and evenly against the wheel hub. Wheel nuts torqued to manufacturer specifications ensure that the wheel does not loosen during rotation and can withstand the substantial shear and tensile forces encountered during cornering, acceleration, and braking. Using genuine Toyota parts ensures that the thread pitch and contact seating geometry match the factory wheel hub studs and wheel rim mounting holes perfectly.

Common Symptoms of Wear or Failure

Over time, wheel nuts can wear out or deteriorate due to improper tightening torque (over-torquing or under-torquing), environmental exposure, and frequent wheel changes. Common failure signs include:

• Damaged or Stretched Threads: Makes installation and removal difficult, significantly reducing fastening security.
• Corrosion and Rust: Weakens the material structure and can cause the wheel nut to seize or snap.
• Rounded Hex Corners (Head Damage): Caused by using incorrect tools, leading to socket slippage and making wheel removal impossible.
• Washer Deformation or Loss: Compromises proper seating contact, which can cause the wheel to work loose.

To ensure driving safety, immediate replacement of damaged, corroded, or thread-stretched wheel nuts is recommended, along with tightening strictly to factory torque specifications.
