NISSAN 73898-1AA0A Torx Roof Bolt

The Nissan 73898-1AA0A genuine (OEM) Torx roof bolt is a premium-quality, precision fastener designed for the secure and vibration-resistant mounting of the vehicle's roof structure, roof rails, or other body components. The use of genuine Nissan parts guarantees a perfect fit, tensile strength meeting factory specifications, and long-term reliability.

Technical Features and Specifications:

• Manufacturer: NISSAN (Genuine OEM part)
• Part Number: 73898-1AA0A
• Part Name: Roof bolt, torx
• Drive Type: Torx (internal drive), which provides maximum torque transfer during assembly, preventing tool slippage and fastener head damage.
• Material Quality: High-strength, hardened steel alloy engineered to withstand mechanical stress and vibration.
• Surface Treatment: Specialized anti-corrosion coating that provides protection against moisture and environmental exposure.

Function and Importance:

Roof bolts play a critical role in the stable attachment of exterior body components and accessories (such as roof rails, trim moldings, or roof rack mounting points). The Torx profile allows the application of precise tightening torque in accordance with factory specifications, which is essential for secure fastening and maintaining watertight sealing.

Typical Signs of Failure or Wear:

• Thread damage or thread stretching: Frequently the result of overtightening (excessive torque).
• Damaged Torx drive profile: Internal socket wear caused by using incorrect tools or improper installation, making safe tightening or removal impossible.
• Corrosion: Rust appearing after damage to the protective coating, compromising the structural integrity of the bolt.
• Moisture leaks: If the bolt loosens or fails, water can seep past the mounting point into the passenger cabin.
