TOYOTA 90159-60416 Bumper Screw with Washer

The Toyota 90159-60416 is a genuine OEM retaining screw with an integrated washer, primarily designed for the secure and vibration-free mounting of bumpers, fender liners, engine undercovers, and other body panels.

Technical Features and Benefits:

• Integrated Washer Design: The built-in captive washer evenly distributes clamping force across the mounting surface, protecting delicate plastic body components from cracking and deformation.
• Superior Corrosion Protection: Manufactured from specially surface-treated steel to resist moisture, road grime, and winter road salts.
• Combination Drive Head: Features a combined hex and Phillips recess head design, enabling quick and slip-free installation with either hand or power tools.
• Vibration Resistance: Precision thread manufacturing prevents the screw from backing out under continuous vehicle operating vibrations.

When Should It Be Replaced?

Fastener replacement is recommended if threads are stripped from overtightening, the screw head is rounded or damaged, or surface corrosion has compromised fastening security. During the removal and reinstallation of exterior panels, damaged or missing screws should always be replaced with genuine factory parts to ensure a precise fit and rattle-free assembly.
