The wiper arm assembly cup nut is a small but essential fastening component that protects the threaded spindle and ensures the wiper arm remains firmly attached during operation. Over time, the original cup nut can become corroded, rounded, damaged, or lost during servicing, affecting both the appearance and security of the wiper assembly. This OE Match replacement restores proper fitment and factory-style detailing, making it ideal for routine maintenance, repairs, and Porsche restoration projects.  

What This Product Does:

• Secures the wiper arm to the wiper spindle.
• Protects the threaded spindle from dirt and moisture.
• Maintains the correct clamping force on the wiper arm.
• Restores the original factory-style silver appearance.
• Replaces worn, damaged, or missing original cup nuts.
• Helps ensure reliable wiper arm operation.
• Provides an OE-style fit and durable finish.

Symptoms Of Wear Or Failure:

• Corroded or rusted cup nut.
• Rounded or damaged hex surfaces.
• Loose wiper arm fitment.
• Missing cup nut.
• Difficulty tightening the wiper arm securely.
• Cosmetic deterioration of the silver finish.
• Damage caused during previous servicing.
• Age-related deterioration of the original fastener.

Why Replacement Matters:

• The wiper arm assembly cup nut is a vital fastening component that keeps the wiper arm securely attached to the spindle while protecting the threaded end from corrosion and contamination. A worn, damaged, or missing cup nut can result in a loose wiper arm, reduced wiping performance, and an unfinished appearance.
• Replacing the original cup nut restores secure wiper arm retention, protects the spindle threads, and maintains the factory-style finish of your Porsche's wiper assembly. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match silver cup nut provides the correct fit, dependable performance, and long-lasting durability, making it an excellent choice for maintenance, repairs, and restoration projects.
