NISSAN 16551-W700A Wing Nut

The genuine NISSAN part number 16551-W700A wing nut is designed for the reliable, tool-free fastening of various engine compartment assemblies—most commonly the air cleaner housing or other components requiring quick servicing. The winged design allows for fast, accurate hand tightening, facilitating routine maintenance, inspection, or filter element replacement without the need for hand tools.

Technical Features and Role

The wing nut is manufactured from durable metal with a corrosion-resistant surface finish, engineered to withstand high temperature fluctuations, mechanical vibrations, and automotive fluids within the engine bay. The precision-machined internal thread ensures secure retention, preventing fastened components from loosening despite engine operating vibrations.

• Part Type: Wing nut (NUT-WING)
• Manufacturer: NISSAN
• OEM Part Number: 16551-W700A
• Superseded / Alternative Part Number: 16551W7000
• Fastening: Hand-tightened winged profile, standard metric internal thread

Signs of Wear and Failure

Damage to the wing nut typically results from thread stripping due to overtightening, mechanical deformation of the wings, or corrosion following wear of the protective coating. An improperly tightened or missing wing nut can cause loose mounting, leading to rattling noises or, in the event of compromised sealing, allowing unfiltered air to bypass into the engine.
