Nylon Insert Lock Nuts M4×4 (Pack of 10)

Nylon Insert Lock Nuts M4×4 – Pack of 10

Nylon Insert Lock Nuts (also known as Nyloc nuts) are self-locking fasteners that use an integrated nylon collar to grip the bolt thread and resist loosening from vibration — making them an essential choice for RC aircraft motor mounts, landing gear, and any structural fastening point subject to engine or flight vibration.

• Thread Size: M4
• Height: 4mm
• Pack Contents: 10 pieces
• Material: Metal with nylon insert (steel or zinc-plated)
• Locking Mechanism: Nylon collar deforms around bolt thread to resist vibration-induced loosening
• Application: Motor mounts, landing gear, engine bearers, servo mounts, and structural fastenings on RC aircraft and cars
• Advantage: Reusable, no thread-lock compound required, reliable in high-vibration environments

A must-have for any RC builder who wants fasteners that stay tight — nyloc nuts are the professional standard for vibration-prone assemblies and eliminate the need for thread-lock adhesive on most applications.
