Nylon Insert Lock Nuts M3×3 (Pack of 10)

Nylon Insert Lock Nuts M3×3 – Pack of 10

Nylon Insert Lock Nuts (Nyloc nuts) are self-locking fasteners that use an integrated nylon collar to grip the bolt thread and resist loosening from vibration — essential for RC aircraft servo mounts, control horns, landing gear, and any lightweight structural fastening subject to engine or flight vibration.

• Thread Size: M3
• Height: 3mm
• 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: Servo mounts, control horns, small motor mounts, landing gear, and structural fastenings on RC aircraft and cars
• Advantage: Reusable, no thread-lock compound required, reliable in high-vibration environments

The M3 size is one of the most commonly used fastener sizes in RC aircraft construction — nyloc nuts keep your hardware tight through every flight without the mess of thread-lock adhesive.
