OEM Lock Nuts M4 20 Pieces

OEM Lock Nuts M4 – Secure Fastening for Modelling

The OEM lock nuts M4 are self-locking nuts specifically for M4 threads. They reliably prevent screws from loosening, even under strong vibrations.

• The M4 lock nuts stay tight despite vibrations, ensuring long-lasting stability of your models.
• The set of 20 pieces covers multiple projects or serves as a handy workshop refill.
• Thanks to the self-locking property, maintenance is reduced – no need for constant retightening.
• The nuts fit standard M4 screws and are versatile in the RC field.

What makes the lock nuts M4 special

Lock nuts differ from standard nuts by their special geometry or an integrated plastic ring that prevents loosening. Even in vibration-heavy RC environments, they maintain reliable grip and increase operational safety.

Ideal for...

Ideal for RC modellers who want to equip their vehicles, aircraft or helicopters with reliable fastenings. Also recommended in other vibration-prone applications such as mechanical engineering or automotive.

How to use the lock nuts M4

Screw the nut by hand onto the M4 thread, then tighten with a suitable wrench (usually 7 mm hex). The locking feature engages automatically and prevents loosening – no glue required. The nuts can be reused as long as the locking property remains effective.
