غسالات قفل ذات أسنان داخلية M5 | فولاذ مقاوم للصدأ 18-8 (2000 / عبوة)

Bought these for a vibration-prone assembly on my motorcycle, and the 18-8 stainless steel gives me confidence they won't rust. The internal tooth design grips the bolt head firmly, and at 2000 pieces per package, I have plenty for future projects.

I needed a bulk pack of M5 lock washers for a vibration-prone assembly, and these 18-8 stainless ones fit perfectly without any burrs. The 2000-count box is more than enough to get through the whole project.

Got these for a batch of M5 bolts on a project that sees a lot of vibration. The 18-8 stainless steel feels solid and they lock tight without damaging the threads.
