حلقات قفل ذات سن داخلي M3 | فولاذ مقاوم للصدأ 18-8 (2000 / عبوة)

Vibration has been a constant headache on my CNC enclosure until I swapped in these 18-8 stainless washers. The 2000-count box feels like a lifetime supply, and they sit snug under M3 screws without any give.

I needed a bulk pack of M3 washers for an electronics project and these 18-8 stainless steel ones feel solid—the internal teeth grip nicely into the fastener. No issues with corrosion or slipping so far, and at 2000 pieces per package it’s a great value for frequent builds.

The internal teeth really dig into the screw head and the stainless steel feels solid. I used them on a small CNC project and haven't had any loosening issues despite the constant vibration.
