حلقات قفل انقسام متوسطة M3 | فولاذ مقاوم للصدأ 18-8 (200 / عبوة)

Exactly what I needed for securing some electronics enclosures against vibration. The 18-8 stainless steel feels solid and corrosion-resistant, and the 200-count pack will last me through many projects.

Finally found split lock washers that don't rust on my marine electronics project, and these 18-8 stainless ones hold up perfectly even in salt air. The M3 size fits snugly on standard metric bolts, and the split design really digs in when torqued down.

Installed these on a few 3D printer builds where vibration was an issue, and they’ve held everything tight without any loosening. The 18-8 stainless steel feels solid and corrosion-resistant. Exactly what I needed for a reliable mechanical fix.
