Customer Reviews (4.4 / 5 · 5 reviews)

Ellie ★★★★★

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.

Stella T. ★★★★★

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.

Carter Y. ★★★★★

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.
