Customer Reviews (4.6 / 5 · 5 reviews)

Henry ★★★★★

Finally found a pack of #1 lock washers that actually fit the tiny bolts I was working with. The stainless steel feels solid, and they held tight even after a few hours of vibration from my small engine project.

Sofia Q. ★★★★★

Was a bit skeptical about stainless washers holding up under constant vibration, but these #1 split lock washers haven't budged on my lawn equipment after several weeks. The 18-8 material feels solid and corrosion-free. Exactly what I needed for the price.

Miles ★★★★★

Used these on a small electronics project where vibration was a concern, and the 18-8 stainless steel held up perfectly without any corrosion. They fit the #1 screws exactly right, and the split design locked everything in place.
