Eli ★★★★★

These little washers come as advertised—#1 size, 18-8 stainless, and a full 800 in the bag. I used them on a small vibration-prone bracket and they've held tight through a week of use so far.

Nicholas ★★★★★

I've been using these #1 lock washers on a small electronics project with constant vibration, and they've held everything tight without loosening. The 18-8 stainless steel feels solid and resistant to corrosion, which was exactly what I needed.

Madison L. ★★★★★

Needed #1 lock washers for a tight electrical enclosure, and the 18-8 stainless build feels solid enough to handle vibration. Pack of 800 meant I had extras for future projects, which saved me a trip to the hardware store.
