Julian ★★★★★

I've been using these #5 lock washers for a few projects that see a lot of vibration, and they haven't loosened at all. The 18-8 stainless steel feels solid and corrosion-resistant, which is exactly what I needed for outdoor gear. Definitely a solid buy for the quantity.

Sebastian C. ★★★★★

These came in a massive bag, and I like the split design that actually locks the bolt. Perfect for my vibration-prone lawn mower deck, and the 18-8 stainless has held up without any rust so far.

Christopher ★★★★★

The 18-8 stainless steel feels solid, and these #5 washers fit perfectly on my small machinery assembly. No corrosion worries since I used them outdoors in damp conditions.
