Steven O. ★★★★★

I needed a bulk pack of lock washers for a project with lots of vibration, and the black oxide finish on these resists corrosion nicely. The external teeth grip the fastener head firmly, which gives me peace of mind on the assembly line.

Penelope N. ★★★★★

The black oxide finish on these washers is holding up nicely without any rust after a week in a damp shop. Each pack has exactly 2,000 pieces, saving me from buying small bags repeatedly.

Jacob ★★★★★

I needed a bulk pack of lock washers for a project and these fit the bill perfectly—the teeth really grip tight when torqued down. The black oxide coating held up well against some minor moisture exposure during assembly.
