Customer Reviews (4.4 / 5 · 5 reviews)

Benjamin ★★★★★

Packed 5,000 of these #6 lock washers in a single bag — exactly what I needed for high-volume assembly. The 410 stainless with black oxide gives them a solid grip under vibration, and they seat flush every time without binding.

Richard ★★★★★

Installed a hundred of these today for a customer’s vibration-prone assembly, and every one seated perfectly. The black oxide coating seems to offer extra grip during installation. Exactly what I needed for the job.

Julian ★★★★★

Bought these for a small vibration-prone assembly job and the black oxide finish looks sharp out of the bag. The internal teeth grip the bolt head firmly, way better than plain external washers I've used. For a 5000-pack, the price is unbeatable.
