Customer Reviews (4.4 / 5 · 5 reviews)

Richard ★★★★★

The black oxide coating on these washers looks clean and seems durable. They’re perfect for adding a bit of extra surface area under bolts. Exactly what I needed for a tight assembly job.

Natalie K. ★★★★★

I needed a batch of M12 washers for a custom shelf build, and these are exactly the right thickness to keep the bolt heads from digging into the wood. The black oxide coating gives them a nice, uniform look without any oily residue.

Eli ★★★★☆

Fit well under the bolt head to spread the load evenly, and the black coating seems durable so far. Just what I needed for a handful of small framing repairs.
