Lucy ★★★★★

The 316 stainless is the real deal—I can tell just by the weight and finish that these won’t pit or discolor like cheaper zinc ones. They’re a solid .053” thick, so they sit flat and distribute pressure evenly under bolts without bending. Exactly what I needed for a salt-air environment.

Claire ★★★★★

I needed washers that wouldn't rust in a marine environment, and these 316 stainless ones are exactly what I was looking for. The .053" thickness gives them a solid feel under the bolt head.

Sebastian N. ★★★★★

Installed these on my dock hardware and the 316 stainless is holding up perfectly against the salt spray. The 0.053 inch thickness feels solid and distributes the load evenly under each bolt.
