I ordered this collection of washers to keep on my workbench for repairs. It seems I often need a washer for something when I have a repair I am working on. This is a good set. It includes both flat and lock washers. They are stainless steel, so they should be more rust resistant than other washers. I like that the hinged plastic container is clearly labelled and keeps everything organized. Five stars.

This collection of stainless metric spring lock washers appears to be of good quality, organized in a small but functional plastic clamshell case.The case size/design doesn't lend itself to storage of the quantity of M10 and M12 washers in this set - they've overflowed into the M2.5 and M2 compartments (see pic). This is a minor issue; not significant enough to knock a star off of the rating.

I usually check 304 stainless steel fasteners with a magnet to verify they are truly 304 SS since 304 stainless should NOT be magnetic but 410 stainless steel is and is a lower quality stainless steel.From what I understand, 304 stainless steel could turn magnetic under some specific and unusual circumstances in the production but my suspicions are that these are not 304 stainless steel and something of a lesser quality. That aside, these do appear well made.

Was not stainless. Badly failed the magnet test.

This is a pictured, you get a ton of very very tiny washers in this kit. They seem nicely made.
