LC LICTOPM4 Stainless Steel Round Flat Washer for Bolt Screw, Metal Gaskets, 12mm/0.47'' Outside Diameter, 100Pcs

More in the package than I am likely to ever need but the price was reasonable and the washer has already been useful on a couple of projects. Worked great to tighten the fit when replacing cabinet handles where the supplied screws were just a fraction too long. No problems with the product quality. It is a basic washer and does what it is made for.

I needed these to help mount a VESA monitor which uses M4 screws. Worked great.

These washers were the perfect thickness and size for what I needed them for, and so far I haven't noticed any irregularities in outside diameter, inside diameter, or thickness. Speaking of the thickness, make sure you look at the dimensions and see if they're right for your application. There are super thick all the way down to paper-thin washers, so be sure you're getting the right one for your needs.

Ordered these for a particular application that needed a thin washer and the description stated these where 0.02" thick. As received the washers measured 0.04" thick or double the stated thickness.Unfortunately, these will not work for me, but it's not worth the hassle to return them.

Not one to leave feedback, but the hardware I've been receiving here at Amazon has been for the most part imported garbage! I'm not a radical nut job complaining about China and other countries, but this stuff sucks! As stated, the washers are paper thin, the screws and nuts and bolts are poorly machined and or cast. It's become a total crap shoot and a waste of time and money purchasing hardware here on Amazon. Too bad as it could and should have been good thing for all involved. As far as hardware, I'm done!

I ordered these as they are supposed to be 0.5mm thick. Instead they are 1mm.

These washers worked like expected, then fit over the bolt between the mounting surface and the nut.
