I only needed a 5x8mm for my license plate frame but buying one or two pieces was a few dollars...so I bought a set. It's nice that the set comes with regular washers and lock washers. It sucks if you need a washer with a stainless screw but you don't have a stainless washer, that is ultimately why I selected this set. I won't know what grade of stainless for a few months or years and being in CA I will never know the impact of road salt or extreme weather. Overall the set is nicely packaged and they appear to be machined well.

I do a lot of 3d printing projects and a few needed metric fasteners, plus I bought these to go with a multi pack of T nuts for mods to my printers and many other projects.

I like the smaller top screws and bolts nuts. They come in real handy around my house and it was perfect for what I needed it for. They made a very good material. I highly recommend them.

excellent selection in the small hardware category

Great value for the money and everything was organized very well so it was easy to get the right sizes.

The varied thread lengths allow for one-off installations required by the bike owner. High quality bolts. Varied flat washer diameters would be nice a nice addition to the kit. This was the solution for adapting a fork-mount cage to a rear rack application that was not offered by the bike manufacturer.I’m happy.

Used this too assemble me motorized bicycle 🚴
