SutemriborM3 M4 M5 Alloy Steel Socket Cap Screws Hex Head Bolt Nuts Assortment Kit M3 M4 M5 Black STBR-560p-M3-M4-M5-heise-hejingangluosi

Used these to mount a scopes. Perfect product for that.

Good quality, packed well and bolts had a nice anti rust coating on them

They do the job very well, especially for the price

Some time ago, I downloaded some .STL files off Thingiverse. I can't recall what the files were for, but the creator specified using M3 screws to assemble the objects components after 3D printing them. I wound up not attempting to print the objects so this kit sat on a shelf.Since then, I've been designing, prototyping, and assembling my own 3D printed components and apparatuses, and this kit has been supplying the screws and nuts for much of said components and apparatuses when they need hardware. Some examples include filament spool rollers, a light fixture for my roll away work station, and even some 3D printed guitar speaker cabinets. This kit is small enough to carry around yet for the most part has supplied the quantities I need.Elaborating on that "for the most part...", I'd like to see a higher quantity of M5 screws and nuts in this kit. I've nearly run out of them but still have a lot of M3 and M4 screws and nuts. I suggest simply increasing the spaces allotted for the M5 screws and nuts to allow more of them to be added to this kit. I wouldn't mind at all if the plastic box was a tad bigger if it had more M5 screws and nuts in it.Overall, this little kit is great for tinkering/hobby engineering. It's not a giant box that'll take up space, but at least in terms of metric fasteners, has the common sizes used in small projects and with the exception of the M5 screws and nuts, has enough of them for a project or a few, depending on need.

Sorry these were fine I wrote on wrong item. These were exactly as promise just wrong style to buy for bike but I would rebuy!!
