  • Perfect
Color: Silver Size: M2 M3 M4 M5
Exactly as described. This set of metric 304 SS button head screws, nuts and washers is outstanding. For those working with electronics, 3D printers etc, the smaller sizes are the most commonly needed, especially M3 and M4, at least in my experience. This kit focuses on that size range including a large number of M2, M3, M4 and M5 screws each in four lengths from 8 mm to 20 mm. M2 are less common and it is nice to have them included. Washers and nuts for each size are included, as are hex wrenches in all 4 sizes and a pair of tweezers. The screws and nuts are smoothly threaded and each piece I tried fit flawlessly. Beyond the hardware itself, the case is excellent. It is the usual thin plastic but it addresses every issue I have had with these boxes. First, the catches work smoothly and lock well. The compartments are small so the tweezers can help, but there is a separate compartment for every screw, nut and washer size, something that might seem obvious but that I have found not to be the case in the past. Even better, the separators are fixed in place, not removable, so they don’t come loose at the bottom, and they extend all the way to the top. As a result, the usual mixing of contents and jamming with nuts and screws stuck under loose partitions does not occur. Perhaps a small matter, but this is the way all small parts cases should be made. The compartments are labeled on both the outside and inside the lid of the box so finding the right part is quick. This may be the best metric screw set I have seen and well worth the price. Highly recommended. ... show more

  • Nice selection of M4 bolts, washers, and nuts.
Color: Silver Size: M4
The nuts and bolts thread on smoothly and the machining feels clean with no rough edges. A really nice selection of 8mm to 30mm in length bolts. The set includes a tiny hex wrench, which I doubt I'll be using, but it's included nonetheless. I did notice there is some variation in color on some of the items. Most are a shiny silver stainless color, but the 25mm and the lock washers have more of a black tone to the silver. This is something to keep in mind if your application requires consistent color. For me, it does not matter, as I ordered them for 3D-printed part assemblies, and I rarely use multiple sizes on one part. But the fact that there are 110 bolts and 110 of each type of washer but only 50 nuts will be an issue I'll need to address. I'll be ordering at least 60 more M4 nuts to make these work for me at some point. This is clearly stated in the description, however, and I did know that before ordering. It's just odd not to sell the set without even numbers of the components. The case and especially the latch are pretty flimsy, and I suspect I'll be keeping a rubber band wrapped around the case as I've experienced the joy of picking up and sorting several hundred spilled nuts, washers, and bolts before, and I definitely do not wish to do it again. That being said, I am still quite happy with the product as it's still a ton of high-quality fasteners at a very affordable price. ... show more

  • Great to have around
Color: Silver Size: M2 M3 M4 M5
I do a lot of custom work on my vehicles and this hardware set and come in handy more times than I can count. I personally love button head hardware, they just look clean and these are no exception. The threads are cut well, no issues so far. Contains many of the of the most commonly used automotive sizes. ... show more

  • All the sizes of machine screws every home owner ever need
Color: Silver Size: M2 M3 M4 M5
This MYWISH screw kit covers most of the typical machine screw sizes you'll likely encounter for equipment repairs and DIY projects around the house. With 1290 pieces in M2, M3, M4, and M5 sizes, you should find what you need. The plastic organizer is also a plus for keeping everything sorted. While these aren't the cheapest screws on the market, they offer decent enough quality for general-purpose use. They might not hold up under extreme stress, but for most simple tasks, this kit is a convenient solution. Overall, this kit is a solid option for homeowners who need a variety of screws at hand. If you frequently tackle heavy-duty projects, you might want a more robust set with higher-quality components, but for most simple tasks, this will get the job done. ... show more

  • Perfect for high-moisture environments
Color: Silver Size: M5
These are perfect for high-moisture environments. I have had the worst time trying to remove rusted screws that either strip out or break due to rust so now I will only use stainless screws for anything that is exposed to moisture and the outdoors. These are a bit pricy compared to regular carbon steel screws but they are absolutely worth the price for me any day as I never have to waste my time trying to remove rusted frozen screws that either strip out or break. The time I save not having to drill out and retap screws is worth the slight increase in price for me. Not only that, these fit great and look amazing over time as they don't become rusted over time. ... show more

  • Convenient assortment
Color: Silver Size: M2 M3 M4 M5
First ... just to correct the headline in the listing ... these are NOT screws. They are bolts. There is a difference. Now for the review: If you are like me, you are forever digging through your junk drawers looking for a small screw or bolt to fit some appliance or computer that has lost one (usually found years later hiding under a sofa cushion or in a crevice between the wall and carpet). This is a great little assortment for just that sort of emergency. It has a wide range of sizes--all small--along with washers and nuts to fit each size, if needed. They seem to be well made and are bright and shiny (no rust). They are housed in a neat little container (so you can tuck the whole thing in your drawer instead of digging around for loose bolts) and even come with a little pair of tweezers to help you pick out just one without having to dump the whole thing out. One word of warning, in case you aren't into hex head bolts--these are HEX HEAD BOLTS. However, they also come with assorted hex wrenches to fasten them with, so you're covered. Overall, this is a nice little assortment for a not too unreasonable price--especially considering that buying these separately is nearly impossible and you probably don't need a box full of each size. ... show more

  • Only has half the nuts
Color: Silver Size: M4
Good assortment of M4 screw lengths with nuts, washers, and lock washers. It has 110 total screws, and the same number of washers and lock washers, but only 50 nuts. Overall, a good set to have for 3D printer enthusiasts.
