This set of screws arrives in a suitably sized clamshell plastic box with the opening side sealed with a clear sticker, which did the job flawlessly. The front of the packaging has a DTGN branded sticker placed onto it and that contains all the information you’d need to know about the screws alongside an image of the screw itself.I did a quick check with my scales to count the contents of the box and I received and found that there were only 99 screws in the package, which is quite disappointing. I manually counted after checking with the scales to make sure it wasn’t an error or weight discrepancy but I counted the same number. All the screws are uniform in quality and I haven’t spotted any screws in the box with malformed threads, heads or sockets and they’ve got no issues with my 2.5mm Allen Key, M4 tapped holes and M4 hex nuts. They do measure a smidge short when excluding the head and after measuring a handful of them they’re consistently around 17.95mm from the head to the tip, which is close enough for me personally speaking and is within ISO 7380:1 standards.They’re very mildly magnetic which does line up with the claim of them being 304 stainless steel, which becomes slightly magnetic when it’s cold worked/formed. Though I'm not entirely sure why they’re mentioning that the screws are ‘whitewashed’ as they’re just the typical bright silver you’d see on any A2 fastener.At the time of writing they’re charging £6.99 for a pack of 100 screws, which is very competitive for A2 M4 by 18mm button heads and they’re significantly cheaper than my usual sources of fasteners, which isn’t very common for small quantities, especially on Amazon. The only reason I haven’t given this the full five stars is because my set arrived short one screw, but otherwise this brand is a great source of reasonably priced fasteners on Amazon.

I needed these M4x40mm screws for installing some mud guards on my Surron. I have Topeak defender XC1 mudguards which I've been using for several years now. I recently had my forks services but I could not remove the fender since the bolts had corroded too much and just stripped out. So I ended up cutting the bolts and installing these in their place. These bolts fit great in the barrel nuts on the other end of the fender and work with standard M4 threads. As far as I can tell, these are pretty typical button head screws.The packaging that these came in could have been better but its far from the worst I've seen. At least all the screws were still in the box they shipped in. It probably would have been nice if the seller put the screws in a plastic bag instead of loose in a box but its not a big deal since you only get one type of screw so you don't need to sort anything after receiving them.Overall, I'm quite happy with these screws. They have a nice stainless steel finish and work great with standard M4 threads. They are sufficiently long for my project and are very standard button head screws. The price is also quite reasonable compared to similar screw listings on Amazon. 10/10 highly recommend these if you need this particular size of screw.

I need M5's all the time. These are excellent quality; precise and nicely finished.

I ordered M4-0.7x16mm. That’s exactly what I got.I needed spare screws for a knife sharpener. The quality of the screws is the same as the ones they are replacing. The fit is exact. They even look the same.The price for 50 screws for $10 might be a tad high, but the quality is good, and you get it delivered to your door.5 Stars

I ordered a 30-pack of these coarse-thread (0.7 mm pitch) M4 x 22 mm stainless-steel screws and couldn't be happier with them. As one would expect, their thread size and length are correct, their hex sockets are typical, and their finish is good.The product description describes their finish as "whitewashed", which isn't quite how I would describe it. In my experience, stainless screw finishes can be bright (uncoated), a slightly matte silver (like these ones), or black (oxide coating).Mechanically, these screws seem perfect to me and their slightly matte finish is consistent and attractive. At their current price of C$9.99 for a 30-pack (C$0.33/screw), I consider them to be a good value.

These screws have a very regular thread with no burring or other residue. They are done in 304 stainless steel for excellent corrosion resistance and they are non ferromagnetic.The hex drive works well with an Allen wrench and it's easy to get good torque. There's no slipping or rounding of the drive with a properly sized hex bit.These are the metric M4 size with a relatively coarse thread. They are an excellent choice for any situation where they are exposed to the elements such as a trailer or bicycle.

It would be difficult to find ways to deduct stars from this product. It either is what it says it is or it's not. There is not specified information about what kind of weight it is capable of bearing or any other information for me to refute.The screws have button heads and I utilized them to hold a monitor that I needed a large that I 3D printed to make it so it aligned with my lower monitor. They did that without excessively flexing. When I screwed/unscrewed them there was no damage to the heads to make me think they aren't durable and capable of being used and reused.

These M4 screws are in-spec, which is the best you can say about commodity hardware. It's a decent price as of now, which I hope holds in the future. I get a lot of my hardware from here rather than a brick and mortar store, and I have rarely been let down.
