DYWISHKEY 1220 PCS M2 M3 M4 M5, 12.9 Grade Alloy Steel Hex Socket Head Cap Bolts Screws Nuts Washers Assortment Kit with Hex Wrenches

These work fine for me, it is a good assortment and the quality is just fine for my use: light electronic prototype assembly. The hex keys worked OK, were a little loose but otherwise just fine.The supplier must have been listening to the problems folks were having with shipping because my shipment arrived with all the screws, nuts and washers in their correct bins. The bins are not removable (one piece), and they put a small piece of bubble pack on the inside of the plastic tray under the lid to capture any loose items. The plastic tray was then wrapped in bubble wrap and shipped in a form-fitting box.I will be buying more of these kits - good job DYWISHKEY. Thank you.

Good quality great variety of screws, nuts, and washers for the hobbyist. Give your projects a beautiful sturdy look with this small set.

Great bolts, washers, and nuts for my 3D printing projects. The base itself is thin and cracked, but the contents themselves are great. Plan on having your own organizer and this will work out just fine.

These are excellent quality. Exact dimensions on the threads and heads. I have never stripped a single one of them. I tighten them down pretty hard too. They are very strong. Shame they don't come with lock washers though. Or have an option to have socket heads or countersink heads. The nuts can vibrate off easily if you don't have lock washers or lock nuts for your project no matter how tight you make them.

I had read that some peoples shipment came with the contents scattered between dividers. Mine came wrapped up tightly in it's own shipping box. The actual container was then wrapped in plastic wrap, and the individual nuts, bolts, washers were in their own plastic bag! Very nice! Nothing messed up.One thing though... the allen wrenches were in a separate bag outside of the nuts/bolts container, so... don't lose those when opening the shipment.These are a great value for the amount you get, and they've worked perfect for my project.

I do quite a bit of 3D printing which calls for small metric bolts and fasteners. I picked this set up and have used quite a bit from it in the past few months. The quality seems very good. When I received the box ALL of the bolts, nuts, and washers were mixed up into different bins. This is a pain. packaging could have been better.

It is what it is. would buy again.I also bought some inserts for these. Depending what i'm doing. I don't always use the inserts. I just screw the screw into my 3D prints. I'm not sure if the inserts are stronger. I have not done a strength test but they do hold pretty well, I can't pull them out with my fingers. I might even consider not get any more inserts.Your printer may vary but here is what I found that has been working for me on my Ender 5.5M - 4.25mm hole4M - 3.5mm hole3M - 2.75mm hole2M - I recommend using an insert. The threads are very small.

Nuts, bolts, and washers seem to be of acceptable quality stainless steel material, but the plastic case included was very thin and flimsy. All of the parts were homogenized (i.e. completely mixed up), and, after about 45 minutes of sorting, I found out that I had only received 3 of the M3x16mm bolts, for some reason, as opposed to the 30 pieces advertised. I didn't count the other pieces, but they seemed to be more or less all there.I still had the envelope (yes, that's right, this didn't ship in a box), so I double checked to make sure I didn't somehow inexplicably miss 27 screws rattling around - but there was nothing in there. Oh well.

Very Nice. Arrived with everything individually wrapped and had a bonus set of allen keys I was not expecting.Even given the situation with COVID (reduced air freight to Australia) the delivery was well within expected timeframes

yep very good item great service amazon ...all arrived ok no damage
