DYWISHKEY 310 Pieces M2 x 4mm/6mm/8mm/10mm/12mm/16mm/20mm, Stainless Steel 304 Hex Button Head Cap Bolts Screws Nuts Kit with Hex Wrench

good threads in convenient box

Not too much you can say about a box of screws and nuts; other that when you need that size it is hadny to have an assortment handy.

The product was exactly what I had in mind: a quality small fastener with enough variety in lengths to provide a hardware store type selection at the shop. The case that was provided was FAR short of the quality shown in the fasteners, the main culprit being the clasp and latching portion. It actually made you spill the contents once you finally got it to release, due to the huge hand-force needed. The shrink-wrap over the case was another challenge, you basically have to use a sharp knife or scissors to get into the package. This also is hazardous due to the overall flimsiness of the case material. Bottom line: GREAT fasteners, HORRIBLE container.

Great screws, nice quality. If shaken to much some compartment spill over when Iid is closed a minor inconvenience.

The hex size on these is not a standard 1.5mm, 1.5mm is too big. I put my 1.3mm driver in and all seemed well. That is until tension was on the fastener and the head proceeded to strip out. Luckily it was far enough out a simple pair of pliers were able to remove. Then it happened over and over for about 3/10 fasteners of various lengths. So i though well may it is actually a 1.4mm and the included Allen Key would work. Nope the included allen key is 1.3mm as well. It strips out the fasteners even easier then my high quality 1.3mm driver bit. Either the hex is improperly sized on these fasteners, or the metal is so weak the smallest bit of tension strips them out. I am leaning towards the ladder as some fasteners thread in just fine with my 1.3mm Driver. Like i said, around 3/10 fasteners fail.

Excellent quality stainless steel. Assortment includes common sizes. I use these in the assembly of 3d-printed models.

I lost the Hex screws to mount the fans on my hotend to my creality Ender 5 so I figure I could buy replacement screws. The details shows the size I needed but what I was was much smaller than I anticipated I was getting. Even though they are smaller than I need I cannot complain about the quality..... I'm sure I can put them to use eventually. The problem I've actually had was the delivery situation. The driver left the package at my neighbor's and pretty much didn't pay attention to the apartment numbers. Luckilyy neighbor informing me she found them at her doorstep when I wasn't home.

very handy to have around when working on my mini rc trucks
