VIGRUE 1080Pcs M4 M3 M2 Socket Head Cap Screws Bolts Nuts Washers Assortment Kit with Allen Wrenches, Small Metric Screws Set Assortment, Black Screws Class 12.9 Alloy Steel

Package arrive securely closed. Inspection reveal the individual sizes were packaged separately and arranged in separate container bins. The accompanying tools and tweezers fit cleanly inside the storage container. The storage container was organized so that each size had its own section for the various lengths along with the proper size washers and nuts. The container lid had two locking tabs that held the lid closed. When closed, the lid prevented the parts from migrating from one bin to another. The locking tabs did not appear to be sturdy enough to hold the lid closed if the container was dropped from any height. The caveat to this comment is the contents weight is such that even heavier duty container would fail if dropped. All in all, I am quite pleased with the quality of the product and their performance in the projects they were purchased for.

All the sizes allow the nut to spin all the way up until it's a tight interference fit with the head. The threads are smooth and free of burrs, and the surface finish is very smooth. The nuts are not prone to cross-threading from hand starts, cross thread attempts come up against a hard stop, so it's obvious it's not going in right, and no wondering if it's just a little tight before you realize the screw is ruined. The caps on the M3 and M4 screws are slightly narrower at the surface that mates with the load, which is nice for circuit boards that I want the smallest possible displacement of components for screw holes. The M4 wrench was fine. The M3 wrench had a little lip on the short leg that kept it from going into the socket, but was remedied by 10 seconds with a bit of sandpaper. The M2 wrench was slightly small for the socket, but it still transmits torque just fine and for the tiny amount of torque required for an M2 screw, it's not a real complaint. Overall, these are excellent. I see in other reviews there are 2 complaints that come up for screw assortments. Either the screws are all mixed up and need sorting, or they all come in little bags that need to be unpacked. These come in little bags, which keep them from getting mixed up in shipping (the shipping process is never gentle) and, at least in my opinion, is faster to pour out from the bags than having to sort all the bins. Also know what you are buying, the little screws are very tiny. Perfect for me, but I see a lot of reviews for screw sets that say they are too small. M4, M3, and M2 are sizes, look up how big they are if you aren't sure.

Has everyth8ng I ne3d for my ender 3 pro, well organized

Nice to have around for 3d printer repairs and such. Just check each one before you use it. The hex pockets on some are shallow or off size, and may result in them stripping out.

Variety is truly spice of life....you can never have too many nuts and bolts.. I'm a repair tech.

This is not the first assortment kit I bought from this brand and it is not going to be the last kit. So far, I am happy with all the kits I bought from this brand. They works great and price is very good.Ever since I got my first 3D printers, I often need different type of small screws, nuts and bolts. And often the 3D models I download use metric size so I am glad I picked up few kits. And they are much cheaper than those I got from the local hardware chain.This kit has most of the size I need. Especially when I need some for electronic projects with 3d printed parts or cases. If you own a 3D printer and into electronic stuff, get this.

I have bought several screw assortments in the past where the parts were mixed inside the box, or the box cracked in shipping and dumped the contents into the shipping box, or worse yet the set did not contain the parts listed, but many were substituted.This box arrived undamaged, in a good quality assortment box. Each size screw came in its own bag, so even if the box cracked and opened during shipping, you would not have to sort out a pile of random screws.The assortment box has removable vertical partitions whit stay in place pretty well. I would only worry about the washers slipping under the partitions in this box. (an M2 washer is pretty thin).The screws are glossy black, not the usual flat black that I expect from a black oxide finishThe only issue I found is that not all the M2 screws use the same size driver. Some use 1.5mm, and some 1.27mm. A rather odd inconsistency.The box included Allan wrenches (coal to Newcastle), and a pair of cheap tweezers that are perfectly adequate to grab any size screw, nut, or washer out of its bin.

I really like the available selection of this well made bolt kit, even though it goes from M2-M4. They seem to be machined very well. I like the storage kit the bolts come in, along with the index attached to the inside of the lid. Smart idea !

Not sure what the complaints are about... None were rusty, covered in oil, or mixed up. Everything came clean, each size in its own Ziploc bag. Dividers seem to fit snug enough that stuff won't get mixed up between compartments.

Très bon produit, sert bien pour la réparation de vélo ou autres !

Gute Qualität, gut und übersichtlich sortiert, Top Ware, immer wieder gerne

Good product but the little bags are annoying
