Good values and fits my needs.

box arrived cracked and leaking little flat washers all over the kitchen counter. Not the fault of the box, just typical shipping damage that can happen. Arrived quick and seems to be a good addition to the bolt bin.

Exactly what I needed for projects, got it for my 3D printer specifically. Great variety and comes in a neat, organized box, but box was slightly damaged in shipping.

This is a great little kit for the money. Lots of variety in sizes. The hardware quality is very good.The hardware came fairly well separated.That being said, all of the screws, nuts and washers were filthy oily though. I could not handle them without getting oil on everything. This is fine if you are working on machinery, but I am using these with 3D printed parts. The oil and the dirt just goes everywhere. I ended up washing them all in a degreaser. I'm sure this is for shipping, as they do not want the parts to rust though I'm not even sure what the liquid is. Oil, machining oil, black oxide processing finish...??The included plastic box is not great as many of these assortment kits come in. They use insertable dividers that just lift right out. Mixed hardware right off the bat. I ended up transferring all of the screws to a better container with individual compartments.All in all the hardware kit was a decent. Don't be afraid to buy it, just be aware of the condition it may come in.

All pieces accounted for

It was well wrapped for shipping but the weight of the bolts knocked down all the dividers in the box and all the sizes were mixed together. It needs either a stronger divider box or each size bolt in a separate bag like the washers that can then be put in the appropriate cells. No amount of bubble wrap will stop the bolts from moving inside the plastic box and the dividers are too thin and flexible and get knocked out of their grooves.

Great variety of lengths and plenty of nuts

Most flight sim hardware mounting using M4 screws. I'm using these to mount stuff to my honeycomb alpha and bravo as well as to mount one saitek panel to another one below it. I like that these are basically setup like thumb screws with some texture on the sides to make them easy to turn with fingers, but that you can then also finish tightening them with an included allen key. These are also excellent value. Mine arrived with the plastic case a bit cracked along the back right edge, but I don't really consider that a big deal.
