The kit is nice. I have used some of the screws to put together some of my 3d print projects. I like how it came with some Allen wrenches also. A nice kit, worth the money.

Great pack. Just keep in mind the sizes and lengths available in the package. Check the description and make sure it's what you need.For me, this pack was a great mix of pieces in the M3 size range and for the price it was well worth it.Threads are clean and all pieces are the correct size. Available lengths are good and I've used at least one of each piece in the kit at this point. Works great. Would buy again.

This kit is a lifesaver. It’s got every screw size I’ve ever needed, plus handy hex wrenches. Everything is neatly organized, so no more digging through random bins. The screws are good quality and perfect for all kinds of projects - like 3D prints. Great value for the price.

I researched several options for some time as I needed a selection for future unknown projects. This has worked perfectly and I expect it will for some time.

The main thing you should know is that the paint job isn't that good and it smells really strong. If you dont care about the smell or looks this is a great set of durable screws with a good verity for 3d printed projects.

I was looking for some small SAE screws to fix my screw driver, and found this set of screws with a good price when it was on-sale on Amazon. The range of sizes of the screws that fit my need for many projects around my house. The quality of the screws are good. However, the plastic case is too hard and fragile. When I received the package, the case had a broken hinge even though it was wrapped in a plastic bag. I have to put a piece of clear tap to hold the case cover. Anyway, I give it five stars for the quality of the screws.

Contacted seller to give feedack on thier packaging.All the smaller nuts/washers/bolts were scattered around the plastic holder. Took about 30-40 minutes with a magnetic tool to clean/sort this mess up.Otherwise, great selection.Just what I needed.
