Bought these for some 3d prints I made and they worked beautifully. Be sure to buy the heated inserter though, as well as the various sized tips for it. This make installation almost foolproof. Great quality and a good quantity in this kit.

Great quality, comes with adapters to use on the soldering iron, zero complaints.

Worked perfectly to heat sink into 3d printed things. Perfect fit.

I haven't used any yet, so I'm not sure as what to expect. Good amount of different sizes which was what I was looking for anyway.

Perfect assortment for a variety of small to larger machined mm hex, flat head screws. Perfect for Hobbiest working with plastic and 3D products. Great price, fast shipping.

Threads are true to size, no problem setting them in my 3d print projects. Lots of pcs for the $.

Very nice set. Worked well.
