Work great! This kit has all the sizes. The case is nice and everything works as it should.

These were my first try and threaded inserts, and I've been well pleased. I use them for 3D prints that need to be taken apart at times, and these work perfectly. It took me a little work with my prints to make the hole the right size, and to make sure I had a long enough hole, but after a couple of videos, they are really easy to use.

Great for 3d printing. I printed a spool refiller for my 3d printing. These inserts went into the print easily.

Needed these for my 3d printingThey work as intended

Love the fact that these have a flat base on them! They allow me to slide them into printed parts and get them level prior to setting them in. SUCH a great feature. A lot of other inserts don't offer this and I don't understand why.These mount pretty quickly with a good soldering iron and tip... Really appreciate the build quality and fit. Perfect for what I needed!

Nice heat inserts, very consistent

nice kit, fit well for my project, worth the price.
