HANGLIFE Threaded Inserts for Plastic, M2.5 Heat Set Insert for 3D Printing Components and Plastic Parts - Brass Metric Knurled Nuts (100 Pieces)

Great for putting 3d printed models together

perfect for the job.Used in 3D printed parts mostly servo frames for RC aeroplanes.

Very good quality

I've found myself buying this brand in particular. They are good quality. I have bought large quantities from CNC Kitchen, but sometimes I've needed sizes I didn't have, in a hurry, so I end up in here - choose these every time. I don't put them in hot as I don't personally think that's a good idea. I fit mine using a toggle press and add they go in, you can see them rotating and effectively cutting themselves into the material. A royal pita to get out of something is wrong, so I know they work!

It works what more do you need to know

Very good product, I get through a fair few of these in my 3d prints, these are as good as any others, they set in well and stay in well, the threads are nice and clean and accept the m3 bolts easily.

Just what I needed for various 3D printed projects.They go in and grip nicely using a standard soldering iron tip though they work even better with a dedicated insert tip.

Using a flat end of a soldering iron at 450C made these slide into the PLA like a knife through butter!Probably better quality than the cheap M3 screws i use in them!
