300Pcs Threaded Inserts M2 M2.5 M3 M4 M5 M6 Brass Heat Set Insert for Plastic and 3D Printing Components

Good quality, function as intended, great value

They seem to be built well enough for brass inserts. The size was accurate and they work for the project that I was doing.

Very good and are easy to install with a soldering iron. Can be pressed in cold but an iron makes it so much easier

Works as intended

I had not used these inserts before, but now, with my hobbies, I can't live without them. I used my 3D Doodle pen to heat them and push them in, and it worked great. These are packaged in a nice clear poly case and very well organized. Each compartment is built into the case. Both the outside and the inside of the lid show what is in each compartment.This is the right style to purchase. Each insert has an end that is smaller then the knurled part which makes it easy to set inside the pilot hole I drilled into the plastic. I had an old 3D doodle pen that I have not used for quite some time, and discovered that it is perfect to heating the insert and pushing it into the plastic.Nice little tab so I can hang it on the pegboard of my work bench.

Can't say more it works fits and measurements are accurate

The product quality is very good and the logistics speed is very fast.

Los compré para definir que referencia se ajustaba más a mi necesidad, se ven de buena calidad y la rosca es la adecuada
