Used on parts for High School competition robot. The M4 have better grip and are more of a go to size but, if you have to use M3 these work very well. M3 is common on many servo horn mounts but if you just want to try it out or have a choice use the bigger size, M3 pulls out easier than M4.

Good solid inserts. Use them a bit and I still have a ton left over so this is a very nice amount. Never had these fall out or get over torqued in 3d printed parts in both PLA and ABS, so they seem pretty effective compared to other designs of heat set inserts.

Not much to say, they work as intended.

I used these inserts in my 3d Printed projects and they work very well. Just using the tip of my standard soldering iron, I was able to heat them up within seconds to push them into my printed part (made from PETG material). They seem to hold up well for lighty-loaded applications (like for a box cover). Note, that these are really tiny, smaller than I expected. In the future I might go one size up for use with electronics box enclosures.

I needed some threaded inserts for some 3d print jobs I have lined up and these so far have worked great. The outer profile seems to be holding very well in the plastic and they take some force to remove. In most cases, it just breaks the plastic if you try to pull one out. This IMO is a great thing, it means that they are working.
