HANGLIFE Heat-Set Threaded Inserts, M4 Heat Set Insert for 3D Printing Components and Plastic Parts - Brass Metric Knurled Nuts (100 Pieces)

Fitted well. Nice clean machining and the measurements are as specified. They install easily and hold screws well in the right materials.

There are multiple options to choose from for heat inserts, which are indispensable for anyone who's serious about 3D printing. The quality varies tremendously, so does the price. However, this set checks all the boxes. I waited a bit with the review to test more than 1-2 of them and wow... these are definitely landing on my favorite list! After using over a dozen of them I can confidently say these are great. The thread quality is very good, the dimensional accuracy on the outside is within 0.05mm tolerance, and the brass has no sharp edges on it. They may not be the cheapest set, but the QUALITY is DEFINITELY worth the premium. In addition to being good quality, the ostensibly small touch of including the dimensions and a BIG picture on the packaging makes it extremely easy to identify them in a shop. I no longer need to make a custom label.... these are small things that make using the product way easier. This is my first set of the heat-set inserts from Hanglife, but for sure not the last one!

Threads are very clean & inserts are very easy to install. No issues with the inserts pulling out once installed. Wish there were more larger sized inserts & fewer smaller inserts.

Great product. There is no 1.4mm tip available. Just use the tip of the m2 tip to press this in. It gets it done without issue.

Bought these by mistake.. but will use them in future projects. all other variants of these are awesome!

They work good and are well priced. I recommend designing to pull through what you are heat-setting them into, instead of the same orientation that you inserted them in.

These work as advertised. I needed the M2.5 size, I didn't realize there was a half size... But these will work with my smaller frames

I recently got the HANGLIFE M2 heat-set threaded inserts, and they are just what I needed for my 3D printing projects! The quality is top-notch—these brass inserts are sturdy and durable, ensuring they won't break or deform easily. The installation process is straightforward: just heat them up and insert them into the tapered holes. Once the plastic cools, they hold firmly in place, giving me confidence in my designs. With their smooth, knurled surface and no burrs, they fit perfectly in my prints. Plus, they're compatible with various thermoplastics, making them versatile for different applications. I'm very satisfied with this purchase—definitely recommend these inserts for anyone looking to enhance their 3D printing experience!

Ottimo prodotto. Tuttavia non funzionano nelle stampe 3D in resina. Ottimi nelle stampe a filo! Facili e rapidi da impiegare.

Die Gewindeeinsätze sind eine super Ergänzung für alle, die viel mit 3D-Druck oder Kunststoffteilen arbeiten. Die Messing-Einsätze lassen sich sehr sauber einsetzen und bilden stabile, langlebige Gewinde, die auch häufiges Ein- und Ausschrauben ohne Probleme mitmachen. Die Qualität der Messing-Gewindehülsen ist wirklich gut – sie sitzen fest, drehen sich nicht mit und halten perfekt in PLA, ABS oder anderen thermoplastischen Materialien. Die Lieferung im 50er-Pack ist ideal, wenn man oft Ersatzteile, Prototypen oder funktionale Komponenten herstellt. 👍 Vorteile: • Einfaches Einpressen / Einschmelzen • Saubere Gewinde mit guter Festigkeit • Viel Zubehör für wiederholte Nutzung • Gute Preis-Leistung Ein super Produkt für Hobby-Bastler und professionelle Nutzer gleichermaßen. Klare Empfehlung!

Good product , not expensive and the dimensions are accurate

all good

Does what I need it too when I custom make things on my 3d printer and need two parts connected great quality and good value for money !
