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

Perfect for SCx24 RCs
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.

Great inserts!
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.

Easy solution to adding sturdy threading.
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.

Good M3 inserts
Worked well for Voron spec parts.

They work, but design could be better
These heat inserts seem to be quite strong once melted into the plastic, but I found that the design makes them difficult to line up. Heat inserts should have tapered bottoms so they can sit in the hole that you melt them into, but these have a hard lip that doesn't fit in smaller holes. Despite this, you can use them by lifting them up with the soldering iron and lining it up that way, but be careful to line it up properly first, as these transfer heat quite well and will begin melting into the plastic very quickly.

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!
