HANGLIFE Heat-Set Threaded Inserts, M2.5 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.

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.

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.

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 worked quite well. Great product.

Worked well for Voron spec parts.

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.

Easy to use and heat up quickly
