Perform well. - Fitted well. Nice clean machining and the measurements are as specified. They install easily and hold screws well in the right materials. Review: Reliable, consistently sized, and fairly priced inserts - 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! ## Features - Perfect Fit for Your 3D Printed Parts: Retrofit your 3D printed components seamlessly with our threaded inserts, effortlessly embedded using heat or ultrasound into blind- or through-holes.
