Review: High-Quality Heat Inserts - Overall, I’m very happy with these heat inserts. They shipped quickly and arrived in good condition with no issues. In use, the machining appears to be high quality and the knurling is clean and consistent. Screws thread in smoothly without binding or cross-threading. I primarily use these for 3D printed parts and have not experienced any fitment or durability problems. They perform exactly as expected and I would recommend them to anyone installing threaded inserts in 3D prints.
Review: Secure and consistent quality - These are a more secure design than the ones with vertical ridges. They are easy to guide in with my soldering iron, and I've never had any issues with rough threads.
