A specially shaped soldering iron tip designed for pressing M5 heat-set threaded inserts into 3D-printed or injection-moulded plastic parts. The vertical shoulder wall prevents the insert from sticking to the tip when you pull the iron away, and helps ensure the insert goes in straight every time.

Compatible with any soldering iron that accepts Hakko-style tips. Simply swap out your regular soldering tip, heat up the iron, and press the insert into a pre-drilled hole in your plastic part. Once cooled, you have a strong, reusable machine-screw thread embedded in the plastic.
