Threaded Inserts M4 (10 pack)

These threaded inserts are a must have for DIY 3D Printed Part building.
Using only a soldering iron, they can be heat and press fit into a hole in any 3D Printed part.
The plastic cools around the insert and sets it in place, adding an exceptionally strong screw thread to your 3D Printed part.

These threads are made from a high strength and corrosion resistant brass that uses kurled fins to ensure its grip onto the plastics.
