Heat-Set Insert Tapered, M3-.5 Internal Thread, 3.8mm L (x20)

Integrating strong and reliable screw threading into your 3D designs is easy! Once integrated into your work flow, you'll be quite attached.

Use brass 3D printer internal threading inserts to add threaded mounting points to your 3D printed objects. While it is possible to thread bare plastic, repeated use can cause wear leading to threading failure. Threaded Heat-Set Inserts are designed to be heated past the plastic glass transition temperature and inserted into the plastic part.
