Heat-Set Threaded Inserts (8-32 Threads)
Heat-Set Threaded Inserts are a great option for 3D printed parts or making repairs to any thermoplastic part. They provide a much stronger connection than simply threading screws into the plastic. Brass will also last much longer than plastic threads and is less likely to cross thread which makes them ideal for parts that are assembled and disassembled often. These inserts can be easily and quickly installed by heating them with a standard soldering iron on a low-heat setting and using the soldering iron's tip to press the insert into place. The melted plastic will flow around the knurls and ridges on the insert as it is pressed in and solidify when cool, locking it in place. These inserts have #8-32 SAE (Imperial)threads.

Design tips for using Heat-Set threaded inserts
When fastening multiple parts together, make sure the the diameter of the screw hole on the part lying directly against the part with the heat-set insert is smaller than the outer diameter of the insert. This will ensure that the clamping force generated by tightening the screw does not pull the insert out of place.
