Heat the insert gradually with a soldering iron or dedicated heat-set tip. Press the insert straight into the part without excessive force. Stop when the insert is flush or positioned at the intended depth. Allow the plastic to cool completely before installing a screw. Important NotesConfirm that the printed part has enough wall thickness and pocket depth for the tall insert. Test fit and installation temperature on a scrap print before installing into a finished part. Excessive heat or pressure can deform the surrounding plastic.What’s IncludedOne package of approximately 100 tall M3 heat-set threaded inserts.
