Heat set Insert

Heat set inserts are integral to adding threaded holes and bolted connections to a variety engineering parts easily.

  • Pack of 50 pcs
  • Dimensions are M3 x 5mm x 4mm
  • Bottom portion of the heat set insert is 4.2mm wide to help with alignment during installation

These can be easily inserted into plastic parts by heating a soldering iron to around 190C (374F) and pressing the tip through the hole and into the plastic. If you have a short stubby tip that would work best so you don’t poke through the hole and into the plastic directly. To make the connection even stronger try putting the insert on the other side of the object instead of the face. This can greatly increase the strength of the connection dramatically.
