Heat-Set Inserts for Plastic

Install these inserts into plastic parts to create a secure base for fasteners.

The tapered shape makes it easier to guide these inserts into a hole during installation. Use a drill bit to create a straight hole, then taper the top half.

Tapered Heat-Set Insert Assortments
for Plastic with Installation Tools

Assortments include various sizes of inserts, a soldering iron, a ceramic insulation tube, and installation tips.

Aluminum Unthreaded Inserts for Plastic

These aluminum inserts are lightweight, nonmagnetic, and mildly corrosion resistant.

Steel Unthreaded Inserts for Plastic

A zinc-plated finish gives these steel inserts mild corrosion resistance.

Installation Tips for Heat-Set Inserts

Attach these installation tips to a soldering iron. The tips transfer heat from the soldering iron to the insert, softening the surrounding plastic. When the plastic cools, it solidifies around the insert to keep it secure.

Extraction Tips for Heat-Set Inserts

Extract heat-set inserts by attaching these tips to a soldering iron. The tips transfer heat from the soldering iron to the insert, softening the surrounding plastic to loosen the insert so it can be removed.
