Heat-Set Inserts for Plastic

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

Male Threaded Heat-Set Inserts for Plastic

With the male threaded end on these inserts, mount components directly to plastic parts.

Symmetrical Heat-Set Inserts for Plastic

Quicker to install than standard heat-set inserts, these inserts go in either way—no need to check which end is correct.

Tapered Heat-Set Inserts for Plastic

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.

Male Threaded Tapered Heat-Set Inserts for Plastic

Tapered on one end, these inserts are easy to guide into a hole during installation. The threaded rod on the other end creates an attachment point for components on plastic parts.

Mold-In Inserts for Plastic

Integrate strong metal threads as you make parts through injection molding. These inserts become inseparable from your parts, forming a stronger bond in plastic than heat-set inserts and press-fit inserts.

Heavy Duty Mold-In Inserts for Plastic

Add threads that resist twisting and pulling more than standard mold-in inserts. These inserts have a six-pointed shape and ridges that give ample surface area for contacting the plastic, so they’re strong and sturdy.

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.

Heat-Set Insert Tips

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.
