Thread inserts for plastics

Tappex® offers a broad range of threaded inserts for plastics to suit mould-in and post-mould installation dependant customer’s application requirements as well as their in-house manufacturing process

Thread inserts for metals

Tappex® have thread inserts designed for critical applications in light-metal alloys such as: Aluminium, Zinc & Magnesium when they are subsequently manufactured as castings, extrusions, machined or fabricated parts.

Thread inserts for woods & composites

Tappex®, as a fastenings technical-leader,  has identified bespoke requirements for mechanical joining of contemporary materials such as glass-reinforced plastics (GRP), combinations of metal alloys / plastics, structural foams / woods / paper-based sandwich constructions and increasingly carbon / kevlar-fibre laminated constructions.

Thread inserts for special applications

For applications where stress-prone or brittle, glass-filled thermoplastics are specified, Tappex have developed special-variant threaded inserts to suit these more demanding materials. Such threaded inserts can be supplied either in either brass or steel material(s) for post-mould ‘self-threading’ and/or ‘press-in’ installation. Typical applications are either machined or moulded plastic(s) applications at ambient temperature or installed with heat applied.

Installation tooling for thread inserts

The Tappex range of installation tools include: Heat Installer (074 HIV), FlexiArm® (035 series), Production drivers (029 series) and Hand tools (030/031 series) which enable the post-mould installation of threaded inserts by manually for 1-off and / or medium volume or batch production sutiable for a wide range of plastics, laminates, woods & light-metal alloys.

What Others Say

Charlie Woodsman


While inserts from other companies have damaged the materials I work with, Tappex identified a product which meets my technical needs perfectly. The Tappex staff were knowledgeable, courteous and extremely helpful.


Anytime! your whole team has been nothing but kind, helpful and cheerful, and it has really helped to reduce the amount of panic at this end.

CEng FIMMM Engineering Consultant.

I would like to recommend the services both technical and sales support I have received from Tappex.
I received concise answers to my questions regarding installation tolerances they also suppled CAD data which saved my further time.
After all the support they were still happy to quote for the small quantities involved with my current design work.

A first rate job by all involved, thank you.
