Tappex® provides solutions with its threaded fasteners to meet the demanding requirements found when seeking to mechanically assemble certain materials and/or combinations of those materials including: glass reinforced plastics (GRP), composite or combination(s) of metal alloys / thermoset plastics / structural foams / wood laminates / paper-based sandwich constructions. Increasingly OEMs & their supply chains are also specifying other materials such as carbon fibre & kevlar reinforcements for application in very light but mechanically-stiff structures. Tappex continues to meet these new application challenges for OEM and other critical industrial applications.
Tappex threaded inserts for woods & composites fall mostly into 3 broad categories:
- Self-threading brass Foamserts
- Steel(s) Trisert-3 inserts
- Case-hardened screws and special rivet nuts (with patented bulge control feature).
Design guidance is available in all instances.
Tappex, in future, will respond with new fastening solutions in the emerging area of ‘light weight materials’ in structural applications.
