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 applications in very light but mechanically-stiff structures. Tappex® continues to meet these new application challenges for OEM and other critical industrial applications.
Tappex® thread inserts for woods & composites fall into 3 broad categories:
– self-threading brass Foamserts®
– steel Trisert-3s®,
– 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.
