For some applications where, for example, stress-prone or brittle glass-filled thermoplastics are specified, Tappex has developed special threaded inserts just to suit these more demanding of plastics. These threaded inserts can be supplied in either Brass or Steel(s) for post-mould / press in installation, typically into either machined or moulded plastics at ambient temperature, with heat applied.
Thread Forming Screws
Installed into drilled or moulded holes - wide variety of applications. Tappex TPX® thread forming screws are produced by cold forging from bar or wire-stock and therefore have excellent mechanical properties with minimum residual stress & high strength suitable for installation into thermoplastics.Product Details
