PT ALTERNATIVE SCREW
Fastener for plastic application
It is specially designed for thermoplastic material. The special screws solved problems such as plastic cracking, stress concentration, and unreliable connections caused by traditional screws.
The design includes two features, 30° thread angle and double core diamer. The goal was to minimize stress on the surrounding material while forming internal threads, thereby ensuring connection reliability and long-term stability.
This innovative design not only improved product quality but also reduced production costs by decreasing the need for metal inserts。
