Standard ST screws cut into the plastic material during driving, creating swarf, debris, and high radial stress that often cracks plastic bosses. PT screws are designed to extrude the plastic, creating tight internal mating threads without cutting chips or inducing structural cracking.
Yes. Because PT screws form threads through material displacement rather than thread-cutting, they generate zero plastic shavings or dust, completely preventing internal electronic short circuits caused by debris.
PT thread screws are ideally engineered for thermoplastics including ABS, PC, PP, PVC, PA (Nylon), and various plastic blends widely used across consumer electronics and domestic appliances.
Yes. The thread profile provides a compact, continuous grain flow in the molded plastic, which delivers significantly higher pull-out resistance, lower driving torque, and superior back-out resistance against continuous vibration.
Yes, we provide both Carbon Steel and SUS304 Stainless Steel with customizable platings including Zinc, Nickel, Black Oxide, and Passivation. Non-standard dimensions, lengths, and OEM/ODM specifications are fully supported.
Yes, free stock samples are provided for dimensional verification and structural assembly testing, backed by flexible MOQs to assist trial production runs.
