High Precision PT Screw Low Stress Thread Forming Self Tapping Screw for Thermoplastic Industrial Assembly

1. Product Overview

Our PT screw is a professional thread forming self tapping fastener specially developed for thermoplastic assembly. With optimized thread design and precise production technology, this series of PT screw effectively reduces radial stress on plastic workpieces, avoids boss cracking, and delivers outstanding clamping force and self locking ability. As a mainstream industrial fastener, PT screw has been widely adopted in electronics, home appliances, automotive accessories and general industrial manufacturing fields. We adhere to strict production standards to ensure every PT screw keeps consistent quality and stable performance in long term use.

2. Core Features & Competitive Advantages

Compared with ordinary screws, our PT screw owns multiple prominent advantages for plastic connection:

1. Optimized Thread Design: The special thread profile and flank angle help plastic material flow smoothly during tapping, greatly lowering installation torque and assembly difficulty.
2. Low Radial Stress: The unique structural design reduces expansion force on plastic holes, effectively preventing workpiece damage and boss rupture.
3. Excellent Anti Loosening Performance: The matched pitch angle realizes reliable self locking, which can resist vibration and external force to maintain long term connection stability.
4. Superior Material & Corrosion Resistance: We select high quality carbon steel and stainless steel as raw materials. The surface treatment enhances rust and corrosion resistance, suitable for complex working environments.
5. High Dimensional Precision: Every PT screw is processed by automated equipment, with strict tolerance control to guarantee perfect matching with assembly holes.

All above advantages make our PT screw more practical and durable than common fasteners, helping clients reduce defective rate and improve assembly efficiency.
