What are PT Thread Screws?
Most plastic assembly failures come from cracked bosses, plastic debris and loose screws. Our PT thread forming screws solve these common production pain points perfectly. Different from standard cutting self-tapping screws, our PT screws form threads by extruding plastic instead of cutting it. No cracks, no dust, no loose fit. Stable performance for mass electronic assembly. Factory direct supply, in-stock standard sizes and custom options available.

Learn more about PT Thread screw
● If you are troubled by high defective rates in plastic product assembly, this PT thread forming screw is your ideal solution.
● Conventional ST self-tapping screws cut plastic during installation. They produce fine plastic chips that may cause short circuits in electronic devices. The sharp thread also generates huge radial pressure, easily cracking thin plastic walls, leaving white marks and leading to thread loosening after vibration.
● Our Phillips pan head PT screws adopt professional plastic extrusion thread design. With a optimized blunt tip and wide triangular thread, it squeezes plastic material to form precise, tight internal threads without cutting any material. Zero debris is produced during assembly. The uniform pressure distribution protects thin plastic bosses from cracking, whitening or deformation.
● Compared with ordinary self-tapping screws, this PT screw delivers higher pull-out force and better vibration resistance. The tight thread fit ensures long-term stable locking, greatly reducing after-sales failure and product rejection rate.
● It works perfectly with ABS, PC, PP, PVC, Nylon and most thermoplastic materials. Widely applied for charger housings, power adapters, Bluetooth accessories, small home appliances, lighting fixtures, plastic toys and other consumer electronic plastic assemblies.
● We provide carbon steel and SUS304 stainless steel options with zinc plating, nickel plating and black finish. All finishes meet RoHS and REACH standards for global export. Common sizes M2, M2.3, M2.6, M3, M3.5, M4 are well stocked for fast delivery. Custom lengths and non-standard specifications are supported.
