These screws are crafted from high - quality stainless steel, providing remarkable corrosion resistance. The passivation treatment further enhances their durability, ensuring they can withstand different environmental conditions. This makes them perfect for long - term use when fastening plastic components, maintaining a secure connection without rust or degradation.

With a length range from 1mm to 500mm, these screws offer great versatility. Whether you're working on tiny plastic parts that require a short screw or larger plastic assemblies that need a longer one, there's a perfect fit for your project. The adjustable length allows for precise fastening in various plastic - based applications.

The Torx drive system on these screws offers a more secure and efficient way to install and remove them. The unique six - pointed socket provides a better grip for Torx - tipped tools, reducing the risk of slipping. This ensures a smooth installation process, saving you time and effort, especially when dealing with a large number of screws.

Designed specifically for plastics, the PT style thread - forming feature is a key advantage. As the screw is driven into the plastic, it cuts and forms its own threads, eliminating the need for pre - tapping holes. This not only simplifies the installation process but also reduces the risk of cracking the plastic. The formed threads provide a tight and reliable connection, suitable for a wide range of plastic materials.

These screws are suitable for DIY plastic projects, plastic furniture manufacturing, and small - scale plastic product assembly. Whether you're creating a custom plastic model, assembling plastic furniture, or manufacturing plastic products, our 1mm - 500mm length stainless steel passivation Torx drive thread - forming PT screws are a reliable choice.
