- Efficient thread forming in plastics using the TRS design to create strong, reliable threads without pre-tapping, reducing assembly steps.
- Secure and stable fastening with a fully threaded M4 x 18mm shank, ensuring maximum grip and pull-out resistance in plastic materials.
- Easy installation and reduced cam-out provided by the No. 1 Phillips drive and pan head, allowing for high torque application and streamlined assembly.
- Consistent performance and compatibility with a standard 7mm head diameter and blunt tip, preventing material splitting and ensuring precise placement.
- Environmental and regulatory compliance meeting RoHS 3 and REACH standards, ensuring safety and suitability for various industrial applications.
Professional Applications & Engineering Value
These M4 thread forming screws are specifically engineered for plastic assembly applications, where traditional fasteners may fail. The 18-8 stainless steel material offers excellent strength and corrosion resistance, crucial for outdoor or humid conditions. The TRS (Thread Rolling Screw) design with a blunt tip and fully threaded profile displaces plastic material during installation, creating a tight, vibration-resistant fit that eliminates the need for inserts or adhesives. This reduces assembly time and costs while providing high pull-out strength, making them ideal for electronics enclosures, automotive components, and consumer goods. The Phillips drive and pan head ensure easy driving and a low-profile finish, enhancing both functionality and aesthetics in plastic fastening solutions.
Specification Summary & Compliance
This product adheres to standard metric dimensions with an M4 screw size and 18mm length, featuring a fully threaded shank for consistent performance. The thread forming method is designed for use in plastics, compatible with a No. 30 drill bit (0.1285" diameter). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
