Professional Applications & Engineering Value
These M4 thread forming screws are specifically engineered for plastic assembly applications where reliable fastening is critical. The 18-8 stainless steel construction provides excellent corrosion resistance, making these TRS screws ideal for electronics enclosures, automotive components, and outdoor equipment where environmental factors are a concern. The thread forming design eliminates the need for separate tapping operations, reducing assembly time and costs while creating strong, vibration-resistant connections in thermoplastic materials. The Phillips drive system with No. 1 size ensures consistent torque application, while the blunt tip prevents material cracking during installation, making these metric tapping screws perfect for high-volume production environments.
Specification Summary & Compliance
These M4 x 30mm thread forming screws feature precise metric threading with approximately 1.79mm pitch and fully threaded shank design. Manufactured to TRS (Thread Rolling Screw) specifications for plastic applications, they comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The screws are designed for use with No. 30 drill bit (0.1285" diameter) and feature standard pan head profile with 7mm head diameter and 2.8mm head height for consistent performance across industrial applications.
