Professional Applications & Engineering Value
These M2.5 TRS tapping screws are specifically engineered for plastic assembly applications where reliable fastening is critical. The thread-forming TRS design eliminates the need for separate tapping operations, reducing assembly time and costs while creating strong, vibration-resistant connections in plastic components. The 18-8 stainless steel material provides excellent corrosion resistance, making these screws ideal for applications exposed to moisture or harsh environments. The flat head Phillips configuration with 90° countersink ensures a flush finish that maintains aesthetic appeal while the 1.12mm pitch and fully threaded design distribute stress evenly, preventing material cracking and ensuring long-term joint integrity in plastic assemblies.
Specification Summary & Compliance
This M2.5 x 18mm TRS flat head Phillips tapping screw features metric dimensions with standard thread forming design, right-hand threading, and blunt tip configuration. The screws maintain precision manufacturing standards with compatibility for No. 45 drill bits (0.082" diameter) and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest industrial safety and sustainability requirements for professional applications.
