• Environmental compliance assurance with RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

This M2.63 TRS thread forming screw delivers exceptional value in plastic assembly applications where reliable fastening is critical. The 18-8 stainless steel construction provides superior corrosion resistance, making it ideal for electronics enclosures, automotive components, and consumer products exposed to moisture or harsh environments. The Tri-Lobe shank design displaces plastic material during installation, creating permanent, high-strength threads that resist vibration loosening. The Torx Plus IP8 drive system ensures maximum torque transfer while reducing cam-out incidents that can damage screw heads and compromise assembly integrity. With its 4mm length and 1.06mm thread pitch, this screw offers precise engagement in thin plastic sections where space constraints demand compact fastening solutions.

Specification Summary & Compliance

This metric thread forming screw features M2.63 diameter with 1.06mm thread pitch and 4mm length with fully threaded configuration.
