Professional Applications & Engineering Value

These M3.5 TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications where traditional fastening methods often fail. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for durable plastic connections. The thread forming design eliminates the need for separate tapping operations by displacing plastic material to create precise, strong threads that resist stripping and loosening under vibration. The combination of Phillips drive and flat head profile ensures secure installation and flush seating in plastic components ranging from electronic enclosures to automotive trim pieces. With right-hand threading and fully threaded configuration, these screws deliver consistent clamping force across the entire engagement length, preventing material stress concentration and ensuring reliable performance in demanding plastic fastening scenarios.

Specification Summary & Compliance

These metric M3.5 x 16mm TRS tapping screws feature standard thread forming design with approximate 1.57 mm thread pitch and blunt tip for optimal plastic penetration. Manufactured to precise dimensional standards with 7.3 mm head diameter and 2.5 mm head height for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and market acceptance. Designed specifically for use with 2.6 mm drill bits in plastic materials, providing reliable fastening solutions for industrial applications requiring regulatory adherence and technical precision.
