S-90380A367 Length 18 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Excellent thread-forming capability creates strong, permanent threads in plastic materials without pre-tapping
• Optimized drill bit compatibility with 2.6mm diameter for precise installation and reduced assembly time
• Enhanced driving efficiency with Phillips No. 2 drive for secure tool engagement and reduced cam-out risk
• Maximum holding power through fully threaded design that distributes load evenly across the entire fastener length
• Reliable performance with consistent 1.57mm pitch threads ensuring predictable installation and removal torque
• Broad material compatibility specifically engineered for plastic applications with minimal risk of material cracking

Professional Applications & Engineering Value

These M3.5 thread forming screws deliver exceptional engineering value in plastic assembly applications where traditional fastening methods often fail. The TRS (Thread Rolling Screw) design with zinc-plated steel construction eliminates the need for pre-tapped holes, reducing assembly steps and labor costs. The thread forming technology displaces plastic material rather than cutting it, creating stronger threads with superior resistance to vibration loosening. The fully threaded configuration ensures maximum engagement in various plastic thicknesses, while the pan head style with Phillips drive provides reliable installation without specialized tools. This combination addresses critical industrial challenges including material stress reduction, installation efficiency, and long-term fastener reliability in plastic components across automotive, electronics, and consumer goods manufacturing.

Specification Summary & Compliance
