• Superior corrosion resistance from zinc-plated steel construction, ensuring long-term durability in various environments.
• High-strength thread forming creates secure, vibration-resistant threads in materials like steel, aluminum, and wood.
• Wide material compatibility for use in steel, stainless steel, aluminum, fabric, insulation, sheet metal, and wood.
• Optimized drive engagement with Phillips No. 2 drive for efficient installation and reduced cam-out risk.
• Full-threaded design maximizes grip length and pull-out strength across the entire 50mm shank.
• Regulatory compliance meets DIN 7504 N, RoHS 3, and REACH standards for global industrial acceptance.

Professional Applications & Engineering Value

These M4.2 tapping screws deliver exceptional value in industrial assembly by combining a thread-forming design with a self-drilling tip. The zinc-plated steel construction provides reliable corrosion protection, while the fully threaded metric profile ensures maximum holding power in demanding applications. Engineers benefit from reduced installation steps when fastening sheet metal, aluminum frames, or wood components, as the screw drills, taps, and fastens in one operation. This efficiency is critical in high-volume production environments, minimizing tool changes and speeding up assembly lines. The pan head with Phillips drive offers a low-profile, secure fit that withstands vibration, making these screws ideal for HVAC, electrical enclosures, and machinery where reliability is paramount.

Specification Summary & Compliance

This M4.2 x 50mm screw features a fully threaded shank with an approximate 1.4mm pitch and right-hand thread direction. Manufactured to DIN 7504 N specifications for thread-forming tapping screws, it ensures precise dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from hazardous substances and suitable for use in regulated industrial and consumer applications.
