S-94209A690 M4 x 25 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP20/T20 drive, reducing tool slippage and extending bit life during high-torque applications
• Exceptional holding power in soft materials thanks to the tri-lobe shank design that displaces material to create secure, vibration-resistant threads
• Reliable corrosion resistance with zinc-plated steel construction, ensuring long-term performance in various industrial environments
• Optimized for aluminum, brass, and copper applications with thread-forming design that eliminates the need for pre-tapping, saving installation time
• Full-length threading provides maximum engagement and pull-out strength across the entire fastener length
• Coarse 0.7mm pitch enables faster installation while maintaining strong holding capability in softer materials
• Pan head design offers a low-profile finish with good bearing surface for secure fastening

Professional Applications & Engineering Value

These M4 Torx Plus tapping screws are engineered specifically for challenging aluminum, brass, and copper applications where traditional fastening methods may fail. The tri-lobe shank cross-section and thread forming technology work synergistically to displace material rather than removing it, creating stronger, more reliable threads that resist loosening under vibration and thermal cycling. This design eliminates the common issues of stripped threads and poor holding power in soft metals, while the Torx Plus drive system ensures maximum torque transfer without cam-out, reducing assembly time and improving worker safety. The fully threaded configuration with coarse 0.7mm pitch provides complete engagement along the entire fastener length, making these screws ideal for electronics enclosures, automotive components, and machinery where vibration resistance and structural integrity are critical.

Specification Summary & Compliance

These metric M4 x 0.7mm pitch x 25mm length screws feature a Class 6g thread tolerance with length tolerance of -1.2 to 0mm, ensuring precise dimensional accuracy for consistent performance. Manufactured to metric thread standards with right-hand threading and blunt tip configuration, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making them suitable for use in regulated industries and international markets. The zinc-plated steel construction provides corrosion protection while maintaining the mechanical strength required for demanding industrial applications.
