S-90769A157 Length 38 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Effortless installation in multiple materials without pre-drilling, thanks to the integrated drill tip that penetrates up to 5.25mm thickness.
• Superior corrosion resistance from the zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments.
• High-strength, permanent fastening achieved through the thread-forming design, which creates strong, wear-resistant threads in the base material.
• Wide material compatibility for use in steel, stainless steel, aluminum, fabric, insulation, sheet metal, and wood, offering exceptional versatility.
• Secure and reliable drive engagement with the Phillips No. 3 drive, preventing cam-out and allowing for efficient torque transfer.
• Optimized for metric applications with an M5.5 size and 1.8mm pitch, ensuring precise fit and performance in standardized assemblies.
• Full 38mm thread length provides maximum grip and holding power in a wide range of material thicknesses.

Professional Applications & Engineering Value

This M5.5 metric tapping screw is engineered to solve critical fastening challenges in industrial assembly and construction. Its thread-forming action and drill tip eliminate the need for separate drilling and tapping operations, significantly reducing installation time and labor costs in materials like sheet metal, aluminum, and steel. The zinc-plated steel material offers excellent durability against corrosion, making it ideal for both indoor and outdoor applications. The pan head with a Phillips drive ensures a flush finish and secure fastening in fabric, insulation, and wood, providing a versatile and reliable solution for HVAC, automotive, and general manufacturing where speed, strength, and compliance are paramount.
