S-90769A116 Length 19 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling operations with an integrated drill tip that penetrates materials up to 2.4 mm thick, saving time and labor costs.
• Superior corrosion resistance provided by zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
• High-strength thread forming design creates secure, vibration-resistant threads in steel, stainless steel, and aluminum without tapping.
• Optimized Phillips No. 2 drive allows for efficient installation with standard tools, reducing cam-out and improving torque transfer.
• Full thread engagement along the 19 mm length ensures maximum holding power and uniform stress distribution.
• Pan head design with 7.5 mm diameter offers a low-profile, wide bearing surface for secure fastening without sinking.
• Compliance with DIN 7504 N standards guarantees dimensional accuracy and performance consistency for professional applications.

Professional Applications & Engineering Value

These M3.9 self-drilling tapping screws are engineered to streamline assembly processes in demanding sectors such as metal fabrication, HVAC, and construction. The zinc-plated steel material provides essential corrosion protection, while the precision drill tip and thread forming capability allow direct installation into steel, stainless steel, aluminum, and sheet metal up to 2.4 mm thick. This eliminates the need for separate drilling and tapping steps, reducing assembly time and minimizing tool wear. The fully threaded metric design with a 1.4 mm pitch ensures strong pull-out resistance and reliable performance in industrial fastening applications, from structural frames to electrical enclosures.

Specification Summary & Compliance

This screw features an M3.9 size, 19 mm length, and 1.4 mm approximate thread pitch with right-hand thread direction. It meets DIN 7504 N (equivalent to ISO 7049) specifications for dimensional tolerances and thread forming performance. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety regulations for industrial use.
