S-90769A129 Length 32 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with an integrated 9mm drill tip that penetrates up to 3mm thick materials, saving significant labor time and tooling costs.
• Superior corrosion resistance from the zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments.
• High-strength, secure fastening achieved through thread-forming technology, which creates strong, durable threads in the base material for excellent vibration resistance.
• Broad material compatibility for use in steel, stainless steel, aluminum, sheet metal, fabric, insulation, and wood, offering versatile application solutions.
• Optimized drive engagement with a No. 2 Phillips pan head design, providing a secure grip and reducing the risk of cam-out during installation.
• Full-thread engagement along the 32mm length ensures maximum pull-out strength and a uniform distribution of clamping force.
• Guaranteed quality and safety by complying with DIN 7504 N and ISO 7049 standards, and being RoHS 3 and REACH compliant.

Professional Applications & Engineering Value

This M4.2 x 32mm self-drilling screw is engineered to solve the critical industrial challenge of efficiently joining thin-gauge metals and other materials without pre-punched holes. The zinc-plated steel body provides a robust foundation, while the specialized drill tip and thread-forming design work in tandem. As the screw is driven, the tip accurately drills a pilot hole, and the metric thread with an approximate 1.4mm pitch immediately forms a perfect mating thread. This cold-forming process displaces material rather than cutting it, resulting in a tighter fit, higher resistance to loosening from vibration, and stronger joints in sheet metal, HVAC ductwork, and metal framing applications. The Phillips pan head offers a low-profile, finished appearance and reliable drive transfer, making it an indispensable component for assembly lines and on-site construction.
