S-90769A131 Length 38 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with an integrated 9mm drill tip, saving time and labor costs in assembly operations.
• Superior material penetration up to 3mm thickness in steel, stainless steel, aluminum, and wood for versatile application use.
• Enhanced corrosion resistance from the zinc-plated steel construction, ensuring long-term reliability in various environments.
• High-strength thread forming creates secure, vibration-resistant fastenings in ductile materials without needing a tapped hole.
• Optimized for efficient driving with a Phillips No. 2 drive, providing a common and reliable interface for high-torque applications.
• Full-threaded design maximizes grip and pull-out strength along the entire 38mm length for a more secure hold.
• Guaranteed dimensional precision and performance compliance with the stringent DIN 7504 N standard.

Professional Applications & Engineering Value

This M4.2 metric self-drilling screw is engineered to solve the critical industrial challenge of joining dissimilar materials quickly and securely. The zinc-plated steel body and specialized thread-forming design allow it to cut its own mating thread as it's driven, eliminating the separate tapping step and preventing cross-threading in sheet metal, aluminum frames, and wood assemblies. The 1.4mm thread pitch and fully threaded shank ensure a high number of engaged threads for superior tensile strength and resistance to vibrational loosening in machinery, HVAC ductwork, and structural fabrications. Its ability to drill through up to 3mm thickness without pilot holes streamlines production lines, reduces tooling requirements, and significantly lowers total installed cost for high-volume B2B manufacturing and construction projects.

Specification Summary & Compliance

This screw conforms to the dimensional and performance criteria of the DIN 7504 N standard (ISO 7049), ensuring precise metric thread geometry and reliable self-drilling function. It is manufactured from zinc-plated steel with a pan head, Phillips No. 2 drive, right-hand thread, and is fully threaded. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances for safe use in global markets.
