S-90469A121 Length 38 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated No. 2 drill tip, saving time and labor costs in steel and sheet metal assembly.
• Superior corrosion resistance from zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments.
• High-torque installation enabled by the external hex drive and robust hex head, preventing tool slippage and ensuring secure fastening.
• Enhanced load distribution and vibration resistance due to the integrated flange design, reducing the risk of loosening under stress.
• Strong, permanent threads created by the thread-forming (BSD) tapping method, providing excellent pull-out strength in ductile materials.
• Full 38mm thread engagement offers maximum grip length for secure fastening in varied material thicknesses.
• Guaranteed performance and material safety through compliance with DIN 7504 K, RoHS 3, and REACH standards.

Professional Applications & Engineering Value

This M4.2 x 38mm zinc-plated steel tapping screw is engineered to solve critical challenges in metal fabrication and assembly. Its self-drilling tip and thread-forming design allow for direct installation into steel and sheet metal up to 0.118" thick, eliminating separate drilling and tapping operations. This significantly accelerates production lines and reduces assembly costs. The flanged hex head provides a larger bearing surface, which helps prevent pull-through and maintains clamp force under dynamic loads and vibration, making it ideal for HVAC systems, electrical enclosures, and automotive components. Manufactured to DIN 7504 K specifications, it delivers consistent, reliable performance for high-volume industrial fastening applications.

Specification Summary & Compliance

This flanged tapping screw features an M4.2 size, a 38mm fully threaded length, and a right-hand thread direction. It conforms to the dimensional and performance requirements of DIN 7504 K (referencing ISO 15480) for self-drilling screws. The product is manufactured from zinc-plated steel and is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it is free from hazardous substances for safe use in regulated markets.
