S-94209A321 M4 x 12 mm DIN 7500 D Tapping Screws

Key Features & Benefits at a Glance

• Superior pull-out resistance in soft materials like aluminum, brass, and copper due to the unique tri-lobe shank design
• Vibration-proof fastening that maintains joint integrity under dynamic loads and harsh conditions
• Corrosion-resistant zinc plating on steel for enhanced durability and longevity in industrial environments
• Easy installation with external hex drive providing reliable torque transmission and quick assembly
• Thread forming capability eliminates the need for pre-tapping, reducing assembly time and costs
• Precise M4 x 0.7 mm coarse thread ensures optimal grip and load distribution in various applications
• Full compliance with DIN 7500 D and environmental regulations for guaranteed quality and safety

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M4 thread forming screw excels in fastening aluminum, brass, and copper components where traditional screws may fail. The tri-lobe shank cross-section displaces material during installation, creating a secure, high-retention fit that prevents loosening from vibrations—a common issue in machinery and automotive assemblies. Made from zinc-plated steel, it offers excellent corrosion resistance, while the external hex drive allows for efficient installation with standard tools. Ideal for electronics enclosures, HVAC systems, and metal fabrications, this screw reduces the risk of strip-out and enhances structural reliability in coarse thread applications, delivering consistent performance and lower total cost of ownership.

Specification Summary & Compliance

This screw features an M4 x 0.7 mm coarse metric thread with a length tolerance of -0.55 to 0.55 mm, ensuring precise fit. It conforms to DIN 7500 D for thread forming screws and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting industry standards for safety and environmental responsibility.
