S-94209A358 M3 x 12 mm DIN 7500 C Tapping Screws

Key Features & Benefits at a Glance

• Superior thread-forming capability for reliable, vibration-resistant fastening in soft materials like aluminum, brass, and copper without the need for pre-tapping.
• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in various industrial environments.
• Optimized drive engagement using a Phillips No. 1 drive and tri-lobe shank design to minimize cam-out and ensure efficient installation.
• High dimensional precision with a length tolerance of ±0.55 mm, ensuring consistent fit and performance in automated or manual assembly.
• Wide material compatibility due to the coarse M3 x 0.5 mm thread pitch, providing strong holding power in non-ferrous metals.
• Full compliance with DIN 7500 C and environmental standards like RoHS 3 and REACH, guaranteeing safety and regulatory adherence for global supply chains.
• Versatile pan head design with a rounded profile for easy handling and a flush finish in diverse applications.

Professional Applications & Engineering Value

These M3 tapping screws are engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may strip threads or loosen under stress. The thread-forming action of the tri-lobe shank creates precise, durable threads in soft materials, reducing the risk of material cracking and improving pull-out strength. Made from zinc-plated steel, they offer excellent corrosion resistance, ideal for electronics, automotive, and HVAC assemblies. The Phillips No. 1 drive and fully threaded blunt tip enable quick, secure installations, minimizing assembly time and enhancing productivity in high-volume manufacturing. By meeting DIN 7500 C standards, these screws ensure consistent quality and reliability, making them a trusted choice for engineers seeking efficient, compliant fastening solutions.

Specification Summary & Compliance

This M3 x 0.5 mm metric screw features a coarse thread spacing, 12 mm length with a tolerance of -0.55 to 0.55 mm, and a standard pan head with a 6 mm diameter. It complies with DIN 7500 C for thread-forming screws and is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations. The right-hand thread and fully threaded design provide uniform fastening performance across applications.
