S-94209A338 M8 x 16 mm DIN 7500 D Tapping Screws

Key Features & Benefits at a Glance

• Superior material durability with zinc-plated steel construction, providing excellent corrosion resistance for long-lasting performance in demanding industrial environments.
• Effortless thread-forming installation thanks to the tri-lobe shank design, reducing driving torque and preventing material stripping in soft metals like aluminum, brass, and copper.
• Secure and reliable fastening with a coarse M8x1.25 thread pitch, ensuring strong holding power and vibration resistance in various assembly applications.
• Convenient external hex head drive allowing for quick and easy installation using standard tools, enhancing assembly efficiency and reducing labor time.
• Precise dimensional control with a tight length tolerance of -0.55 to 0.55mm, ensuring consistent fit and performance in automated or manual production lines.
• Full regulatory compliance meeting DIN 7500 D, RoHS 3, and REACH standards, guaranteeing safety and environmental responsibility for global supply chains.
• Versatile application range as a fully threaded screw with blunt tip, ideal for creating strong threads in non-ferrous metals without pre-drilling in many cases.

Professional Applications & Engineering Value

This M8 tapping screw is engineered to solve common fastening challenges in aluminum, brass, and copper assemblies. The zinc-plated steel material offers enhanced corrosion protection, while the tri-lobe shank cross-section and thread-forming design displace material during installation, creating precise, strong threads without chips. This eliminates the need for tapping operations, reduces assembly time, and minimizes the risk of loose fasteners in soft metals. The external hex drive and coarse metric thread (M8x1.25) ensure easy driving and reliable performance in high-vibration environments, making these screws ideal for automotive, electronics, and machinery applications where durability and efficiency are critical.

Specification Summary & Compliance

This screw features an M8 coarse thread with a 1.25 mm pitch and right-hand direction, fully threaded with a blunt tip. Key dimensions include a 16 mm length (tolerance: -0.55 to 0.55 mm), 13 mm head width, 8.35 mm head height, and 17 mm flange diameter. It conforms to DIN 7500 D specifications for thread-forming screws and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use in industrial applications.
