S-94209A335 M6 x 20 mm DIN 7500 D Tapping Screws

Key Features & Benefits at a Glance

• Superior Thread Forming: Tri-lobe shank design creates strong, permanent threads in materials like aluminum, brass, and copper without pre-drilling, reducing assembly steps and increasing productivity.
• Enhanced Corrosion Resistance: Zinc-plated steel construction provides reliable protection against rust and environmental factors, ensuring long-term durability in demanding industrial settings.
• High Torque Application: External hex head allows for secure tool engagement and high torque transfer, minimizing stripping and enabling efficient installation with standard tools.
• Optimized for Soft Materials: Coarse M6 x 1 mm thread pitch ensures excellent grip and pull-out resistance in non-ferrous metals, preventing loosening under vibration.
• Full Compliance Assurance: Meets DIN 7500 D standards for thread-forming screws, ensuring consistent quality, dimensional accuracy, and reliable performance in professional applications.
• Precision Length Control: 20 mm length with tight tolerance (-0.65 to 0.65mm) guarantees proper fit and secure fastening, reducing the risk of assembly errors.
• Environmental and Safety Compliance: RoHS 3 and REACH compliant, making these screws safe for various industries and supporting sustainable manufacturing practices.

Professional Applications & Engineering Value

This M6 tapping screw is engineered with a tri-lobe shank and thread forming design to solve common issues in fastening aluminum, brass, and copper components. By displacing material rather than cutting it, the screw forms precise, robust threads that resist vibration loosening and improve joint integrity. The zinc-plated steel material offers excellent corrosion resistance, extending service life in humid or outdoor environments. Ideal for metric coarse thread applications, these screws provide high clamp load and reliability in assemblies such as electrical enclosures, automotive parts, and machinery frames. With external hex drive compatibility, they enable quick installation using standard wrenches, reducing labor time and enhancing overall assembly efficiency in B2B industrial settings.

Specification Summary & Compliance

This screw features an M6 x 1 mm metric coarse thread with a length of 20 mm and tolerance of -0.65 to 0.65mm, ensuring precise fit. It complies with DIN 7500 D for thread-forming screws, guaranteeing dimensional accuracy and performance. The product is fully threaded with a blunt tip and tri-lobe shank cross-section, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards for environmental safety and regulatory compliance.
