• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
• High drive torque transmission via the Phillips No. 3 drive, minimizing cam-out and enabling efficient, secure fastening.
• Excellent material displacement and retention from the Tri-Lobe shank design, providing vibration-resistant, secure connections.
• Precise dimensional control with a length tolerance of -0.65 to 0.65mm, ensuring consistent fit and performance in automated assembly.
• Broad compatibility with coarse M6 x 1 mm metric threads, facilitating easy integration into standard industrial components.
• Regulatory peace of mind with compliance to DIN 7500 C, RoHS 3, and REACH, meeting strict international safety and environmental standards.

Professional Applications & Engineering Value

This M6 tapping screw is specifically engineered for demanding applications in aluminum, brass, and copper assemblies, where traditional fasteners may strip or loosen. The thread forming action of the Tri-Lobe shank displaces material to create strong, permanent threads without chips, eliminating the need for tapped holes and reducing assembly steps. Made from zinc-plated steel, it resists corrosion in humid or mildly corrosive settings, extending service life in electrical enclosures, automotive components, and HVAC systems. The Phillips drive and pan head design ensure easy installation with standard tools, while the fully threaded M6 x 1 mm coarse thread provides rapid engagement and high clamp load, making it ideal for high-volume production lines seeking reliability and efficiency.

Specification Summary & Compliance

This screw adheres to precise dimensional standards, including a length of 20 mm with a tolerance of -0.65 to 0.65mm, and features a metric M6 x 1 mm coarse thread with a right-hand direction and blunt tip. It conforms to the DIN 7500 C specification for thread-forming screws, ensuring consistent performance and interchangeability. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing the absence of hazardous substances and supporting sustainable manufacturing practices.
