• Reliable dimensional consistency with precise M3 x 0.5mm coarse thread profile and controlled length tolerance ensures uniform performance across production batches.
• Versatile material compatibility specifically engineered for aluminum, brass, and copper applications, providing secure fastening in soft metal assemblies.
• Enhanced installation stability with pan head design offering superior bearing surface and rounded profile for smooth, flush mounting in various applications.
• Full regulatory compliance meeting DIN 7500 C specifications and environmental standards including RoHS 3 and REACH for global industrial acceptance.

Professional Applications & Engineering Value

These thread forming screws deliver exceptional engineering value in aluminum, brass, and copper applications where traditional fastening methods often struggle. The tri-lobe shank cross-section displaces material during installation, creating precisely formed internal threads that eliminate the need for tapping operations and threaded inserts. This design significantly reduces assembly time while providing superior pull-out resistance compared to standard machine screws. The zinc-plated steel construction offers reliable corrosion protection for industrial environments, while the Phillips drive system ensures compatibility with common assembly tools. Particularly valuable in electrical enclosures, HVAC components, and automotive assemblies where vibration resistance and material compatibility are critical, these screws solve common challenges of strip-out and loosening in soft metal substrates.

Specification Summary & Compliance

This M3 x 0.5mm metric coarse thread screw features a 16mm length with manufacturing tolerance of -0.55 to 0.55mm, ensuring precise dimensional control. The fully threaded design with right-hand thread direction and blunt tip facilitates smooth installation. Manufacturing and performance comply with DIN 7500 C standards for thread forming screws, guaranteeing consistent quality and reliability. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making these screws suitable for global industrial applications with strict material restrictions.
