• Quick and efficient installation with coarse 0.7mm pitch and fully threaded design, reducing assembly time and labor costs.
• Consistent performance and dimensional accuracy with length tolerance of -0.8 to 0mm, ensuring precise fit in metric applications.
• Broad material compatibility for use in non-ferrous metals, making these screws versatile for diverse B2B manufacturing needs.
• Compliance with environmental and safety standards, including RoHS 3 and REACH, supporting sustainable and regulated procurement practices.

Professional Applications & Engineering Value

These M4 tapping screws are engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may cause material deformation or poor holding strength. The thread forming design with a tri-lobe shank creates strong, permanent threads without cutting, reducing chip formation and enhancing joint integrity in soft metals. Made from zinc-plated steel, they offer durability against corrosion, while the Torx Plus drive (IP20/T20) ensures maximum torque transfer and anti-camout, minimizing tool wear and assembly errors. Ideal for industries like electronics, automotive, and machinery, these metric coarse screws provide reliable fastening solutions that improve production efficiency and product longevity.
