Key Features & Benefits at a Glance
- Superior thread forming capability in soft materials like aluminum, brass, and copper, ensuring reliable, vibration-resistant fastening without pre-tapping.
- Enhanced corrosion resistance from the zinc-plated steel construction, extending service life in various industrial environments.
- High driving efficiency with the Phillips No. 1 drive and pan head design, allowing for quick installation and reduced assembly time.
- Excellent material displacement and retention due to the tri-lobe shank cross-section, creating strong, permanent threads.
- Full threading along the 4 mm length provides maximum grip and uniform stress distribution for consistent clamping force.
- Broad compatibility with coarse M3 x 0.5 mm metric threads, making them ideal for standard industrial applications.
- Assured quality and safety through compliance with DIN 7500 C, RoHS 3, and REACH, meeting strict regulatory and performance standards.
Professional Applications & Engineering Value
These M3 x 0.5 mm thread forming screws are engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may strip threads or loosen under stress. The zinc-plated steel material offers durability and corrosion protection, while the tri-lobe shank and thread forming design displace material to form precise, high-strength threads without chips or debris. This eliminates the need for pre-tapped holes, reducing assembly steps and minimizing failure risks in industrial equipment, electronics, and automotive assemblies. The Phillips drive and pan head ensure easy installation, making these screws a cost-effective solution for high-volume production lines requiring reliable, long-lasting connections.
Specification Summary & Compliance
This product features an M3 metric coarse thread with a 0.5 mm pitch and fully threaded 4 mm length (tolerance: -0.375 to 0.375 mm). It conforms to DIN 7500 C for thread forming screws and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability in professional use.
