Key Features & Benefits at a Glance
- Superior thread-forming capability in softer materials like aluminum, brass, and copper, eliminating the need for pre-tapped holes and reducing assembly time.
- Exceptional vibration resistance and holding power thanks to the unique tri-lobe shank design that creates a secure, permanent fit.
- Enhanced corrosion resistance provided by the zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
- Optimized for high-torque installation with a standard external hex head, allowing for secure driving and preventing tool slippage.
- Reliable and consistent performance guaranteed by compliance with the stringent DIN 7500 D standard for thread-forming screws.
- Full-length threading for maximum grip and load distribution along the entire fastener length in your assembly.
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.
Professional Applications & Engineering Value
This M4 x 0.7 mm thread forming screw is engineered to solve common challenges in assembling non-ferrous metals. Its tri-lobe shank cross-section displaces material during installation, creating a strong, wear-resistant thread that resists loosening under vibration—a critical advantage in automotive, electronics, and machinery applications. Made from durable zinc-plated steel, it offers an excellent balance of strength and corrosion protection. The coarse pitch metric thread and fully threaded design ensure rapid installation and high pull-out strength in materials like aluminum, brass, and copper, streamlining production and enhancing the longevity of your final product.
Specification Summary & Compliance
This screw conforms to the DIN 7500 D specification for thread-forming screws. The M4 x 0.7 mm thread features a coarse spacing and a length tolerance of -0.65 to 0.65mm. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets the latest environmental and safety standards for industrial use.
