S-94209A329 M5 x 25 mm DIN 7500 D Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power with tri-lobe shank design that forms threads in materials like aluminum, brass, and copper, reducing the need for pre-tapped holes and speeding up assembly.
• Enhanced corrosion resistance thanks to zinc-plated steel construction, ensuring long-term durability in various industrial environments.
• Easy and secure installation with an external hex drive and hex head, allowing for high torque application without slipping and minimizing tool wear.
• Reliable thread engagement through thread forming technology and coarse pitch (0.8 mm), providing strong vibration resistance and reduced loosening in soft materials.
• Precise dimensional control with a length tolerance of -0.65 to 0.65 mm, ensuring consistent fit and performance in automated or manual assembly processes.
• Broad material compatibility optimized for use in aluminum, brass, and copper, making it a versatile choice for diverse B2B applications in metalworking and electronics.
• Blunt tip design for easier alignment and reduced risk of material damage during insertion, improving overall assembly safety and efficiency.

Professional Applications & Engineering Value

This M5 x 0.8mm zinc-plated steel tapping screw is engineered to address common industrial challenges, such as the need for reliable fastening in soft metals without pre-drilled threads. The thread forming action and tri-lobe shank cross-section create strong, permanent threads in materials like aluminum, brass, and copper, eliminating tap costs and reducing assembly time. Its coarse pitch and right-hand thread direction ensure quick installation and high resistance to vibration, making it ideal for applications in automotive, electronics, and machinery where durability is critical. Compliant with DIN 7500 D, this screw offers consistent performance, while the external hex drive allows for efficient torque transfer, minimizing the risk of stripping and enhancing productivity in high-volume B2B settings.
