S-94209A347 M2.5 x 6 mm DIN 7500 C Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming capability in soft materials like aluminum, brass, and copper, reducing the need for pre-tapped holes and speeding up assembly.
• Enhanced corrosion resistance from the zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
• Efficient and secure drive engagement with the Phillips No. 1 drive, minimizing cam-out and allowing for consistent torque application.
• High pull-out strength and vibration resistance due to the tri-lobe shank design, which creates a secure, lasting fit in the base material.
• Broad material compatibility with coarse M2.5 x 0.45mm threads, providing excellent holding power in ductile metals.
• Full threading for maximum grip along the entire 6mm length, ensuring uniform stress distribution and a stronger assembly.
• Compliance with stringent industry standards including DIN 7500 C, guaranteeing dimensional accuracy and performance reliability.

Professional Applications & Engineering Value

This M2.5 tapping screw is engineered to solve common assembly challenges in aluminum, brass, and copper components, where traditional fasteners may strip threads or require additional tapping steps. The thread forming action of the tri-lobe shank displaces material to create strong, clean threads without generating chips, making it ideal for automated production lines and sensitive electronic enclosures. Made from zinc-plated steel, it offers excellent corrosion resistance, while the Phillips pan head provides a low-profile, flush finish. By integrating these features, this screw reduces installation time, minimizes part failure, and enhances the durability of assemblies in industries like automotive, HVAC, and metal fabrication.
