S-94209A365 M4 x 16 mm DIN 7500 C Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming capability in soft materials like aluminum, brass, and copper, creating strong, permanent threads without pre-tapping.
• Exceptional corrosion resistance provided by the zinc plating, extending the screw's service life in various industrial environments.
• High driving efficiency and reduced cam-out with the Phillips No. 2 drive, ensuring secure and straightforward installation.
• Enhanced pull-out and vibration resistance due to the tri-lobe shank design, which displaces material for a secure, tight fit.
• Maximum holding power and load distribution from the fully threaded design, providing consistent strength along the entire fastener length.
• Reliable dimensional consistency with a controlled length tolerance, ensuring predictable performance and ease of assembly.
• Broad industrial compliance meeting DIN 7500 C, RoHS 3, and REACH standards for guaranteed quality and environmental safety.

Professional Applications & Engineering Value

This M4 metric thread forming screw is engineered to solve common fastening challenges in aluminum, brass, and copper assemblies. The zinc-plated steel construction offers a durable, corrosion-resistant base, while the tri-lobe shank and thread forming (tapping) method work together to cold-form a mating thread. This eliminates the need for a pre-tapped hole, reducing assembly steps, minimizing the risk of cross-threading, and creating a stronger thread with superior resistance to loosening under vibration. The Phillips drive and pan head design provide a balance of high torque transfer and a low-profile finish, making these tapping screws an efficient and reliable choice for electronics enclosures, automotive components, and machinery where durable threads in soft metals are critical.

Specification Summary & Compliance

This screw conforms to the dimensional and performance specifications of DIN 7500 C for thread-forming screws. The metric thread is M4 x 0.7mm with a coarse pitch and is fully threaded for maximum grip. The length tolerance is controlled between -0.55 to 0.55mm. This product is manufactured to be compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances for use in global markets.
