S-94209A367 M4 x 25 mm DIN 7500 C Tapping Screws

Key Features & Benefits at a Glance

• Superior thread-forming capability for reliable, vibration-resistant fastening in aluminum, brass, and copper without the need for pre-tapping.
• Enhanced corrosion resistance provided by the zinc-plated steel finish, extending the screw's service life in demanding industrial environments.
• High-strength tri-lobe shank design displaces material efficiently during installation, creating a secure, permanent thread with excellent pull-out resistance.
• Optimized Phillips No. 2 drive ensures common tool compatibility and efficient installation, reducing assembly time and labor costs.
• Precision-metric M4 x 0.7mm coarse thread with a 25mm length offers a robust and versatile fastening solution for a wide range of material thicknesses.
• Full threading and blunt tip facilitate easier starting and consistent engagement along the entire shank length for maximum holding power.
• Compliance with rigorous DIN 7500 C standards guarantees consistent quality, dimensional accuracy, and performance reliability for critical applications.

Professional Applications & Engineering Value

This M4 thread-forming screw is engineered to solve common fastening challenges in aluminum, brass, and copper assemblies. The zinc-plated steel construction provides a durable barrier against oxidation, making it ideal for applications where corrosion resistance is a priority. The unique tri-lobe shank cross-section and thread-forming design eliminate the need for a pre-tapped hole, reducing assembly steps and the risk of cross-threading. This results in faster production cycles and stronger, more reliable joints in sheet metal fabrication, electrical enclosures, and HVAC systems. The combination of a Phillips drive and pan head offers a balance of common tool use and a low-profile, finished appearance, delivering both functional and aesthetic value to your industrial fastening projects.
