S-94209A361 M4 x 6 mm DIN 7500 C Tapping Screws

Key Features & Benefits at a Glance

• Superior Material Integrity: Zinc-plated steel construction ensures excellent corrosion resistance, extending service life in demanding industrial environments.
• Optimized Thread Design: The M4 coarse thread with a 0.7mm pitch provides faster installation and superior pull-out resistance in softer materials.
• Enhanced Holding Power: The unique tri-lobe shank design creates a secure, vibration-resistant fit by displacing material during installation.
• Efficient Drive System: The No. 2 Phillips drive offers a common and reliable interface for high-torque assembly without cam-out.
• Broad Material Compatibility: Specifically engineered for reliable thread forming in aluminum, brass, and copper without the need for pre-tapping.
• Precision Manufacturing: Fully threaded blunt tip and controlled length tolerance ensure consistent performance and ease of insertion.
• Regulatory Assurance: Compliant with RoHS 3 and REACH, meeting strict environmental and safety standards for global supply chains.

Professional Applications & Engineering Value

These M4 thread forming screws are precision-engineered to solve common fastening challenges in aluminum, brass, and copper assemblies. The zinc-plated steel material provides a durable, corrosion-resistant finish ideal for electronics enclosures, HVAC components, and automotive sub-assemblies. The tri-lobe shank cross-section and coarse thread pitch work synergistically to create strong, permanent threads in ductile metals, eliminating the need for tapped holes and reducing assembly time by up to 50%. The fully threaded design with Phillips drive ensures maximum engagement length and reliable installation with standard tools, making these metric tapping screws essential for high-volume production environments requiring consistent clamp load and vibration resistance.

Specification Summary & Compliance

This M4 x 0.7mm thread forming screw maintains precision length tolerance of -0.375 to 0.375mm and complies with DIN 7500 C manufacturing standards for thread forming screws. The right-hand coarse thread with fully threaded blunt tip design ensures reliable performance in accordance with metric thread specifications. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, confirming adherence to international substance restriction requirements.
