S-94209A368 M4 x 30 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 pre-tapping.
• Enhanced corrosion resistance from zinc-plated steel construction, ensuring long-term durability in various industrial environments.
• Optimized drive efficiency with Phillips No. 2 drive and pan head design for secure, easy installation and reduced cam-out risk.
• High material displacement from the tri-lobe shank cross-section, creating strong, permanent threads in ductile metals.
• Full thread engagement along the 30mm length provides maximum grip and load distribution in assembled components.
• Precision dimensional control with tight length tolerance ensures consistent performance and interchangeability in automated or manual assembly.
• Broad regulatory compliance meets DIN 7500 C for quality, plus RoHS 3 and REACH for environmental and safety standards.

Professional Applications & Engineering Value

This M4 thread forming screw is engineered to solve common fastening challenges in aluminum, brass, and copper assemblies, where traditional threading methods can cause material cracking or strip threads. The tri-lobe shank design displaces material during installation, forming precise metric coarse threads (M4 x 0.7mm) that enhance pull-out strength and resist loosening under vibration. Made from zinc-plated steel, it offers excellent corrosion resistance, extending service life in electrical enclosures, HVAC systems, and automotive components. The Phillips No. 2 drive and pan head facilitate quick installation with standard tools, reducing assembly time and improving production throughput in high-volume manufacturing and maintenance operations.

Specification Summary & Compliance

This screw features M4 x 0.7mm coarse metric threads with a 30mm length and tolerance of -0.65 to 0.65mm, ensuring precise fit. It is fully threaded with a right-hand thread direction and blunt tip for controlled entry. Manufactured to DIN 7500 C standards for thread forming screws, it is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting strict environmental and health regulations for industrial use.
