Professional Applications & Engineering Value

This M4.2 metric tapping screw is engineered to address common challenges in sheet metal assembly, such as material fatigue and loosening under vibration. The thread forming action cold-forms threads into the base material, eliminating the need for tapped holes and reducing installation steps. Made from 18-8 stainless steel, it offers excellent resistance to rust and corrosion, making it suitable for outdoor, marine, or chemical-exposed settings. The Phillips pan head and coarse thread design ensure quick driving and high clamp load retention, which is critical in industrial fasteners for HVAC, automotive, and electronics enclosures. By complying with DIN 7981, this screw delivers predictable performance and reduces the risk of fastener failure in demanding applications.

Specification Summary & Compliance
