• Secure and flush seating with the standard oval head profile and 80° countersink angle, providing a smooth finish and enhanced vibration resistance.
• Full-length threading for maximum grip and holding power along the entire 22mm length, ensuring a strong, reliable fastening in thin materials.
• Pointed tip for easy alignment and quick starting, speeding up assembly processes and improving installation accuracy.
• Compliance with international standards including DIN 7983 and ISO 7051, guaranteeing consistent quality, dimensional accuracy, and interchangeability.

Professional Applications & Engineering Value

These M3.5 x 22mm tapping screws are engineered to solve critical fastening challenges in metal and sheet metal assemblies. The 18-8 stainless steel material provides excellent resistance to oxidation and corrosion, making these screws ideal for outdoor equipment, electrical enclosures, and automotive components exposed to moisture. The thread cutting feature allows the screw to form its own thread in pre-drilled holes, eliminating the need for separate tapping operations and reducing labor costs. Combined with the Phillips drive and oval head, this design ensures a secure, flush fit that withstands vibration and mechanical stress, enhancing the durability and safety of the final product in demanding industrial settings.
