Professional Applications & Engineering Value

These M3.5 x 16mm tapping screws are engineered to solve common fastening challenges in metal and sheet metal applications. The 18-8 stainless steel material provides excellent resistance to oxidation and chemical exposure, making them ideal for outdoor, marine, or high-moisture environments. The thread cutting feature allows the screw to form its own thread in pre-drilled holes, eliminating the need for tapping operations and reducing assembly time. Combined with a Phillips drive and fully threaded design, they ensure quick installation and superior pull-out resistance. The oval head sits flush for a clean finish, while compliance with DIN 7983 and ISO 7051 guarantees dimensional accuracy and performance reliability in automotive, electronics, and machinery assemblies.
