Professional Applications & Engineering Value

These M4.8 metric tapping screws deliver exceptional engineering value in metal and sheet metal applications where reliable fastening is critical. The 18-8 stainless steel construction provides excellent corrosion resistance, making these thread cutting screws ideal for harsh environments while maintaining structural integrity. The combination of fully threaded design and pointed tip ensures quick penetration and secure fastening without requiring pre-tapped holes, significantly reducing installation time and labor costs. The oval head profile with 80° countersink angle creates a flush finish that eliminates snagging points and maintains clean aesthetics in visible applications. These Phillips drive screws are engineered to solve common industrial challenges including vibration loosening, material fatigue, and environmental degradation.

Specification Summary & Compliance

These metric tapping screws feature precise M4.8 thread diameter with 38mm length and right-hand thread direction, manufactured to DIN 7983/ISO 7051 standards for dimensional accuracy and performance reliability. The thread cutting technology (Type C) ensures proper thread formation in base materials without pre-tapping.
