Professional Applications & Engineering Value

This M4.8 x 16mm metric tapping screw is engineered to address common challenges in metal and sheet metal fabrication, where vibration resistance, material integrity, and installation efficiency are critical. The 18-8 stainless steel composition provides inherent resistance to oxidation and chemical exposure, making it ideal for outdoor equipment, electrical enclosures, and automotive assemblies. Its thread cutting (Type C) design eliminates the need for separate tapping operations, reducing production steps and minimizing the risk of thread stripping in thin-gauge materials. The fully threaded configuration ensures consistent clamping force across the entire engagement length, while the oval head and Phillips drive facilitate quick, tool-compatible fastening in confined spaces. By integrating DIN 7983 specifications, this screw delivers reliable performance in high-stress applications, from machinery frames to HVAC systems, enhancing structural stability and maintenance longevity.

Specification Summary & Compliance

This oval head Phillips tapping screw features precise metric dimensions: M4.8 thread diameter, 16mm length, 9.5mm head diameter, and a standard 80° countersink angle. It adheres to DIN 7983 (equivalent to ISO 7051) for thread form, tolerances, and mechanical properties, ensuring consistent fit and function. The screw is manufactured with fully threaded, right-hand threading and a pointed tip for optimal penetration. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms the absence of restricted substances, supporting sustainable and safe usage in industrial supply chains.
