Professional Applications & Engineering Value
This M3.9 x 38mm oval head tapping screw is engineered to solve common fastening challenges in metal and sheet metal assemblies. Its 18-8 stainless steel construction provides excellent resistance to rust and corrosion, making it ideal for demanding environments like outdoor equipment, machinery, and HVAC systems. The thread cutting (Type C) design allows the screw to form its own threads as it is driven, reducing the risk of material cracking and eliminating the need for additional tapping operations. Combined with a Phillips No. 2 drive and fully threaded profile, it ensures quick installation and superior pull-out resistance, enhancing assembly efficiency and structural integrity in industrial applications.
Specification Summary & Compliance
This screw features a metric M3.9 thread diameter and 38 mm length with standard Class 2A / ISO tolerance for precise fit. It conforms to DIN 7983 and ISO 7051 manufacturing specifications, ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting environmental and safety standards for industrial use.
