Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments
- Efficient thread cutting design creates precise mating threads in metal and sheet metal without pre-drilling, reducing installation time and labor costs
- Optimized Phillips drive system (No. 2 size) provides secure tool engagement and prevents cam-out during high-torque applications
- Fully threaded shank delivers maximum grip length and uniform load distribution across the entire fastener length
- Streamlined oval head profile with 80° countersink angle sits flush with surfaces for clean, professional finishes
- Precision metric dimensions (M4.2 x 19mm) ensure consistent performance and interchangeability in metric-based assemblies
- Comprehensive regulatory compliance meets DIN 7983/ISO 7051 specifications plus RoHS 3 and REACH environmental standards
Professional Applications & Engineering Value
These M4.2 metric tapping screws deliver exceptional engineering value in metal and sheet metal fabrication applications. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, while the thread cutting technology eliminates the need for separate tapping operations - significantly reducing assembly time and production costs. The fully threaded design ensures maximum pull-out strength in thin materials, and the Phillips drive system offers reliable installation with standard industrial tools. These oval head screws create finished appearances in automotive, electronics, and machinery assemblies where both performance and aesthetics matter.
Specification Summary & Compliance
Manufactured to DIN 7983/ISO 7051 standards with precision metric threading (M4.2 diameter, 19mm length). Features fully threaded right-hand configuration with standard thread pitch for consistent engagement. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications worldwide. The oval head design maintains specified dimensions (8.1mm head diameter, 3.9mm head height) with 80° countersink angle for proper seating in prepared holes.
