- Superior corrosion resistance through zinc-plated steel construction ensuring long-term reliability in industrial environments
- Optimized countersinking performance with 80° flat head angle for flush mounting and clean finished appearance
- Maximum material penetration capable of drilling through 0.206" thickness without pilot holes
- Secure fastening integrity with fully threaded M5.5 design providing consistent holding power across entire length
- Industry-standard compatibility featuring Phillips No. 3 drive for common tooling and reduced stripping risk
- Reliable thread formation through BSD tapping screw design that creates precise mating threads in base materials
Professional Applications & Engineering Value
These M5.5 tapping screws deliver exceptional value in steel and sheet metal fabrication where time efficiency and joint integrity are critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the thread cutting technology eliminates costly pre-drilling operations. The 80° countersink angle ensures proper seating in standard chamfered holes, preventing head protrusion in precision assemblies. With fully threaded design and 10mm drill tip length, these screws maintain consistent performance across varying material thicknesses up to 0.206", making them ideal for HVAC systems, electrical enclosures, and automotive components where vibration resistance and structural stability are paramount.
Specification Summary & Compliance
These metric tapping screws feature M5.5 diameter with 25mm length and fully threaded right-hand configuration. Manufactured to ISO 15482 specifications where identified as DIN 7504 P, ensuring precise dimensional accuracy and thread form consistency. The zinc-plated steel construction meets RoHS 3 (2015/863/EU) compliance for hazardous substance restriction and REACH (EC 1907/2006) regulations for chemical safety, providing assurance for industrial procurement and international supply chain requirements.
