Key Features & Benefits at a Glance
- Superior material resistance with zinc-plated steel providing excellent corrosion protection for long-lasting performance in demanding environments.
- Optimized thread forming design with tri-lobe shank ensures high resistance to vibration loosening and superior pull-out strength in soft materials.
- Efficient installation and removal thanks to the external hex drive and right-hand thread direction, allowing for quick assembly with standard tools.
- Reliable dimensional accuracy with a length tolerance of ±0.8mm and M8 coarse thread pitch for consistent, secure fastening every time.
- Enhanced material compatibility specifically engineered for use in aluminum, brass, and copper without pre-tapping, reducing installation time and cost.
- Full compliance with industry standards including DIN 7500 D, RoHS 3, and REACH, ensuring safety, quality, and regulatory adherence for industrial applications.
- Robust flange and blunt tip design increases load distribution and prevents damage to sensitive materials during insertion.
Professional Applications & Engineering Value
This M8 tapping screw is engineered with thread forming technology and a tri-lobe shank cross-section to create strong, permanent threads in ductile metals like aluminum, brass, and copper. The zinc-plated steel construction offers durability against corrosion, while the coarse metric thread (1.25mm pitch) and fully threaded design ensure maximum grip and vibration resistance in automotive, electronics, and machinery assemblies. By eliminating the need for pre-tapped holes, it reduces labor and tooling costs, providing a reliable fastening solution that meets strict DIN 7500 D specifications for high-strength applications.
Specification Summary & Compliance
The screw features a metric M8 x 1.25mm coarse thread with standard Class 2A dimensional tolerances, ensuring precise fit. It is manufactured in compliance with DIN 7500 D for thread-forming screws and adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming it is free from hazardous substances and suitable for global industrial use.
