- Secure and efficient drive using a 5mm hex drive, providing high torque transfer and reducing the risk of tool slippage and head stripping.
- Precise and reliable threading with a Class 6g fit and coarse M8 x 1.25 mm thread, enabling quick assembly and strong holding power.
- Broad industry compliance meeting ISO 7380 standards, ensuring dimensional accuracy and interchangeability in global markets.
- Environmental and safety assurance with RoHS 3 and REACH compliance, making them safe for use in regulated industries.
Professional Applications & Engineering Value
This M8 flanged button head screw is engineered to solve critical challenges in industrial assembly. The 316 stainless steel material provides exceptional resistance to chemicals and saltwater corrosion, making it a top choice for marine, chemical processing, and food-grade equipment. The fully threaded design and coarse thread pitch ensure rapid installation and high vibration resistance, reducing the risk of loosening in dynamic environments. The integrated flange eliminates the need for a separate washer, speeding up assembly lines and providing a larger bearing surface to prevent damage to softer materials. Combined with the secure hex drive, these screws deliver reliable performance in machinery, automotive sub-assemblies, and structural frameworks where metric fasteners with ISO 7380 certification are specified for precision and durability.
Specification Summary & Compliance
This screw features an M8 x 1.25 mm coarse thread with a Class 6g tolerance for precise fit. It is manufactured to the dimensional requirements of ISO 7380 and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
